  1. Allows you to do a clean electronic turbo boost guage install 5 Star Review

    Posted by on Mar 17th 2018

    I replaced my mechanical boost gauge with an isspro electronic guage so I could get rid of the plastic tee that was in line. This fit perfect and looks good too. Very happy with the results.

  2. Quality is great. Looks awesome 5 Star Review

  3. Very Nice Product! 5 Star Review

    Very nice plug with tapped port for future use of a boost gauge or monitor. This is much better than trying to perform a modification by cutting the element off the air heater itself and also better than installing an oil drain plug.

  4. Great design, high quality. 5 Star Review

    Couldn’t have a better design, and machined to perfection. That’s the riffraff way, some of the best equipment on the market in my opinion.

  7. No Brainer 5 Star Review

    Why wouldn't you remove restrictions from your intake if it is this inexpensive? Especially if you have upgraded your turbo and/or have a water/methanol setup!!! Just a bonus to get an extra tapped port for accessories.
