Gen 3 Reische Thermostat

The newest generation of the Ford-4D thermostat (yes, the '96-04 Cobra fitment!) carries even more improvements!
Check it out.. now it has a rubberized diaphragm, larger heat motor, and improved cooling efficiency.

These are in stock at Lethal... follow the link here!

I installed a Stant Super Stant 180 degree #46138, its designated for the 03/04 cobra but fits my 01, its a quality piece and has worked great for me. The Super Stats have really good reviews . They sell for around $15, it looks the same as the lethal performance one thats in their VERY LARGE PHOTO, I didnt have to tune for the 180 but with Lethals 170 it might be needed.
