Finally the best RBC Adaptor ever created. The K-Tuned Dual 62/70mm RBC adaptor has a unique press fit 7.5mm ring that allows the use of either a stock 62.5mm throttle body or a larger aftermarket 70mm unit. If you decide to upgrade to a larger 70mm aftermarket throttlebody later on, simply press out the ring and install the adapter. This kit comes complete with hardware for both 62.5mm and 70mm throttle bodies, so again it wil work if you decide to upgrade later on. 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?
