they claim 18 hp and up to 40 lbs torque. is this true??? anyone notice a difference??
be honest.

 

I put a air raid cold air intake system and noticed performance increase. You can also hear the difference

 

grey hemi I am glad to hear it. i will have to order one. Did you install yourself? I installed a k+N in an old bronco but ha dto change the thermostat and the fuel rail etc... beyond me so brought to a mechanic. Do you need all that in the new setups or just the intake?
