HKS M-Series Super Fire Racing Plugs (x4)
If you are seeking an increase in power please ask Cherry Tuning and Performance for the various options that will suit your plans and wallet. Great advice. Once you do that, fit these to keep everything running smoothly. I fitted the Race Chip RS and paired it with these plugs.
Easily installed along with a racechip RS I found these to make the car idle a lot better. Good value for $$
Plugs supplied were pre gapped and ready for fitting. I will see the full affect of these when I get my car tuned but they will still work well on a factory car.
