Description

We recommend heat range 7 for SR's putting down 300-450hp.
If you are at 450hp, and doing long sustained wide open throttle events such as road racing, we recommend stepping up to heat range 8 for SR's.
For KA's, heat range 7 will work well up to 500.

Very good plugs for moderately modified SR20DET engines. This is one step colder then stock heat range.
These will perform very well on well modifiied KA24DE-T engines (2 steps colder).  Great for road course with long straight-aways.
