Perfect fit
Very easy installation, only took 15 min. Can't tell much on performance but I'm sure it's there.

This is an high quality, direct replacement. I had no issues installing it. I'm not using the tapped hole, but it's nice to have when/if I need it. I would recommend.

Love the blue, and I plan on adding a boost gauge so the inner plug is a bonus.

This little plug is quality. My only complaint is the little o-ring that is supplied isn't very tough, and seems to bulge out after installation.

Perfect location for boost sensor
Nice addition to the truck. I did purchase the code eliminator, but I'm still seeing the soft code. No big deal though. I ended up ordering a gauge set through Riffraff that included the AIH plug for the boost sensor. So now I have 2!
Tip: be careful to keep control of the o-ring. When I tried to get the plug in, I dropped the o-ring into the valley. Took a little bit to retrieve.
Overall, awesome quality. Riffraff rocks! -
