i was thinking of getting that BBK combo TB and plenum... any good news from it?

 

It all depends on your mods that are already on the car. The 78mm TB/elbow is a little on the large side for a stock 4.6L. From everything I've read, the 70mm TB is the sweet spot when combined with a decent upper elbow. I decided on the 75mm TB + TF elbow but that was also to feed a 5.4L with Cams.

 

well as of now i have a complete exhaust set up including headers, h pipe, cats, and cat back. i want steedas CAI but i cant figure out which TB and Plenum i want. i realized the 78mm was pretty big. im not sure at this point if ill do and FI work...
