This plug was extremely easy to install and I am by no means a mechanic! I installed it in my 2000 Ford Excursion 7.3 Diesel in about 10 minutes. It really is as simple as removing the intake heater, disconnecting a couple wires and screwing the plug in. That's it! It also looks great (I ordered the blue one and I love it!). This was my first experience with Riff Raff Diesel and will definitely not be my last. Clay answered my emails within minutes even late at night because as a first time diesel owner I had a few questions. This is the best company I have dealt with by far for diesel products and they will now be the ONLY one I call. Please give them a chance to earn your business, you will never regret it!!!!!

This plug threaded in perfectly and was exactly what I needed. The appropriate spot for a boost gauge indeed.

Best part is no additional drilling and tapping required. Fits snug so no leaks.

Now no more check engine light and fuel cut off when I boost over 22psi. Nice clean install.

Don't over tighten it, it strips easy. Otherwise great.

In stalled in NP time and hooked boost guage up and work 100%. Thanks riffraff

Pretty straight forward item... perfect fit and a nice place to tap in for a boost gauge.

looks and worked great for eliminating unwanted air heater & installing glowshift boost pressure gauge.

I got this plug to do an air intake heater delete on my 03 duramax and it fit and worked perfectly also used it to run my boost guage for a simple no drill application that looks almost factory. Great product.
