The Legendary Blow-By Racing Custom
2005-2010 GT-500 Throttle Body Adapter Plate

This cleverly-engineered plate is an easy bolt-on that
provides dyno-proven gains in both horsepower and torque.
And you can only get it here at Blow-By Racing!

Simple Bolt-on - Installs in 10 minutes


Our plate is different from those offered by the competition in that our 1/2" thick adapter plate is engineered to exactly match the center of the throttle body bores with the center of the bores in the factory 4.6 3V intake manifold.

This task required very careful measuring, design, and five-axis machining. But the end result is a smooth, tapered transition from the large Shelby GT500 throttle body to the factory intake manifold mounting flange. The adapter plate is machined for the included OEM-style seal for a factory-like installation.

This plate includes a five-axis CNC-machined billet adapter plate, billet mounting bolt bushings, and stainless steel mounting bolts.

A factory GT500 throttle body is required for complete installation. We do sell a complete kit that is ready to go!

This plate is an easy way to add power and it installs in just minutes. Independent tests have shown gains of over 10 HP at the wheels. A must-have for any 3V Mustang owner!

Accept no Substitutes or Imitations!

Note 1: The billet adapter plate is also available with an tapped NPT hole on the side of the plate for applications with nitrous injection. Please call for details and availability.

Note 2: The large opening of this throttle body requires an inlet boot that will stretch to 5". The stock Ford boot will not fit, although the inlet boots included with many aftermarket air intake kits will fit. If needed, a black silicone transition hose (5" to 4.5", 3" long) is available from us for $20 to adapt this throttle body to your air intake system. Please call for availability.
