“I have had issues with melting down plug boots on other wires. In fact we couldn’t even finish tuning because it melted them down on the dyno. In my search for a fix I ran across FireCore Performance which has a ton of great reviews. So I reached out to Rick Gorski and he walked me through the whole process and went over boot options for my high heat issues. He went above and beyond to help cure my issues. And this motor will twist up past 7000 once again!! I am very thankful I found this company and if anyone needs wires, I promise you these are the best wires I have ever seen!”

“Shout out to Rick Gorski I ordered these wires yesterday at 2pm and they where just delivered. So in 26 hours time they where assembled to my desired lengths and shipped to my door step. Wow that’s customer service I’m definitely not used to receiving.”

“The difference in quality and build of the ProMod wires is top notch. The click and feel during the installation into the coils on the plugs were much more certain. The extension of the plug and makes access much easier along with the boots being narrow were for more clearance. All in all extremely happy”
