For Sale: HKS nonadjustable "newer version" blowoff valve for $150.It sounds like a eagle under a hood i guess u can put it.Also it DOES have a rubbing or minor scratch on the top from rubbing under the hood but thats normal and does NOT effect the way it works. Also i do not have the original plug or original insert but i do have one that fits the hole i bought a plug at Home Depot and also have a upgraded "purple" insert bought at RacingZone for it and you can get different inserts and they make the sound different. I am willing to meet in tampa, oldsmar, tarpon springs. Everything works GREAT and NO problems at all. just lookin for something different i guess.
