2018. he has a thread posted below but they banned him already because that forum has a moderator who is on a power trip and has a severe "my way or it's deleted" attitude. i think his banning was over k&n filters ruining MAF sensors or some other odd rumor.What year/gen is your friend's Mazda 3?
check it out. i chimed in sometimes as rob342. i randomly stalked and found him there because i'm weird like that and find it fun to mess with my friends. i knew he had a new car which meant it was probably on a forum somewhere.
