Great for performance
Iâ€™ve run these plugs in my Miataâ€™s high revving engine for multiple HPDEâ€™s and got no ignition break up or misfire like I would get from other brands on the hotter days with higher intake temperatures. I also found myself changing plugs far less often than when I was running brands such as NGK and Champion. These plugs provide a much more complete burn and when I remove the plugs the color is consistently the same. I highly recommend these for daily drivers as well as performance applications. These are the best plugs Iâ€™ve come across.

I ran these plugs in my '93 MX5 and had great results. The car ran better and felt healthier than it did with the NGK's it had in it when I bought it. I've also ran these plugs for my '94 Integra with similarly positive results.
Definitely made me a fan of the E3 brand!
