So, what are the benfits of a K&N Air Filter on my 2007 6i? (2.3L I4)
Would it gain any hp or mpg?

Also, how much horsepower would a nice, 6 or 8 psi turbo kit add to my car?

Thanks

I would guess for a turbo at 6 to 8 psi, you would be looking at 60-70 horsepower gain, but there is a lot of money and work to go into turbo'ing an N/A car, tunes, electronic sensors, lots of things like that, plus the basic cost of the turbo kit and the cost of dyno time. There are a few on here that are running turbos, I would contact them, they could give you a lot better details about it.

The benifits of the K&N is better air and more of it, but I doubt you will feel any difference, but it might get you 1 mpg in mileage, if you really want to add some power, get a nice cold air intake, it will be kinda pricey, but its worth it, adds to the feel of the car and got me almost 4 mpg.

there's no way you can guess what kind of gain your talking about without alot more info, such as what kind of turbo? if its a mitsu 9a pushing 8 psi, u might get 40 horse. and it its a big o holset turbo, u would be well over 100 horse gain. it all depends on the set up.

and asking something that broad with no info, means building a turbo set up is probably well beyond you.

I bought the k&n CAI for my 08' 6i and the paperwork that came with it said that you'd get 10-13hp and 1-3mpg from it. Though the hp benifits didnt start till in 3000+ rpm range.
