THROTTLE BODY BUTTERFLY VALVES 25-30MM

Throttle body butterfly valves

Fine tune your build with these multiple size throttle body valves. By machining out the inside diameter of your throttle body you can increase the air flow in 1mm increments to get your build just right. This modification requires you to have a lathe and some patience to get just right. We understand that this mod isn't for everyone and we do offer the machining service in house. For a custom built throttle body please check them out here or you can send yours in to be machined here.
