King Motorsports 64mm DBW Throttle Body "Exchange"

Stock 06+ Civic Si Throttle Bodies measure approx. 60mm at the throat and 63mm at the entries. King Motorsports offers a service that will punch it out to a whopping 64mm straight through!! The 4mm increase has been proven to make 2-3hp below 6,000 rpm and a hard to beat 4.5hp average from 6,000 rpm and on... Consistent torque increase of 3-5 lb.ft. across the rev range on a completely stock vehicle!! 

We have a few cores on the shelf to help and alleviate the down-time associated with sending your throttle body in for our Boring Service. This is a bolt-on affair and can now be made with zero down time!! Simple install and absolutely the best bang for your buck.

Exchange only available when cores are in stock. If the core is out at the time of your order you will be contacted and be placed on a short waiting list. If you rather not wait and you dont mind the vehicle down time you are welcome to send yours in for same prompt service.

KMS Throttle Body Boring Service is only $175.00 with a refundable core charge of $300.00 if you chose to do the exchange. Credit will be applied once we confirm the return of a working core.
