K&N "Cold Air" Rehash

[SimonP5150]

All -

I wanted to share my experience with the K&N Intake for our cars, it has been both enjoyable and frustrating with the result being it got traded for a shift kit yesterday.

The thing makes a 996 really sound like the super car that it is but after 3 soiled MAF's I'm over it. I thought that it might be over oiling, so I stuck a dry cone on it and still killed another MAF in short order.

My observations:

1. The cheap MAF's hold up to hot air just as long as the Bosch units.

2. A bad MAF can throw all kinds of weird codes. Go clean yours.

3. It sounds great, mashing the gas in a tunnel always brings a smile to my face.

4. Car wants to die with the rain sock on the filter when driving through a touchless car wash.

5. Car runs like crap on hot days.

6. My opinion is that the car sucking hot air frys the MAF. I used a white cloth to wipe the inside of the intake tube around the MAF and there was no oil residue or dirt which is why I think it's the hot air that damages the MAF.

7. Removed hot air intake, replaced factory airbox, used lightly oiled K&N drop in, sealed off the small silencer hole with the Schnell pipe. Car runs great, sounds half as good but no more trouble codes!

Hmm, I have the K&N setup and so far, no issues. But colder climate here, maybe thats helping. I did clean the MAF the other day and noticed no difference, so think its OK. I will be watching this with interest to see if yours is the common experience. If it is I guess its back to the standard air box as well...

I have had the K&N for about 6 years now. I put on about 30K miles on it before turning it into a track car, and no MAF issues execpt for a problem due to an engine blowout at a track. :huh:

That being said, I personally don't think there's any real HP gains on the K&N, but I do love the engine sound with it, so it's worth the expense just for that.

Make sure there's barely any oil on it, it should be a very fine mist covering it when you clean it, as the oil will ruin the MAF.

Two+ years on the K&N, replaced the water-sock once. No problems with it.
