Q: I have a 2014 f150 5.0 will my KN Intake work on this throttle body or does it require a larger intake boot to fit over?
A: Yes, you can use your stock intake or intakes designed for the stock throttle body.
Q: Hi, I have a 2012 F150 5.0. Why would I choose the BBK 85mm vs the 90mm throttle body when they both advertise the same horsepower increase? I currently have a CAI, Gibson Sport Exhaust, and your custom, tuning. I plan on doing a full headers back exhaust soon if that makes any difference whether or not I should go with the 85mm or if the 90mm is worth it for me. Thanks
A: If your current throttle body is causing restriction, then upgrade to one of these. Should it be working correctly, there is no need to.
As for which would be better for your vehicle between the 85mm and 90mm, that question should be posed to the manufacturer. From a tuning aspect, neither makes a difference in how we calibrate the tunes.
