Hey, guys, I have a 2013 Honda Fit sport and recently installed a K&N CAI and unfortunately after lots of research along with trial and error I had to put the stock intake back in. The K&N CAI set off the check engine light without any vacuum leaks or problems with MAF. I also tried resetting the ECU however the code kept coming on. It was a lean code by the way. I saw online that a lot of people with honda fits experienced the same problem and one guy said he even called K&N and they acknowledged that this does happen with some installations and you can't do anything about it. As soon as I put the stock intake back in the code went away and hasn't come back. However, I still want to put a CAI in my car I was thinking about maybe a Takeda or Injen. Does anyone have a suggestion for CAIs that don't cause this check engine light?

 

I'm running the Japanese Top Fuel Zero-1000 Power Chamber on mine.

 

I’m running the Injen cia and haven’t had an issue once.
