K&N FIPK Questions

[plirky]

With that CAI did u see any mileage increase?

I though I had an increase after installing mine last Nov (about .5-1 MPG). I know attribute that to cleaning the throttle body and MAF I did at the same time. My MPG had dropped back to about pre install levels, so I cleaned the Filter, TB, and MAF again last month, and see the .5-1 MPG gain again.

I do like the sound better though with the K&N FIPK; a little more growl. Also, I'm almost finished installing the DT headers and I'm going to upgrade the exhaust (header back; passenger side cat is bad, so why not) when finished. Looking for every bit of HP I can get Will be interesting to see MPG after.

Finished installing the K&N this morning and the sound is awesome under WOT. It also creates a lot of space under the hood for mounting other stuff (maybe ARB compressor?). Nice and quiet under idle. Love it.

I gotta say that the instructions were pretty crappy especially when it comes to the vent lines. I also think one of the provided new vent lines is too small to fit. Can others confirm this? One of the replacement tubes is supposed to go on a brass fitting on the engine that is probably 50% bigger than the tube. I tried for a long time to make the smaller tube fit on the larger brass fitting but I gave up and jury-rigged the old (existing) tube with the new one. It's ghetto but it works for now (no idiot lights). The picture in the K&N instructions seem to show a much smaller brass fitting. Was this changed at some point? My kit says 1999-2005.

The fitment of the 4th tube (the one you are suppose to re-use) to the K&N is also terrible and I really want to replace it with a new one.

Anyone else have these vent tube fitment issues?

Was the same for me. I ended up using a couple of adapters I found at part stores to make it work.

I definitely found a major problem with the K&N kit. The sound is so awesome at wide open throttle that there is no way your gas mileage will go up. It will actually go down.

From start to finish, how long did the installation take?

I think about 2.5 hours including trying to figure out what to do about the breather hoses. If I had to do another truck I could probably do it in just over an hour.
