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. This item will only fit models equipped with the factory intake system.\nSilver Bullet Throttle Body Spacer Kit Honda Civic Si 06-11 L4-2.0L\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\u003eWill only fit models equipped with the factory intake system\u003c\/li\u003e\n  \u003cli\u003eCNC-Machined from Durable 6061-T6 Billet Aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eImprove intake airflow and throttle response with the aFe Silver Bullet Throttle Body Spacer Kit, part number 46-37006, designed for the 2006-2011 Honda Civic Si equipped with the factory intake system. Its serrated-helix design creates controlled turbulence at the throttle body, helping increase air speed and intake pressure as the air enters the combustion chamber. The result is sharper throttle response, improved engine performance, and potential fuel-efficiency benefits.\u003c\/p\u003e\n\n\u003cp\u003eThe serrated and helix combination is engineered to enhance the venturi effect while reducing the intake whistle commonly associated with helix-only spacer designs.
