aFe Silver Bullet Throttle Body Spacer for Select 2003-2009 Lexus & Toyota (V8-4.7L) 46-38004

Fits select 2003-2009 Lexus GX470, LX470 and Toyota 4Runner, Land Cruiser, Sequoia, and Tundra (V8-4.7L).

The aFe Power Silver Bullet throttle body spacer is engineered to improve low-end torque and throttle response by optimizing the airflow as it enters the intake manifold. This spacer features a unique serrated/helix entry design that creates a turbulent vortex, helping the air-fuel mixture atomize more effectively. This specific design is also crafted to eliminate the high-pitched whistling sound often associated with traditional helix-only throttle spacers.

Precision CNC-machined from T-6061 billet aluminum, the Silver Bullet provides a durable, heat-resistant seal between the throttle body and the manifold. This is a straightforward bolt-on upgrade that utilizes factory mounting points and is compatible with both stock and aFe Power intake systems.
