2003 H2 Hummer Coolant Bypass Tube

Item 400-216: H2 Coolant Bypass Kit

COOLANT BY-PASS KIT

Breathless Performance Products – Your factory unit passes coolant through the throttle body, thus produces less horsepower. Our coolant By-pass (item# 200-216) kit eliminates the passing of the coolant through the throttle body, which keeps incoming air temperature cooler and provides more horsepower.

NOTE: Colder Days produce faster cars.

Install only on a cold engine....

Underneath the throttle body there are 2 coolant lines, one comes from the radiator and the other from the intake manifold. Remove the lines that enter the throttle body and mate them together with the bypass tube.

PRICE: $19.99
