The AEM cold air intake will probably be your best bet if you want more sound.

It might throw your fuel trims off though - that does occasionally happen with CAIs.

Probably the exact same until you reach the pcv inlet. Someone with alot of time on their hands could probably make it work.

Somewhat.

Well, it's more of a short-ram, so the air won't be that much colder - but the open filter will be much louder. There was a thread on here and a few members got one - but I never got a solid answer as to how fuel economy was affected - some SRIs increase fuel economy as they'll draw warmer air in from the engine bay.

As far as K&N vs AEM - they're the same company now, so it's really a preference of filter.

I had it on ours for a month, got a check engine light. code was p0171. Put it back to stock and took it to the dealership. Said they couldn't find anything wrong and the code cleared itself while they had it. I'll be putting it back on in a couple days to see if the code comes back or if it was coincidence. Hopefully it was a coincidence, because it really does sound good.

Doubt it was coincidence, as that is a lean code - common with CAIs. Definitely related.
