Customer Feedback

I must say that today I put on my K&N Filtercharger Kit on my 1987 Saab 900 Turbo, and I must say that I am in awe of the performance! It's like owning a new engine! RPM's pick up much faster, and it has a better top end now...I would guess that I have about 4-6 more hp! it's so great! You guys are definitely worth the money, I recommend you to everyone I know! Thanks for making such a quality product!

Again, THANKS!

I changed the filter on my 1997 Saab 900 Turbo to a K+N filter. The car already had an uprated ECU (220hp from 185hp). It has really made a difference to the performance. The peak power is slightly improved but the throttle response is dramatically quicker. I think I am seeing slightly better MPG as well.
