Issues with new K&N typhoon
So this might be a dumb question. first time posting and just in need of some general feedback. just installed a new CAI for my v6. first day everything was fine till after about 20 miles then CEL came on. At first I wasn't sure what it was. until later I found out with the autocal tool I got from overkill that I could check the codes. saw P0171 and P0174. Worked on my car earlier and disconnected the battery. Negative only. I took off the whole intake to make sure everything was placed correctly and fitted properly. looked for any air leaks but nothing.. reconnected battery and CEL was clear. took it for a test drive and again within 25-30 miles CEL came back on. At this point maybe its obvious I need a retune for the K&N typhoon. Not sure if anyone else has had this problem.

Just a thought... get yourself some mass airflow sensor cleaner and clean the entire throttle body, sensor, and upper intake manifold. See if the codes come back on after the reset then.

if it's lean bank #2 ... this is a common code thrown from allowing air to leak into the intake after the maf or from more air passing the maf than it's calibrated for.
Common issue with intake bridges that do away with the air straighteners (assuming they stuck to stock diameter). Leaky catch cans can also cause this. But you may just be SoL ...some cars are just very finicky about maf calibration and dont do well with after market intakes that modify the bridge. You'll need either a tune or revert to drop-in filters only to avoid having that code appear periodically. |

Just an FYI, but I had installed the K&N Typhoon on my 2018 RS a couple months ago and after 1k miles no issues. I did however replace the exhaust with the Borla ATAK quad-tips at the same time, so this might be keeping myself CEL-free with no tune. Just a thought if you are deciding to replace the exhaust as well.
