RX Performance's Ported Throttle Body Review & Installation Tutorial(for LFX engines)

First off - I have to admit, the tutorial is going to be short and sweet. This is by far the easiest throttle body I've ever had the pleasure of working with. No vacuum lines, no coolant lines, no mechanical linkages, just ONE electrical sensor and 4 bolts.

The throttle body fresh out of the package:

1. 10 mm Socket w/ Socket Wrench
2. Flatblade Screwdriver

Step 1. Remove the engine cover.

Step 2. Unhook intake elbow from throttle body. For my Cold Air Inductions cold air intake, it was just a matter of unscrewing the clamp and moving the elbow out of the way. Your mileage may vary.

Step 3. Under the throttle body is the electrical sensor. There's a red piece of plastic which needs to be pulled out, use the screw driver to push the tab back. Once it's back all the way, you can push down on the plug where the plastic piece used to be against and then slide towards the passenger side to get it to slide out from the throttle body.

Step 4. Using the 10mm socket wrench, remove the 4 bolts around the perimeter of the throttle body. The bottom right bolt is kinda hidden, but it's in there.

Step 5. Hold new throttle body in place and reverse steps 1-4.

Install was a breeze. After installing, I drove it around the block but not that far yet... literally just finished installing it 10 minutes ago. I'm trying to be as unbiased and not give into placebo as possible. It seems like I don't have to rev as high to get the car to start moving in 1st gear. I actually squealed the tires a little bit when I pulled out of my subdivision because I'm used to giving it more gas. Taking off from a stop in 2nd gear seems to be nicer too, as it doesn't seem to lug at first like it used to. All in all, for a quick trip around the block it *seems* better, but I'm going to drive it to my parents' house to drop the car off for a week so I won't have much more feedback for a little while. All in all, I think this was worth the price!

Drove the car to my parents' house to drop it off with my dad for a week while I have a company vehicle. I used 2nd gear to take off and WOW what a difference. There was absolutely no lugging at all taking off from a complete stop. It takes off confidently and smoothly. That was the most impressive change. Very cool!
