Agent 47 makes the double barrel strut tower bar that will fit the plenum cover or supercharger. A47 Double Barrel
i am pretty sure Strange Development has one that will clear, no problems. they are made from aluminum, and the entire shipping weight was something like 3lbs! i have had mine for a few years now and is holding up well!! https://www.strangedevelopment.com/StoreCC/index.php?act=viewProd&productId=5
I tried the Ford Racing brace that came with the FRPP kit but it didn't look like it was going to fit.
I, too, had the FRPP brace, and it did not fit over the plenum cover. I took the cover off but it always irked me that I paid extra for something that I couldn't enjoy. I bought the Bullitt one (pictured above) and it fits great, about 3/4" of clearance. It is the same as the FRPP V6 brace, only powdercoated silver, as far as I can tell.
