Brisk Silver Racing ER12S is a special racing spark plug that Brisk supplies to European Rally teams such as PRODRIVE and its heat range is equivalent to NGK heat range 8. Ideal for turbo, supercharged, nitrous and methanol injection engines. 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 Plug DR12S 14mm thread, 3/4"(19mm) reach, 5/8'(16mm) hex, gasket seat, non-projected tip, RESISTOR, fine wire 1.5mm Silver center el., cut-back ground electrode BRISK Silver Racing DR12S spark plug was specially designed for heavy modified, turbo, supercharged, or nitrous-fed applications where engine control modules or engine management systems are extra sensitive to electromagnetic interference. In the "import" world this spark plug heat range is known as 8 (NGK heat range 8 which is heat range BRISK 12) Because of extraordinary properties of SILVER, this spark plug can be used as performance replacement of NGK heat range 8, 9. such as NGK BKR9EIX, BKR10EIX Denso Iridium IK27 Brisk Silver Racing 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 the 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. The Brisk Silver Racing plugs have a 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 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. In street applications, the greatest advantage is a powerfull spark, improved performance, low ignition voltage requirements, excellent heat dissipation at full load and excellent anti-fouling resistance under light load operation.

Projected Tip (YS) Plug designed for use with naturally aspirated or boosted GEN3 HEMI applications that use a crush sleeve spark plug fitment (not tapered seat).For Nitrous Applications we recommend the non-projected plugs (end in S), not this projected plug (YS).Low Required Supplied Ignition Voltage - this is acheived by utilization of optimized diameter Silver center electrode, along with tapered ground electrodes. Silver is the best thermal and electrical conductor of all metals and provides far superior electron flow for best possible spark delivery from the spark plug.This spark plug feature is beneficial in forced induction applications, or applications where the ignition system is pushed to the limit in modified power applications, and applications with hard to ignite fuels such as alcohol, LPG, Nitromethane and other.Brisk Silver Racing Spark Plug Lower Required Supplied Ignition Voltage is also beneficial for easier cold starts and operation under partially fouled spark plug condition caused by A/F management problems, oil consumption and other.Small diameter of the spark plug center electrode allows for thicker ceramic insulator walls and increased distance between the spark plug center electrode and spark plug shell walls.Increased spark plug center el. to spark plug shell distance, and spark plug special thick design insulator provides exceptional spark plug dielectric strength, and keeps the spark plug from dielectric break down, and or spark blow out in the most extreme working environments.
