K&N 57i Performance Induction Kits

[ZVH]

I have a Saab 9 3 2006 5spd manual.
I would like to install a K&N 57-0641.

Few questions

Does it net the horsepower it claims?
Does it fit on American models? (says non-us in info)
Is there something better?

Thank you.

Hi and welcome to TorqueCars. Your post got held in the moderation queue because you include a link and have less than 10 posts. No worries, I've authorised it for you.

Power gains on induction kits tend to be around the top end of the rev range. I would always recommend getting a cold air feed as well as the under bonnet temps will rob you of power.

I guess that the intake pipe size is different on American models so the kit will probably not fit unless you get an adapter for the pipe.

BMC carbon filter boxes get quite good power gains and don't sound as harsh as an induction kit but it is probably the induction noise you are after.

Thank you.
I am after power gain, although I bit of throttle noise would be nice.
I will check out the BMC filters. Are they Comparable to the K&N replacement filter?

Yes, the BMC tend to come in a closed box so are less prone to the problems of sucking in hot engine bay air. They don't make quite as much noise but it is a good setup none the less.
