Brisk GRS Silver Racing Spark plug is designed for forced induction applications and nitrous applications. Brisk GRS Silver Racing Spark Plug replaces NGK heat range 6 and 7. Most popular applications are modified Ford Lightining and Harley trucks, Ford Mustang Cobra & GTO.

Brisk Silver Racing Spark Plugs have a smaller diameter silver core and conventional open spark hook type earth electrode give an outstanding performance in igniting high octane fuel mixture associated with alternative fuels like CNG, LPG, Propane, E85 blend, Alcohol, LNG, Race Fuels and Nitro. 

Silver metal is the single best material for a spark plugs core electrode, as it can dissipate heat fast, resulting in overall lower spark plug temperature and a more powerful spark.

The stronger the spark the faster and better the flame front and flame speed giving smother higher RPM range in engines. 

Our Silver Racing range works well with most aftermarket and OEM ignition systems form simple coil and distributor through electronic ignition and powerful direct ignition systems found on modern port and direct injection performance engines.

Features

• Fires properly even if fouling occurs, common standard plugs failure.

• Silver centre electrode, best thermal (heat) & electrical conductor.

• Lower voltage requirement.

• Reduces wear on coil, leads and other ignition parts.

• 1.5 mm Silver Wire Centre Electrode

Applications

• Tuned and race engines.

• Alternative fuel cars.

• Old vehicles with weaker ignition systems and/or excessive oil consumption.

• High RPM race engines with short time for ignition coil saturation.

• High octane or hard ignition fuels.

• Methanol, ethanol, CNG, LPG, Propane, E85 blend, Alcohol, LNG, Race Fuels, Nitro, Nitrous.

• Naturally aspirated or forced induction applications

• Standard and high compression engines

Service Life

• 30 000 km or 18 000 miles.

• 50 hours racing.

Brisk Silver Racing spark plugs have helped Tim Lynch and Steve Petty to keep the A/F mixture lit and set 4 New World Records since they started using them in their extreme 3,000+Hp 6.66sec @ 223.5mph Twin Turbo 10.5 Outlaw Mustang, and can do the same for you.
