LS1 Throttlebody Water Bypass Kit-GM cars circulate hot coolant through the throttlebody to prevent throttle blade icing in cold climate conditions. While this works great for it's intended purpose, not many of us drive our F-Bodies in the snow much! The cooler and denser the incoming air, the more power the engine can create. This kit allows you to bypass your throttlebody coolant passage to keep your incoming air as cool as possible. Save yourself the hassle of locating the hardware and use this pre-made kit instead. Includes billet aluminum adaptor, hose clamps and rubber dust caps to keep the throttlebody coolant passage clean if converted back later.
