Product Description

The BBK 1517 Power Plus Series 65mm Throttle Body is a direct-fit performance upgrade engineered for 1986-1993 Ford 5.0L Fox Body and related EFI-equipped platforms. By replacing the restrictive factory 56mm throttle body with a free-flowing 65mm bore unit, this throttle body increases airflow by up to 30%, delivering measurable gains of 7-12 rear-wheel horsepower and improved throttle response across the RPM range. The 65mm bore is specifically sized to match the OEM intake manifold opening, making it the ideal upgrade for naturally aspirated builds running stock or mild configurations.

Construction starts with a high-quality 356 aluminum alloy casting, precision CNC machined to ensure a perfect OEM-quality fit every time. Internal components include double-sealed bearings, O-ringed throttle shafts, and die-stamped throttle linkages for long-lasting, rattle-free performance. Installation is straightforward - this throttle body reuses the factory gasket, retains all stock electronic components, and requires no tune. Note: EGR spacer plate BBK PN 1518 is required for EGR-equipped vehicles and is sold separately.
