ya they look cooler, might add a couple..an u might notice it will rev a little easier

 

I have a March Ram air on mine, I dont know how much of a difference it made, as it was there when I bought it. I heard its good for some power, and the system really shines at higher speeds, like anything over 75 I think. plus, it looks kinda kool with the vent under the bumper, people are always asking me what is for too bad mine has a chip in it from the previous owner[>:]

 

the udp's free up a few hp i ran the straight cai on mine replaced the march ram air that was on it seeing how the duct work and scoop was missing but i nocticed a gain on the car , the only thing bad that i have noticed is that my alternator has trouble keeping up now with the udp's , i went with the march polished alum.udp's on mine

 

Don't know how any of you are expecting to feel the difference.
The underdrives do free up power but the amount is so small you will need track times to notice them.
I'll bet they are less than 0.1 second and no can't feel that.

They are also nice for geared up cars. Since the engine is now reving higher at the same cruise speed. You don't force your accessories to spin faster too.

i have a throttle enhancer on mine also that could be where the diff is seeing how i have imediate response on the throttle .
