The new Mustang GT 5.0 V8 engine makes plenty of power from the factory. If you’re looking to modify it though, you might need new spark plugs. Brisk silver spark plugs use silver instead of gold or copper for better ignitability. There are the same spark plugs used in the fastest 2011 Mustang GT. They can be had in the stock heat range or up to three steps colder for forced induction engines.

Official Release

Brisk Spark plugs for the new 2011 FORD 5.0L, V8 engine are:

Stock Heat range:

ROR15LGS, RR15YC-1

One step colder:

ROR14LGS (N/A app. only), RR14YS (projected tip- low boost forced induction app.), RR14S (non-projected tip-good for nitrous or forced induction)

Two step colder:

RR12S (non-projected tip) – High Compression, Forced Induction and/or Nitrous

Three step colder:

RR10S (non-projected tip) – High Compression, Forced Induction and/or Nitrous

Brisk Silver Racing spark plugs have a better ignitability than conventional performance spark plugs, and offer better performance and reliability in high boost, nitrous or high compression applications. Silver is an element with most free electrons, and is the best electrical and thermal (heat) conductor of all metals! Better than gold, copper …and many times better than Iridium. Brisk Silver Racing RR12S spark plug has 1.5mm optimized diameter fine wire center electrode (not just the tip), which gives more room for insulator between the center electrode and spark plug shell. More insulation results in a durable spark plug with high dielectric strength – the most important spark plug parameter in forced induction applications. Brisk Silver Racing spark plugs power 2 of the World’s fastest 2011 Mustangs owned/built by: Richard Lelsz/Strictly Performance ([email protected]) as well as Justin Burcham/JPC Racing, and played a key role in setting the new World Record!

Brisk Silver Racing Spark Plugs provide powerful spark, improved performance, low ignition voltage requirements, excellent heat dissipation at full load and excellent anti-fouling resistance under light load operation. Brisk Silver Racing Spark Plugs are available for all makes and models, from stock application to over 3,500 HP applications, so order yours today!
