Best Snorkels for the 79 Series LandCruiser — Aftermarket Guide

The 79 Series LandCruiser is Toyota's most capable working ute, and the environments it works in are exactly the ones that put the most stress on an unprotected air intake. Station work in the Pilbara means corrugated tracks in fine red bulldust that hangs in the air and loads an air filter in a fraction of the time it would on sealed roads. River crossings on Cape York or the Kimberley present a factory intake height that is not designed for serious water. Touring through the Simpson or the Strzelecki puts weeks of dust through the engine. Fitting a snorkel is one of the most practical and protective modifications a 79 Series owner can make, and the quality of the snorkel matters as much as fitting one at all.

Why the Factory Air Intake on the 79 Series Falls Short

The factory air intake on the VDJ79 draws air from a point low in the engine bay, near the front of the vehicle. This position is functional for the vehicle's original intended duty and sits well below the level at which road dust, water spray from the front wheels, and water from crossings can enter the intake tract. At highway speed on a dirt road, the air immediately above the bonnet is loaded with suspended fine particles - bulldust, clay, and silica - that settle into the intake and progressively load the air filter. A clogged air filter restricts airflow to the 1VD-FTV's twin turbos, increases fuel consumption, reduces power, and accelerates wear on the turbo bearings and intercooler.

For water crossings, the picture is more serious. The factory intake height provides limited clearance above the waterline in any crossing of moderate depth. Water ingestion into a diesel engine causes hydrostatic lock - the incompressible water prevents the piston completing its stroke and the resulting force is sufficient to bend or break a connecting rod. On the 1VD-FTV, a connecting rod failure is a total engine loss. The 1VD-FTV is a complex and expensive engine, and the cost of an engine rebuild or replacement is orders of magnitude beyond the cost of a quality snorkel that eliminates the risk entirely.

What a Snorkel Actually Does

A snorkel relocates the air intake from low in the engine bay to the upper A-pillar, placing the inlet at approximately roof height. This raises the effective wading depth from the factory level to well above the windscreen line - typically 1.8 to 2 metres from the ground - putting the air source well above the water level in all but the most extreme crossings. The intake is no longer positioned where it can draw in water splash from the front wheels, water from bow waves in river crossings, or the densest concentration of road dust that hangs at bonnet level on dirt roads.

The ram head at the top of the snorkel does more than simply relocate the intake point. The forward-facing ram is shaped to create a cyclonic airflow effect inside the head - water droplets and heavy dust particles are separated from the incoming air by centrifugal force before they reach the airbox. Water drains from a drain hole in the base of the ram; coarser dust particles settle out before reaching the filter element. The air that arrives at the engine is cleaner than what a low-mounted factory intake delivers even in dry conditions, and significantly cleaner in rain, river crossings, and bulldust environments. The result is extended air filter life, reduced dust loading on the turbo and intercooler, and protection against water ingestion in crossings.

ARMAX vs V-Spec: Which Safari Snorkel Is Right for Your 79 Series?

Safari Snorkels produces two distinct snorkel lines for the VDJ79 and the choice between them comes down to one question: has the engine been modified or is it running stock? Getting the answer right matters because the two products are engineered for different airflow requirements.

Safari ARMAX: For Modified Engines

The Safari ARMAX snorkel uses a 4-inch air ram and delivers a 100% increase in airflow over the standard factory air intake assembly. This additional airflow capacity is designed for 79 Series engines that have been modified beyond factory specification - exhaust upgrades, ECU tunes, or other performance modifications that increase the engine's air demand. When a modified 1VD-FTV is drawing more air than the factory intake is rated to supply, the ARMAX provides the headroom needed to support that demand without the intake becoming a bottleneck. The ARMAX is the correct choice for any 79 Series owner who has already fitted an aftermarket exhaust and tune, or who is planning to do so.

Safari V-Spec: For Standard Engines

The Safari V-Spec snorkel uses a 3.5-inch air ram and delivers airflow equivalent to the factory intake assembly - sufficient to meet the 1VD-FTV's air demand at standard output without creating excess flow that the standard tune is not calibrated to use. For a 79 Series running a standard engine with no performance modifications, the V-Spec delivers all the protective benefits of a quality snorkel - water separation, dust reduction, raised intake position - without oversizing the airflow for an engine that does not need it. The V-Spec is the correct starting point for owners who want the protection benefits of a snorkel before any engine modifications are made.

The DPF Benefit: Why Post-2016 Owners Should Pay Attention

79 Series models produced from November 2016 onwards are fitted with a diesel particulate filter as part of the Euro 5 emissions compliance update. The DPF captures soot from the combustion process and periodically burns it off in a regeneration cycle that requires sustained high exhaust temperatures. One of the factors that contributes to efficient, complete DPF regeneration is clean, dense combustion - which depends directly on the quality of the air entering the engine.

An air intake contaminated with fine dust particles delivers abrasive material to the combustion chamber, which increases soot production and loads the DPF faster than clean-air combustion would. A partially loaded or clogged air filter restricts airflow and creates a rich mixture that generates more particulate. A snorkel - by raising the intake above the heaviest dust concentration and providing cyclonic pre-separation before the filter element - delivers cleaner air to the engine than the factory intake does in the conditions a 79 Series typically operates in. The practical result is a DPF that loads more slowly, regenerates more completely, and requires less intervention over the vehicle's service life. For owners who run their 79 Series in consistently dusty environments, this is a meaningful benefit beyond the protection the snorkel provides against water ingestion.

