Has larger maf housing enabling mapper to rescale and get more from the stock ECU. filter was never used on mine as i already had a cold air kit so is as new. Housing body is in good condition on top but a few scuffs and scratches underneath (not visible when fitted though). £90 plus delivery, cheers
