aFe Power Silver Bullet Throttle Body Spacer for 1999-2007 GM Trucks & SUVs (6.0L) 46-34001

The aFe Power Silver Bullet throttle body spacer is engineered to optimize the air-fuel charge for improved combustion efficiency and throttle response. This precision-machined spacer fits select 1999-2007 GM trucks and SUVs (6.0L), including Chevrolet Silverado, Tahoe, and Suburban, GMC Sierra and Yukon, Cadillac Escalade, and Hummer H2.

Constructed from durable T-6061 billet aluminum, the Silver Bullet uses a unique serrated/helix entry design. This specialized geometry creates turbulence in the intake manifold just before entry into the engine, increasing air volume and improving low-to-mid range torque. Unlike standard helix spacers, this design is specifically tuned to eliminate the high-pitched whistling sound often associated with throttle body spacers.