Fitment Guide: Which Snorkel Fits Your 79 Series?

The 79 Series has used two distinct front-end profiles across its production run, and the snorkel fitment corresponds to the body generation rather than the cab configuration. Single cab and dual cab 79 Series share the same A-pillar and front guard structure, so the same snorkel fits both body styles within the same generation. The fitment split is generation-based, not cab-based.

The key fitment point for the 79 Series is the 2007 front end change. The introduction of the V8 engine required a wider front guard profile, and the snorkel that mounts to the narrow pre-2007 front end will not fit the wide VDJ body. If your 79 Series is a VDJ single cab or dual cab from March 2007 to 2023, the wide-front Safari snorkel is the correct product. The 2024 facelift introduced further changes to the front end that require its own specific fitment.

Australian Made: Why It Matters for a Snorkel

Safari Snorkels are manufactured in Australia and use UV-stable cross-linked polyethylene as their base material. Cross-linked polyethylene is a fundamentally different material from the standard high-density polyethylene or ABS plastic used in cheaper snorkel alternatives. The cross-linking process creates a polymer structure that is significantly more resistant to UV degradation, temperature cycling, and impact than non-cross-linked alternatives. In the Australian sun - particularly on a vehicle that spends time in northern Queensland, the Northern Territory, or Western Australia - a snorkel that is not UV-stable will begin to chalk, fade, and become brittle within a few years. Safari's material maintains its structural integrity and finish over the life of the vehicle, which is why they back it with a lifetime warranty.

The precision of the mounting system is the other Australian manufacturing advantage. Each Safari snorkel is designed and fitted to the specific guard, A-pillar, and firewall contours of the relevant vehicle generation. The mounting brackets and sealing system are developed to the exact panel geometry of the 79 Series front end, delivering a flush, water-tight fit that maintains the vehicle's structural rigidity at the mounting points. A generic imported snorkel that approximates the fit with generic hardware creates gaps, potential water ingress points, and a mounting system that does not distribute loads as Toyota's panel structure was designed to handle.

Frequently Asked Questions

Does a snorkel make a 79 Series LandCruiser truly waterproof for river crossings?

A snorkel addresses the air intake, which is the primary point of failure in a deep water crossing for a diesel engine. With a snorkel fitted, the air intake is raised to approximately 1.8 to 2 metres from the ground, well above the water level in any crossing a standard 79 Series would undertake. However, a snorkel alone does not make the entire vehicle waterproof - differentials, the gearbox, transfer case, and electrical components also have depth limits. A snorkel removes the air intake as the limiting factor and allows the vehicle to operate at depths that would cause hydrostatic lock in an unsnorkelled engine, but proper river crossing preparation involves assessing depth, current, and the whole vehicle's capability.

What is the difference between the ARMAX and V-Spec snorkel for the 79 Series?

The ARMAX uses a 4-inch air ram and delivers 100% more airflow than the factory intake, designed for modified engines with increased air demand from exhaust or ECU upgrades. The V-Spec uses a 3.5-inch ram and delivers factory-equivalent airflow, designed for standard unmodified engines. Both provide identical water separation, dust reduction, raised intake position, and protection benefits - the choice between them is purely about matching airflow capacity to the engine's state of tune.

Will the same snorkel fit both the 79 Series single cab and dual cab?

Yes. The snorkel mounts to the A-pillar and front guard of the 79 Series, and this structure is identical between the single cab and dual cab configurations. Both body styles use the same wide-front guard panel and A-pillar profile from 2007 onwards, so a single snorkel product covers both cab configurations within the same model year generation.

Does a snorkel help with the 79 Series DPF on post-2016 models?

Yes, indirectly but meaningfully. The DPF regeneration cycle depends on clean, efficient combustion. Cleaner air delivered by a snorkel - through a raised intake position above the densest dust concentration and cyclonic pre-separation in the ram head - reduces the particulate loading on the DPF and supports more complete regen cycles. In consistently dusty operating conditions, this can reduce the frequency of forced regen events and extend the service life of the DPF filter element.

Does fitting a snorkel affect the 79 Series factory warranty?

Fitting an aftermarket snorkel does not void the Toyota factory warranty in Australia. Under Australian Consumer Law, a manufacturer cannot void a warranty simply because an aftermarket accessory has been fitted - they would need to demonstrate that the accessory caused the specific failure being claimed. A Safari Snorkel fitted correctly to the 79 Series does not affect the engine, driveline, or any warranted component in a way that would support a warranty refusal. For specific warranty concerns, confirm with your Toyota dealer before fitting.

How long does a Safari Snorkel last on a 79 Series?

Safari Snorkels carry a lifetime warranty, which reflects the durability of the UV-stable cross-linked polyethylene construction. The material does not yellow, chalk, fade, or become brittle under Australian UV exposure and temperature cycling over the vehicle's life. Properly installed, a Safari snorkel is expected to outlast the vehicle it is fitted to. The lifetime warranty is a genuine product commitment rather than a marketing claim - it covers manufacturing defects and material failures for as long as you own the vehicle.
