so if i lose the 58mm twin bore, then i would be losing. this is the first mustang i've ever owned. and i thought it was just a gt until i got my insurance card.
GT owners pay upwards to $1000 for our intakes, so unless you're looking to profit, I personally say keep it. Hell, I'm getting blown by Kenne Bell () and I'm STILL gonna keep my intake, not sell it! I'll just put it in a box for safe keeping just to keep it lol.
Mikestang415 is right you can also find the acufab single blade TB at american muscle. Though the intake will require a little modification to allow the single blade to open. Make sure when you cut the middle piece out from the intake you have rags stuffed inside so you don't get metal flakes sucked into the intake. I used a grinder to clear out the middle bar and the Acufab TB works great. I'll post some pics later to show you or you can email me for them.
