CNC Billet Aluminum Throttle Body Spacer Kit | GM 4.8L, 5.3L, 6.0L, 6.2L V8 (2007–2013)

Optimize Your Intake Airflow for Better Throttle Response and Low-End Torque.

Looking for an easy, cost-effective way to wring a bit more efficiency and crisp throttle response out of your V8 truck or SUV? Our Premium CNC-Machined Throttle Body Spacer Kit is designed to optimize your intake tract. By slightly extending the distance between your throttle body and the intake manifold, this spacer increases the total plenum volume and optimizes air velocity entering the engine, helping your vehicle breathe better.

Precision-engineered from top-tier materials, this kit features an integrated high-temperature silicone seal to eliminate the risk of vacuum leaks. Accompanied by rigorously tested stainless steel hardware, it offers a perfect factory fit and long-lasting durability that stands up to severe engine bay heat and harsh driving conditions.
