Cold air intake

[Turbo_B5]

Hey I want to get a new cold air intake for my car 1997 a4 1.8T for the sound and better mileage. Was looking at http://www.knfilters.com/search/prod...x?prod=57-0282. Im wondering what yall run on your cars.

to see any performance gains your going to have to make a custom heatshield.

Either do the swiss cheese mod or get something with a velocity stack. Also, K&N filters can mess up your MAF. Ask me how I know. Go with an AEM.

oilless filters are important. Just make it, its better that way.

Definitely go with AEM DryFlo Filter. Of course, K&N owns the filter division of AEM anyways.... but still.

Here's how I did mine with a K&N and homemade heatshield.

I'll try to post a picture of my setup later, but here are the specs:

- AEM Filter, 6" inner flange diameter
- Blox 3" Velocity Stack (6" outer diameter)
- 3" 180* Silicone Bend (required some trimming)
- Evolution Racewerks Aluminum TIP
- Blinktek Heat Shield
- VR6 MAF housing (optional)

The piping goes: Filter/Velocity Stack -> 180* Bend -> MAF -> TIP. The velocity stack fits right into the filter and then the outlet of that fits into the 3" bend.

Obviously you can skip the 3" MAF if you aren't tuned for it but this setup works really well for me. The filter is HUGE but it just sort of tucks below the headlight. It took some trimming to fit the 180* hose and I actually trimmed a little too much so I will be replacing the hose in the future (maybe), but it seals so I'm happy. The velocity stack works to straighten out the airflow before hitting the MAF and although the 180* bend may undo a little bit of that it hasn't been an issue. I ran a filter straight off the MAF before this and I had some strange boost behavior, including building boost too rapidly at light part throttle in low gears (eg I would come off of a red light with maybe 25% throttle and my boost would shoot up briefly to 5 or 10 psi and then drop back down to 0); changing to a velocity stack setup fixed it.

Skip the cold air intake, it is useless. Keep your stock airbox.

My set up, used heat tape to shield the intake

I just want to comment on the placement of the ICM when you guys are deleting the airbox. The ICM gets hot and thus Audi designed it to sit on top of the heatsink that's integrated into the airbox. Don't be surprised of a failure when removing the ICM from that heat sink and just having it sit there.

IMHO, fuck the ICM and delete that bitch using TFSI coil packs. No more failing ICM. And the coil packs, when they go bad, are like $20/ea.

No ICM = No problem. As RallyeBourne said, if you have it delete it. I have a 2000 so no ICM to worry about.

Here are some pictures of mine. I try to run the end of the snorkel but the heat shield makes it difficult. I plan on cutting out the top portion of the heat shield where it meets the snorkel so I can run it without issue.


I don't know if you can tell how big the filter is, but its friggin' huge, especially compared to my old AEM filter.

Out of curiosity, is there a reason you ran the u-bend, rather than having run straight like JJ.'s?

Getting ready to build mine, that's why I'm asking.

I originally had it running straight off the MAF and thats what I would have liked to do with the velocity stack but the size of the filter and the fact that the velocity stack "stem" sticks out a good 1.5 inches from the end of the filter flange made it impossible to fit. Like I said, the filter is huge compared to the one I was running before that did fit (this one) so the only way to fit it was with the U-bend. It may have something to do with my TIP since I'm using the ER aluminum one and the inlet (at the MAF) seems to sit a little closer to the firewall then stock, but I definitely couldn't fit it.

That's kind of what I figured, but wasn't completely sure. Thanks for clarifying!

Anyone got er tip still and willing to sell
