  • Vehicle power must remain between 11.5 and 15.0 volts
  • Parking brake must be applied
  • The transmission must be in Park or Neutral
  • Glow plugs must be off

    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

    Posted by Jonathan Lo on Jul 5th 2019

    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!
