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.

1997 F350 8ft crew 7.5 gasser auto, single wheel, pulls 8000lbs of toy hauler and firewood. Only add is a B&M Trans Switch assembly and a multi quart trans pan and lil dents and scratches all the kids swear makes it faster now dad. The truck has 100k miles and we just installed new fuel pumps it needed she was still not acting like a big block motor, had torque but just wasent producing that big block  power we all expect. After installing the C.A.R.B. Approved K&N 52-2516 FIPK and replacing the stock muffler with a 2 chamber (Brand) we now feel it performs better than when it was new. The increased throttle response and report really WOWED us and she pulls like never before, we just couldn't be happier. DO NOT be the ********* we were and try the metric nut on the sae stud located on the filters chrome end, the sae nut is included and a quick check before wrenching is all it takes for a very clean and sturdy install. Check the 4 mass air flow adapter plate nuts and bolts the filter mounts to also, as we found they loosened up when the new assembly went through several heat cycles, once retightened they have remained in spec. We would indeed recommend this kit to any 460 gas drivers out there to spice up the performance and sound of their old ford. We are indeed considering the blue pre filter to spice up under the hood and prolong the filter use between servicing. What more can be said except, have you ordered it yet? no, why not. lol
