Check out my album and let me know what you think. My stock airbox was total junk. It would not seal above the filters and I kept getting fine dirt in my intake. I also did the CCV mod at the same time. The only good thing about the stock CCV setup is that the oil was trapping some of the dirt that made it past the airbox. Luckily, my turbo looks o.k. Before I had the box made and installed the hood scoop, the filter was just in the engine compartment. Before and after driving has shown much cooler EGT's with the cold air, as expected. Without an intercooler, we need all the help we can get. Total materials was around $150. WRX type hood scoops are all over ebay, this one was $28 shipped. I plan on cleaning up the airsensor and "bungie" mounting, but this works for now.
