On a stock motor you wouldnt see big gains just have some bling under the hood thats all..


the only gain from this I see on a stock or close to stock car is the ability to tap the drivers side rear and install a fitting to allow coolant to flow back to the crossover in the front... or atleast connect it to the passenger side hose that goes to the heater core.

this will eliminate the 2 hot cylinders on the drivers side rear and allow you to run a more agressive tune. of couse a S/C or nitrous car would benefit greatly from that alone.

They posted 25hp gain.. with tb/plenum on a fully built high-compression motor with cams, heads, etc etc... In all reality it gained about 7rwhp.. totally NOT worth the money
+1 I totally agree that for the gain it is NOT WORTH IT.
To bad it's made in China. :notnice:
