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. It features a black anodized finish. 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 Black Toyota Corolla 19-26 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\u003eUnique Serrated\/Helix Entry Design Creates Turbulence and Reduces Whistle Sound\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  \u003cli\u003eDyno-Proven Gains up to +3 HP \u0026amp; +3 Lbs. x Ft.

Designed for select 2019-2021 Toyota Corolla and 2019-2020 Lexus UX200 models equipped with the 2.0L four-cylinder engine, this spacer uses a serrated and helix entry design to create controlled air turbulence immediately before the throttle body.
