Not hard at all. From start of taking old one off to finish was about an hour. The hardest part for me was the TPS bolts. I shot them with BP Blaster. The rest was easy. If you can change a set a brake pads, then you can do this. Same concept. Take off old, put on new.

 

Agreed. Tps was the most difficult. I just bought a new one because I stripped out the screw. It sucked. Lol

 

I have same throttle body/plenum. Very easy to install.
