The increased horsepower my car has now makes the enjoyment of driving a Porsche that much more exciting. The sound that comes from the engine now is awesome. I recommend a K&N 57 Series FIPK Air Intake system to everyone out there that wants to experience more from what their motor can do.

Grab a few extra ponies with a CARB legal air intake from K&N. Great look for a good price and it's good quality from K&N. The installation wasn't too bad but could be a bit clearer for us that don't do this everyday.

Very Well Made!

I was looking to replace a part on my Porsche Carrera ... and this was the perfect fitting part. The part arrived in perfect condition and was exactly as advertised.

Assembly was pretty clear. Take care when you align the intake to the existing seal located on the lid. Also, the hose for the vacuum (auto trans) is the incorrect diameter. It comes with 1/2 inch diameter should be 3/8 inch. Use a little oil and effort to push the angle fitting which comes with the kit into the 3/8 inch holes - tight fit. The large diameter hose clamps used to clamp the rubber adapter to the throttle body was also too small- use the ones taken off the vehicle.

not too bad

It was not easy to install...but once you take a look at it and take your time it was not that bad.

Intake installation wasn't really straightforward because the hardware isn't referenced very well in the instructions... Most steps have install X using the hardware provided but doesn't really say what bolt size or washer/nut should be used. Besides that... install wasn't that bad. You can definitely here it around 5k rpm and up. I felt like it made my car a little faster and it seemed like it had better throttle response on higher RPMs.

A Product Worth Purchasing

The K&N Cold Air Intake produces what it promises = increased horse power. The directions were 37 steps long and one or two needed steps were missing. But, with help, it was installed in about 2 hours. I am very pleased with the performance.

The instructions supplied needed the visual renderings to be larger..also the schematic of the parts very poor!

Good product with so-so instructions.

This K&N filter set up fits nicely (although a tight fit in a 911). I wish the advertising said something about it's limited bad weather capability. Also regarding the instructions its awfully hard to follow which parts go with which steps so take your time. Don't face the air box bolts outward or you run the risk of them rubbling on the engines pulleys....the instructions don't say this. Overall it was ok and I am happy with it. The car now sounds even better than it did.
