Holley EFI Billet Racing 105mm Throttle Bodies Available For Race-Only Engines
These billet throttle bodies feature a robust, non-contact magnetic TPS sensor for smooth, consistent throttle operation and throttle response. The mono-blade itself is held to the throttle shaft with four profiled screws TIG-welded for maximum strength. The throttle shaft rides on roller bearings for equally smooth operation, and the throttle lever is "clockable" for multiple installation options. These have no provision for PCV – they're designed specifically for full-on race applications where every single horsepower counts. These lightweight CNC-machined billet throttle bodies have a 3.5-inch square bolt pattern with a laser-etched Holley EFI logo and are a perfect match for Holley EFI racing manifolds and custom fabricated applications.
