- Non-projected tip
- Silver fine wire center electrode
- Tapered ground electrode
- Special high dialectic strength insulator
- Silver is the best electric and heat conductor
- Superior ignition ability increases engine power
- Lower required supplied ignition voltage
- Good resistance to fouling and easier starts
Perfect for mildly modded 2011+ 5.0 L Mustangs. Brisk Silver Racing spark plugs offer better ignitability than conventional performance plugs, and have better performance and reliability in high boost, nitrous, or high compression applications.
Constructed from silver, Brisk Silver Racing spark plugs, are a better electrical and thermal (heat) conductor than gold, copper... and many times Iridium. The non-projected tip is good for nitrous or forced induction applications. The fine wire center electrode, gives more room for the insulator between the center electrode and spark plug shell - allowing in a durable spark plug with high dielectric strength.
Brisk Silver Racing spark plugs offer a powerful spark, improved performance, low ignition voltage requirements, excellent heat dissipation at full load, and excellent anti-fouling resistance under light load operation.
