Does anyone use one on their Forester? Do they work? Also, I hear alot of back and forth on the CAI's , are they worth the money? Do they improve performance? Feedback please

They make more noise, but very little if any actual power. Most dyno results seem to indicate around 2hp, not really worth it on a cost/HP ratio but that doesn't stop people from buying them. The key is to get one that actually installs and pulls air in from the fender void. I see too many installed with the filter/inlet in the engine bay which is actually worse than the OEM design.

[email protected]'s show up more dirt in oil. Probably its not nearly enough to cause a problem.

before you buy a CAI and slap it on the Forester I'd suggest reading, http://www.subaruforester.org/vbulletin/f66/09-forester-air-intake-system-55321/#post710801

There's a link over to NASIOC with some really good data
