Moving on to the fun part: is there a difference to the standard OEM plugs? Well, hell yes, there is! My baby starts up almost instantly, and she accelerates even better than before. I felt it most while accelerating in lower RPM and higher gears on the highway: you feel the cars’ pull immediately with these new plugs. People did not exaggerate, and I love it!

Now a few last words of caution from someone who did her research: when choosing your Rx8 spark plugs make sure you consider your daily driving style!

I use the NGK Laser Iridium sparks because although I love to drive my babe in high RPM, I only do it in shorter bursts and, I daily drive her around 3-4k RPM. So the medium heat range from the NGK is perfectly fine. If you choose a plug with a very high heat range (e.g. Denso Iridium Racing) and you don‘t drive accordingly in constant high RPM, your plugs will quickly foul, and you‘ll find yourself back with the issues I mentioned at the beginning.
