Brisk Spark Plugs - Racing ZS

Brisk Racing Spark Plugs - ZS

These quality plugs are for high performance engines needing the absolute most out of the combination.

I have tested these plugs and have made power gains just by changing to these spark plugs.

These are what I use in my own 800+ HP drag car.

They are a 12mm thread long reach plug only.

The price is per plug (minimum order of 4)
