selling my big Perrin "big maf" intake for half of the price of a new one. Came off my 06 wrx and I no longer need it, but willing to work out the price. I need the money for my tuition. These are mainly used for big turbos like the "Garret gt30r", but I used this one on my stock td04, and was tuned.I'll be wiling to work something about the price, since it is a little cheaper than a newer one.
