I have an Injen CAI
from years ago. I threw 2 Cels in the course of myself owning that CAI
. They were all fixed by cleaning the MAFS and resetting the ECU. The CAI
install, by a bunch of bananna eating primates, was great. The MAFS got some gunk on it during a period of time due to the K&N or any high flow filter make or design that one day threw the CEL. I switched filters because I was too lazy to clean mine and wait at the time so I purchased a dry filter with an open end funnel type (the only one I could get). I recently threw a CEL with that and cleaned the MAFS, reset the ECU, and all gone. I also passed NJ emissions with the new filter, so don't believe that getting a new filter will make you lose the carb exempt and fail for emissions according to Injen
. I also never had or have any hesitation or bogging ever due to my CAI
with the K&N or the "other" filter installed.
