Review on HKS 50003 M45XL Super Racing Spark by Jason Przystup

Revainrating 5 out of 5

To use them you need to tune your car.

racing spark plugs that require other modifications to see the full picture. If you put them in a stock engine and think it'll get better, you're right, but the candles will start to get dirty. However, it is better than a pre-ignition. They come in one package so keep that in mind. They are way better than other forks.

Pros
  • Ignition and Electrical
Cons
  • Fits
