Will the K&N CAI throw a check engine light?

[Dirtydan]

I also have the polished typhoon in about 1,500 miles .... And knock on wood no issues to report....

my K&N typhoon has not thrown one cel light since install. all depends on how and who installs your intake.

That was me. Mine would throw a CEL ever 2-4 days. But this was after I had it on for 20someoddthousand miles and performing flawlessly during that time. After numerous trips to the dealer, the cause was the intake. No idea still what went wrong. But sure enough, took it off, went stock, and the problems gone. No biggie, I sold the intake for parts to a friend and I'm getting a Vararam.

Edit - want to throw this out there as well. Pretty sure my intake issues were a fluke. I loved this intake when I had it in. I've had K&N intakes in all my previous cars, as well as I suggested and installed it in my dads 2SS. I still recommend K&N stuff.

so if the check engine light comes on after putting a CAI on, how do I make the CEL go away

You need to get a simple car scanner (at any local auto parts store) and clear the code. Good idea to have one in general anyway.

It may or may not come back, if it does you'll probably need to clean the MAF sensor. If that don't work, dump K&N for something better. I say go with CAI, I love mine.
