Thanks! I hope this will fit! I have been reading a lot of post about fitments and still unsure if it will fit. Just got to wait for today to arrive!

So I installed today when it arrived. First, the weather in Chicago is raining and snowing... It was my first time opening the engine like this. Everything went well until my friend and I forgot to take off two screw and we had to do everything again. When we finally took the two screws off, we began reassembly. However, I do not have the "star" screw to take the TB off and could not install the copper. I did went for a small drive to test it the new mod. The pedal felt more responsive. This is not to mention I have the stillen CAI along with catback exhaust. I guess tomorrow I have to figure out a way to install the copper.

Would the screws for the throttle body by hex screws? The screws Motordyne gave me looks to be hex. Maybe it was so dark I didn't notice.

I just did 5/16 plenum spacer, ISO thermal, copper TB over the weekend. TB is held on with 4 Hex bolts Allen key. It's much easier to remove using ratchet style IMO. I had an issue with installing copper TB, as one of the copper tubes would not allow proper fitment. One option was to cut the coolant tube from the upper plenum, but that would be permanent, so I use a screwdriver and stuck it in coolant tube and used a little force to slightly bend it out of the way, it worked like a charm>
