It looks like most others, very much like the MMR one MMR is claiming not needing a tune, it DOES! I have no clue but I think about 1 in 5 on here with the MMR filter alone have gotten by with no tune and no CEL... :shrugOUPony said:
The only CAI I for sure know not needing a tune is K&Ns!
I'd get a tuner and a tune BEFORE I went shopping for CAIs but that's just me... same power, better, cheaper running car... then you add the CAI for 10 or so more... :thumbup
