Cardinals Racing throttle bodies have a smooth polished internal surface to further improve your engine air intake flow. Performance throttle body upgrades are important for EFi Fuel injected motorcycles, just like carburetors were for older bikes. If you have a big bore kit or cylinder head/big valve upgrade to your motor, this is a must for supporting mods.
