ARB Safari Snorkel: Lexus LX470 & Land Cruiser Guide

A Lexus LX470 snorkel moves your engine's air intake from the bottom of the fender to the top of the A-pillar, so the 4.7L V8 keeps breathing clean, dry air when you cross water or run dusty trails. For the 1998–2007 LX470 and its twin, the Toyota Land Cruiser 100 Series, the ARB Safari 4X4 Armax snorkel (part SS86HP) is the part we install most at NLP Performance. It is flow-bench tested to move 25–70% more air than the factory air-cleaner housing, carries a lifetime warranty, and bolts to a chassis built for serious overlanding. This guide covers why a snorkel matters, the difference between ARB's Armax, V-Spec and R-Spec ranges, real 2UZ-FE V8 power figures, install reality, and the rest of the ARB Safari snorkel family for the Toyota and Lexus 4x4 lineup.

Why Put a Snorkel on a Lexus LX470 or Land Cruiser 100 Series?

A snorkel raises your engine's air intake to roof or A-pillar height so the vehicle can ingest clean, dry, cooler air in conditions that would choke a factory intake. On a stock 1998–2007 LX470 or 100 Series, the air enters through the inner fender, roughly 24 to 30 inches off the ground. A snorkel relocates that opening to about 70 inches, near the top of the windshield pillar. That single change does three important jobs.

It protects against hydrolock during water crossings

Hydrolock is engine damage that happens when water is drawn into a cylinder. Because liquid cannot be compressed, the piston cannot complete its stroke — the result is bent connecting rods or, in severe cases, a cracked block. By moving the air intake well above the waterline, a snorkel dramatically reduces the risk of water reaching the engine during a crossing. Industry rule-of-thumb is that a roof-height intake adds roughly 3 to 4 feet of safe fording height above a factory wading limit of about 20 to 30 inches, though actual safe depth always depends on current, technique, and how the rest of the truck is sealed.

It keeps the air filter cleaner on dusty trails

Dust concentration is highest near the ground where tires kick it up. Pulling intake air from A-pillar height means the air filter sees noticeably less particulate, so it stays cleaner longer and the engine gets more consistent airflow on long desert or fire-road runs. ARB's water-separating "air ram" head is specifically designed to strip rain and spray out of the airstream before it reaches the filter.

It supports future power and intake upgrades

A snorkel is not a bolt-on power adder on a stock engine, but a restrictive intake will cap any mods you add later. The Armax body's larger cross-section means the 2UZ-FE V8 is never starved for air, so it pairs cleanly with a high-flow air filter, throttle-body work, or a tune down the road.

ARB Safari Armax vs V-Spec vs R-Spec: What's the Difference?

ARB sells Safari snorkels in three distinct ranges, and choosing the right one matters more than most buyers realize. Here is how they compare.

Armax — the performance range

The Armax is ARB Safari's current premium, performance-focused snorkel. It is molded from UV-stabilized polyethylene, uses a broad-neck body with a larger cross-sectional area than the older designs, and feeds a 4-inch (102 mm) outlet. ARB's flow-bench testing shows the Armax delivers 25 to 70% more air than the vehicle's standard air-cleaner housing, depending on the application. The LX470 and 100 Series part, SS86HP, is an Armax snorkel.

V-Spec — the vehicle-specific range

The V-Spec is Safari's traditional vehicle-specific snorkel. It carries a lower-profile neck and is engineered so its airflow matches the factory air-cleaner housing — meaning it raises the intake for water and dust protection without adding flow over stock. It is the right pick when you want OEM-style looks and reliable wading capability rather than maximum airflow. ARB lists V-Spec snorkels for the Gen-4 Toyota 4Runner and the FJ Cruiser.

R-Spec — the traditional rugged range

The R-Spec uses Safari's long-standing molds and Australian manufacturing, and it covers classic platforms like the 80 Series Land Cruiser (part SS82R). It is the value choice for older rigs where an Armax body is not offered.

