| VORTEX RAM AIR INDUCTION SYSTEM FOR H2 |
|
BREATHLESS PERFORMANCE PRODUCTS- This vortex rammer kit replaces the restrictive stock air box assembly. Look closely at the filter and note that this is not the K&N filter that everyone sells. This revolutionary lifetime air cleaner contains an internal vortex velocity stack. It obtains cool pressurized air from the side fender and through our revolutionary custom Induction Towers. Our specially designed induction towers takes cool air from over the top of the hood, through our stainless steel mesh opening then forces it into our rammer box, where in turn, it directly injects cold air into your intake. (Lowering Manifold Air Temperature by almost 20 Degrees) This system can be used with or without the custom ram towers. Benefit of the towers are to force additional cool air from above the hood into the air box. Silicone couplers come in assorted colors: Blue, Red or Yellow Remember, cold air means more power.

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.
