This came off a Seat LCR. sizes are length 680mm, depth 90mm, height 160mm, 2.5 pipe work with 2.1/4 ID outlets. Very good order with no fin damage. Comes with mounting brackets and pipe work, very nice intercooler, not a cheap ebay item. I'm pretty sure this will fit the S3 with a bit of tweaking, it was going on my S3 but I'm selling up now. http://www.txautosport.co.uk/seat-leon-cupra-r-lower-front-mount-intercooler-kit-342-p.asp Â£90 Paypal as gift or add fee's.
