Welcome To OCPerformance Parts LLC.

DBW adapters and old school air horns are in stock and were designed for OEM car throttle bodies and a ported Modern Muscle Xtreme 85mm throttle body. The lower adapter plate can be used for a stock truck throttle body but will have less hood clearance and the air horn adapter will not work with them. 

 Above: Just the lower adapter plate can be purchased separately. Please check my "Kits, Parts, and Pricing" page for a list of contents and pricing.

The IAT is integrated into the air horn for a simple easy no drilling or cutting installation. All you need to do is supply the car style IAT and install it into the boss with the supplied seal and snap ring!

 Above: This is the entire old school air cleaner adapter kit with hardware included. (No IAT is included but can be purchased at any Chrysler dealer.)
