i just made a appoinment with mazda dearler for CEL'S problem. currently the engine bay is stock..
08 MICA BLACK MAZDASPEED3
SYNAPSE BOV, INJEN CAI.
uh...your engine bay is not stock. stealership may turn a blind eye to a CAI, but prob not to a BOV. if i were you, i'd remove at least the latter.
Yet another reason to only use Mazda Mazdaspeed performance upgrade...
