1. If i were to invest in a plenum what kind of results would i be lookin at and how difficult is it to put this in the car?

2. Basically i want to know the same things as the first question but about under drive pullies.

Thanks for your help

I noticed a LITTLE bit increase with UDP's and installation was pretty straightforward.

didn't really notice anything with the plenum...maybe a tad more throttle response. the plenum is very easy to install...

if you plan on going supercharged you can't have underdrive pullies though...but a plenum will deff help you

Is that something i can install fairly easily? would it take away my highway driving?
