Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

They apparently have tested only on C2 996 3.6L H6.
Leading evidence: 'Test only' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Test only' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Oh yeah, if you use too much oil on the filter it could cause a problem with the MAF, or damage the MAF.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I am considering installing a K & N (57-7000) Performance Air Intake System and would like to hear from anyone who has experience with this or similar system to enhance air intake.
1. Does it work ?
2. My car is a 996 40th Anniv with no engine modification. K & N cannot tell me whether or not it will work on my car... They apparently have tested only on C2 996 3.6L H6.
3. Any other suggestions for performance enhancement ??
Thanks,
Fred Gorstein
You already have the X-51 dual intake air box on your 40th. IMO, CAI increases only the air intake sound and thereby the driver "thinks" it increased the HP. Some will say that the CAI will allow the engine to rev more freely, but even if that is true, that in itself does not add HP. Most CAI actually pull some of the air from the hot engine bay, unlike OEM. Some companies claim a 10 to 15 HP gain from just the CAI. If it was that easy, don't you think Porsche would have done this years ago? Oh yeah, if you use too much oil on the filter it could cause a problem with the MAF, or damage the MAF.
IMO, not a good bang for the buck, especially on a car with the X-51 package. Others may, and probably will, disagree.
X51 on the 40th only has single intake airbox...and I agree, air box mods don't do much other than sound. I think it's the 997 X51 with the dual intake air box.
