I asked the service guy at the dealer about how the CAI would effect the warrentty. He said putting it on will not void it, however, if the check engine light goes on, or the computer records any problem codes that they can prove is becuase of the intake change then they will refuse to fix any of the related issues.

He said bottom line, "it is up to me... 50-50 chance"

Keep in mind with the Magnusson - Moss act, the dealer has to PROVE that your modifications cause the issue they wont fix. However Many dealers will automatically point to the CAI if say a check engine light comes on, even if it has nothing to do with air intake into the engine. It could be something as simple as 1 cyl misfire from a bad plug wire, and they may claim check engine, you've modified the engine. You can always demand them to pull the code, and then discuss how it'* affected by the CAI..

It specifically says you can modify the product (in this case the car) and the original parts and work will still be warranted, not your modifications or problems from your modification.

I have also messed around with the idea of buying my own scan tool. From what I have seen, the are well worth the money to have. If I had one wouldn't I be able to check this information myself to see if the CAI was having any adverse effects before even taking it to the dealer?

And then swap the stock one on before you go if it does

the CAI will NOT cause any adverse affects.

the only possible way is if you break something installing it.. which is unlikely

which do you all recommend, standard CAI vs. FWI, and what if any, noticable difference in performance/sound is there betteween them? Also what company/maker? From what I have seen most seem to be running the Intense FWI...

Search may be your best bet...being that most saw and replied based on the K&N vs Fram title.

I guess we should differ this question about FWI and CAI to this new thread
