aFe 07-13 Chevrolet Silverado 1500/GMC Sierra 1500 Silver Bullet Throttle Body Spacer - Silver 2016-toyota-highlander-le-esi6806218 This extension pipe is usedThe 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,
