Description
Part number SS450HP, the ARB® Safari ARMAX Snorkel, is a high-performance 4-inch air ram intake snorkel system designed specifically for the 2010–2023 Toyota 4Runner, relocating the engine’s air intake from under the hood to a safer, elevated position for a constant supply of cool, clean, dry air.
IMPORTANT: This snorkel is a vehicle-specific fitment designed exclusively for the 5th Generation Toyota 4Runner (2010–2023). Confirm your vehicle year and trim before purchasing. Engine coverage includes the 4.0L V6 GAS (all trims, 2010–2023) and the 2.7L L4 GAS (2010 SR5 only). This is the high-performance ARMAX model — verify this is the correct specification for your build before ordering.
The ARB® Safari ARMAX Snorkel SS450HP is a purpose-built intake relocation system that moves your engine’s air source from a low, vulnerable under-hood position to a significantly higher mounting point along the A-pillar. At this elevation, the intake draws from an area where air is consistently cleaner, cooler, and drier — protecting the engine from water ingestion during water crossings and from dust infiltration in harsh off-road conditions. The vehicle-specific design ensures a precise, factory-quality fit with no cutting or fabrication beyond the standard installation procedure.
The SS450HP is ARB’s® ARMAX high-performance model, featuring a 4-inch air ram intake head that delivers airflow capacity rated at 10 percent higher CFM than competing snorkel brands. This increased volumetric efficiency means the engine receives a more consistent and adequate air supply under demanding conditions — whether at low engine speeds on a technical trail or under sustained load on a highway run. The larger intake diameter and optimized air ram design reduce restriction across the entire intake path from intake head to airbox.
The snorkel body is manufactured from UV-stable cross-linked linear low-density polyethylene (LLDPE), a material selected for its exceptional impact resistance and long-term durability in outdoor environments. Unlike standard polyethylene, LLDPE maintains its structural integrity under sustained UV exposure without becoming brittle, fading significantly, or deforming. The snorkel ships in black and is designed and manufactured in Australia. All necessary fasteners and mounting brackets are included in the kit. ARB® backs this product with a lifetime warranty.
