ProCharger 101 - Spark Plug Tech for Supercharged Engines

Ever asked yourself: What spark plug is one heat range colder? What spark plugs do I use when supercharged? How do you “gap” plugs? Or why does any of this matter? Well you have come to the right place, because that’s exactly what we cover in this ProCharger 101 video.

More videos please! I love Procharger. I wish you guys would do more videos highlighting racers both- pro and amature- using your systems.

Thanks for the information. Especially the Coyote. I have a 17 Mustang gt with roush supercharger. I've been gaping at 30. Now for a fresh new set of plugs gapped at 18-22.

I've got a 2019 Mustang GT that had one of the first 50 state legal kits installed here in California. Getting the right plugs gapped right took a little trial and error but I've been running this thing ProCharged with a P1X for over 2 years now and I love it! Perfect combo P1X and Coyote 5.0

Hey my mustang did almost the same-thing equip with procharger
Wide open throttle it would pop a cat code
After some research a a ha moment the spark plug gap was set as per ford
I pulled-the plugs and recapped them to nearly haft the amount
Tested and no codes no miss
So procharger is letting in a boat load of air
Well guess what air gap is a pretty good insulator
Yes more air with more fuel bigger boom but to start the boom you need the spark the ability to under high boost means plug needs to over come the distance
You need a higher energy spark or move the gap closer
Worked in my case to tighten the gap
Hope this helps

Thanks for the great videos, much appreciated. Do you recommend a .028-.032 Gap for a Cherokee SRT 6.4L D1SC System running @8 lbs of Boost? (I’ve read somewhere else .035 Gap)
Thanks Much

The instructions for my kit said .035….? What the what? I still gapped to .028 though. I running 10-11psi and water/methanol.

Installed a procharger on my dodge a few months ago. Is vp unleaded octane booster bad for my plugs? Heard stories they mess up the tips with use.

Great video. Is a projected tip more likely to detonate than a standard on a small block Chevy around 850 HP?

Supa dupa helpful. Thank you for making this.

Should not be telling people to shut off ignition at that stripe it's a good way for some transmissions to explode like a bomb went off!
