aFe Silver Bullet Throttle Body Spacer for 2004-2012 GM Colorado and Canyon L5 3.5L/3.7L | 46-34018

The serrated/helix design creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber, resulting in increased performance and improved throttle response. The serrated/helix combination design also reduces intake whistle that occurs with helix-only designs (US PAT 07055513). This Silver Bullet throttle body spacer is precision machined from 6061-T6 billet aluminum for lightweight, high strength, and perfect fit and finish. Its black anodized finish gives a stealthy look. Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed, performance and improve throttle response. This Silver Bullet throttle body spacer uses all factory mounting locations, making for a hassle-free installation. A supplied gasket provides a perfect seal. Silver Bullet Throttle Body Spacer Kit GM Colorado/Canyon 04-06 L5-3.5L/07-12 L5-3.7L

• Silver Bullet throttle body spacers create turbulence in the air flow at the point just before entry to the engine – increasing performance, as well as improving throttle response and fuel efficiency.
• Serrated-Helix design improves venturi effect and reduces whistle
• Increases Air Speed, Improving Performance and Throttle Response
• CNC-Machined from Durable 6061-T6 Billet Aluminum

The aFe Silver Bullet Throttle Body Spacer is designed for select 2004-2012 Chevrolet Colorado, GMC Canyon, and 2006 Isuzu i-350 models equipped with L5 3.5L or 3.7L engines. Its serrated-helix design creates controlled turbulence in the intake manifold, helping increase air speed and improve throttle response. The combination of serrated and helix surfaces also helps reduce the intake whistle commonly associated with helix-only spacers.

Precision CNC-machined from lightweight, high-strength 6061-T6 billet aluminum, this aFe throttle body spacer delivers a durable construction and precise fit. The black anodized finish provides a discreet appearance while adding surface protection. By lengthening the intake track, the spacer is designed to support improved airflow characteristics, engine performance, and fuel efficiency. It uses factory mounting locations for a straightforward installation, and the included gasket helps provide a reliable seal.

This product is intended for off-road or competition use where applicable and is not CARB approved. Verify vehicle application and local emissions requirements before installation. Compatible fitment includes the 2004-2006 Chevrolet Colorado and GMC Canyon with the 3.5L L5 engine, the 2007-2012 Chevrolet Colorado and GMC Canyon with the 3.7L L5 engine, and the 2006 Isuzu i-350 with the applicable 3.5L L5 engine.
