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.\nSilver Bullet Throttle Body Spacer Kit GM Colorado\/Canyon 04-06 L5-3.5L\/07-12 L5-3.7L\n\u003cul\u003e\n  \u003cli\u003eSilver 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.\u003c\/li\u003e\n  \u003cli\u003eSerrated-Helix design improves venturi effect and reduces whistle\u003c\/li\u003e\n  \u003cli\u003eIncreases Air Speed, Improving Performance and Throttle Response\u003c\/li\u003e\n  \u003cli\u003eCNC-Machined from Durable 6061-T6 Billet Aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 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.
