aFe 50-70124R Momentum GT Pro 5R Dual Intake for 2024-2025 Lexus GX550 V6-3.4L

Vehicle Fitment

• 2024-2025 Lexus GX550, V6-3.4L (tt) - All trims (Premium, Premium+, Luxury, Luxury+, Overtrail, Overtrail+), 4WD

Fitment Notes

• The Lexus GX550 is exclusively 4WD - all supported model years and trims use the same twin-turbocharged V6-3.4L (V35A-FTS) engine and intake architecture.
• This is a dual intake system - one complete filter and housing assembly per turbocharger inlet - engineered specifically for the twin-turbo V6 layout of the GX550 platform.
• Direct bolt-on installation using factory mounting locations - no cutting or modifications required.
• This product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles.

Features

• Momentum GT dual cold air intake system purpose-built for the 2024-2025 Lexus GX550 equipped with the twin-turbocharged V6-3.4L (V35A-FTS) engine.
• Dyno-proven gains of +16 HP and +20 lbs. x ft. TQ over the factory intake system.
• Dual Pro 5R air filters - five layers of progressively finer pre-oiled cotton gauze - one per turbocharger inlet - delivering the maximum airflow and highest power gains available in the Momentum GT filter lineup.
• Each filter measures 8" tall with a 3" flange and inverted top for maximum filter surface area, extended service intervals, and impact-resistant expanded metal protection.
• Dual one-piece sealed XLPE (cross-linked polyethylene) housings - heat-soak resistant, minimizing intake air temperatures by isolating the charge air from engine bay heat.
• Two large clear sight windows - one per housing - enable convenient filter inspection at any time without removing or disassembling the system.
• Dual dyno-tuned XLPE intake tubes - computer-designed for maximum power gains while maintaining precise factory fitment on the GX550 platform.
• Patent-pending filter-to-housing interface minimizes total part count for a fast and straightforward installation process.
• High-quality premium clamps and silicone bellows couplings provide a secure, durable, and flexible connection throughout the dual intake path.
• Fewer parts than competing systems - Momentum GT intakes are designed for quick, hassle-free installation without compromise.
• Engineered and manufactured at aFe POWER's Corona, California facility.

Product Description

The aFe POWER Momentum GT Cold Air Intake System with Pro 5R Filters (PN 50-70124R) is a dual intake upgrade engineered specifically for the 2024-2025 Lexus GX550 equipped with the twin-turbocharged V6-3.4L (V35A-FTS) engine. Because the GX550's twin-turbo architecture feeds each turbocharger through its own dedicated air inlet, this system includes two complete filter-and-housing assemblies - one for each inlet - creating a fully optimized, symmetrical intake path from the ambient air inlet to both turbocharger compressor housings. The result is dyno-proven gains of +16 HP and +20 lbs. x ft. of torque over the restrictive factory airbox, delivered without any ECU recalibration requirements.

Each of the two Pro 5R filters measures 8" tall with a 360-degree radial flow design, 3" flange, and inverted top that maximizes filter surface area within the housing for longer service intervals between cleanings. The five-layer progressive cotton gauze media - pre-oiled from the factory - provides exceptional airflow combined with thorough particle filtration, and the expanded metal construction offers structural protection against debris impact. Unlike paper filters, both Pro 5R filters are washable and reusable with standard aFe cleaning and re-oiling kits, eliminating recurring replacement costs. The dual sealed XLPE housings are constructed from heat-soak resistant cross-linked polyethylene and each feature a large clear sight window, allowing both filters to be visually inspected at any time without disassembling any component of the system.

Installation uses all factory mounting locations with no cutting or modification required. The dual dyno-tuned XLPE intake tubes are computer-designed for precise fitment on the GX550 platform, and high-quality clamps and silicone bellows couplings provide a secure, leak-free connection at every junction. The Lexus GX550 is exclusively 4WD across all trim levels - Premium, Premium+, Luxury, Luxury+, Overtrail, and Overtrail+ - and all share the same twin-turbo V6-3.4L architecture, making this system a confirmed fit for the full lineup. This product is not currently CARB exempt and cannot be sold into California. Built to aFe POWER's exacting standards and manufactured at their Corona, California facility, the Momentum GT Pro 5R dual intake is the proven high-performance intake upgrade for GX550 owners who want maximum power extraction from their twin-turbo V6 with a straightforward, direct bolt-on installation.
