aFe Momentum GT Cold Air Intake - Lexus GX 550 (TJA80) - 3.4L Twin Turbo V6
The aFe Momentum GT is a twin sealed cold air intake for the Lexus GX 550 and its 3.4L twin-turbo V6. Two one-piece sealed housings in heat-resistant XLPE (cross-linked polyethylene) replace the factory airbox, each with a clear sight window so you can check the filters without taking anything apart. Twin computer-designed, dyno-tuned tubes feed the turbos.

How to install the aFe Momentum GT intake on the Lexus GX 550
Each housing holds an 8-inch tall radial-flow filter on a 3-inch flange, with expanded metal for impact protection. aFe measures 500 CFM with the Pro 5R filters, 47% more than the factory intake, and aFe's dyno testing shows up to +13 kW (+18 hp) and +30 Nm.
Options: Pro DRY S uses dry, oil-free three-layer synthetic media that you wash and refit without oiling; aFe quotes up to +12 kW (+16 hp) and +27 Nm (+20 lb-ft), with 41% more airflow. Pro 5R uses oiled five-layer cotton gauze media for the most airflow and usually the biggest gains; up to +13 kW (+18 hp) and +30 Nm (+22 lb-ft), with 47% more airflow.
Note: Suits the Lexus GX 550 (TJA80) with the 3.4L twin-turbo V6. Installation by a professional is recommended.
