Chevrolet Silverado / Tahoe / Suburban / Avalanche / SSR, GMC Sierra / Yukon, Cadillac Escalade & Hummer H2 Billet Aluminum Throttle Body Spacer 1999 - 2007 (4.8L / 5.3L / 6.0L / 8.1L V8)

Improve throttle response and low-end torque on your GM full-size truck or SUV with this premium billet aluminum throttle body spacer, precision CNC-machined from aircraft-grade 6061-T6 aluminum for permanent durability and proven performance benefits. The spacer installs between the throttle body and intake manifold, increasing the air volume in the intake plenum and creating an air swirl effect that improves air/fuel mixing for noticeable gains in low-end torque, throttle response, and fuel efficiency under light-throttle driving. The integrated original silicon seal provides strong sealing performance with high-temperature and corrosion resistance, while the included 304 stainless steel mounting bolts (verified through 72-hour salt spray and 180-hour high-temperature testing) deliver reliable long-term clamping force in the harsh underhood environment.