ARB Safari Armax SS86HP: Our Top Pick for the LX470 & 100 Series

The ARB Safari Armax SS86HP is purpose-built for the 1998–2007 Lexus LX470 and Toyota Land Cruiser 100 Series with the 4.2L, 4.5L, or 4.7L engine. It is the snorkel we recommend for almost every 100-platform build that sees water, dust, or both. Note that the kit is engineered around the cyclonic airbox, so the US-market rectangular airbox typically needs minor modification to mate to the snorkel — our Tampa install team handles that as part of a professional fit.

How Much Power Does the 4.7L 2UZ-FE V8 Make?

The Lexus LX470 and US-market Land Cruiser 100 Series share the 2UZ-FE, a 4.7-liter DOHC 32-valve V8. Early non-VVT-i versions (roughly 2000–2002) produced about 230 horsepower at 4,800 rpm and 320 lb-ft of torque at 3,400 rpm. When Toyota added VVT-i around 2003, output rose to roughly 235 horsepower, and the final 2006–2007 LX470 climbed to about 275 horsepower. That broad, torque-rich V8 hauls a roughly 5,400 to 5,600 lb truck, which is exactly why protecting it from hydrolock and dust is worth doing right.

Here is the useful part for shoppers: the same 2UZ-FE 4.7L V8 also powers the fourth-generation Toyota 4Runner (2003–2009), the Lexus GX470, and the Tundra and Sequoia of that era. So if you are building a 100-platform rig, the snorkel knowledge transfers directly across the Toyota family — and ARB Safari offers a matching snorkel for each of those vehicles.

ARB Safari Snorkels for the Toyota & Lexus 4x4 Family

If your driveway has more than one Toyota or Lexus 4x4, ARB Safari likely covers all of them. The table below compares the LX470/100 Series Armax against the other in-stock ARB Safari snorkels we carry at NLP Performance — including the Gen-4 4Runner that runs the same 4.7L V8. Prices and fitment are current at the time of writing.

ARB Safari V-Spec — Gen-4 Toyota 4Runner 4.7L V8

Running the same 2UZ-FE V8 as the LX470, the 2003–2009 4Runner gets a V-Spec snorkel that keeps factory airflow while adding full wading and dust protection.

ARB Safari Armax — Gen-5 Toyota 4Runner 4.0L V6

For the 2010-and-up 4Runner with the 1GR-FE 4.0L V6, the Armax body brings the same 25–70% airflow advantage as the LX470 part.

ARB Safari V-Spec — Toyota FJ Cruiser 4.0L V6

The FJ Cruiser's V-Spec snorkel is one of the most popular overland upgrades for the platform, raising the 4.0L V6's intake for confident water crossings.

ARB Safari R-Spec — 80 Series Land Cruiser

For the classic 80 Series Land Cruiser with the 1FZ-FE 4.5L inline-six (about 212 horsepower and 275 lb-ft in US FZJ80 trim), the R-Spec snorkel is the proven, value-priced answer at $399.95.

How Hard Is It to Install an ARB Safari Snorkel?

A typical ARB Safari snorkel install takes about 3 to 4 hours for a confident DIYer, though ARB's instructions quote roughly 70 minutes. Every kit is vehicle-specific and ships with a paper drilling template that locates each hole precisely. You will need a hole saw (about 4-1/8 in. / 105 mm for the body outlet), a stepped drill bit for the mounting holes, a pilot drill, and basic hand tools.

The most important thing to understand: installation requires drilling through the front fender, so it is not reversible once you cut. Many builders use 3M VHB tape on the A-pillar bracket to avoid drilling the windshield pillar, but the fender outlet still has to be cut. If you would rather not drill your own LX470, our team in Tampa, FL installs snorkels and full overland kits in-house.

Water Crossing Safety: What a Snorkel Does and Doesn't Do

A snorkel raises your air intake, but it does not make your truck submersible. It is one part of a sealed water-crossing setup. For deeper crossings you also want extended breathers on the differentials, transfer case, and transmission — a hot diff dropped into cold water can suck moisture in through a low factory breather. Pay attention to electrical connectors and the ECU as well.

When you cross, go slow and steady to push a controlled bow wave ahead of the truck, which actually lowers the water level around the engine bay. Many drivers also rotate the air ram head to face forward for maximum airflow, or rearward in heavy rain and dust to limit ingestion — a common field practice rather than a published ARB setting. The goal is simple: keep water out of the engine and the driveline.
