Finally the best RBC adaptor ever created. This is our 70mm RBC adaptor with a press fit 7.5mm ring. This allows you to use either your stock 62.5mm throttle body or a larger 70mm unit. If you decide to upgrade to a 70mm aftermarket throttle body, simply press out the ring and install it. This kit comes with hardware for both 62.5mm and 70mm throttle bodies. SO no matter what you decide to do later on, this RBC adaptor will work. If you want to go back to stock for whatever reason, press the ring back in and install your oem throttle body. The kit comes complete with all hardware and the RBC gasket, saving you $10 and a trip to the dealer. The ring has a very snug fit and will not move or leak when installed. How much better could this kit be?
