I got mine for $220 with a mild steel flange and a 9lb spring. I traded the 9lb for an 11lb since I'm going to be running the APS BOV with the Tial. My friend got his at Automotive Engineering for $200 with an aluminum flange.
You're going to need the 9lb spring cuz the 7lb will open at idle and since you have a MAF that wont work.
