ive had my airtec on for ages now and its great it reduced the temps, it fitted ok, it was a little heavy though but who cares! your paying 100quid for a brand new reconditioned standard one of ebay that goes pop like mine did within three months or your hunting around all the spares place for a decent old one, my mates on his 4th now and theyve all leaked at 80quid a pop!
