Ok i have been reading lots of posts of people confused at what to do with with their airbox on their mk4 1.8t
I didn't wanna put a cone filter on for 2 reason, Mpg suffers and so does performance as the engine is sucking in very hot air from around the engine bay area.. I know R-tech and other companies make a small housing for theirs which I could buy, but after speaking to them they told me they have got better numbers on the dyno with a standard airbox.. My problem was i upgraded my Tip to a Creation Motorsport oversize TIP with a 80mm maf end. I ended up bolting a mk1 Audi Tt 225 airbox in, it fit perfectly. BEWARE THERE ARE DIFFERENT AIR BOXES.. Some don't have the return breather pipe hole but I managed to find one on Ebay for £28 fits perfectly.
Roll on next month as I start making my custom intercooler pipes 3"
