BRISK Silver Racing DR15YS Spark Plug 14mm thread, 3/4"(19mm) reach, 5/8'(16mm) hex, gasket seat, projected tip, resistor, fine wire 1.5mm Silver center el., tapered ground electrode.

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. Brisk Silver Racing Spark Plugs are available for all makes and models, so order yours today! 

BRISK SILVER RACING SPARK PLUGS – Technical information Materials: Silver is the best thermal (heat) conductor of all metals - Allows for a wide spark plug heat range - Excellent heat dissipation under max. power - Excellent resistance to fouling under light load operation Silver is the best electrical conductor of all metals - Most free electrons - Best power delivery - Most powerfull spark Construction: 1.5 mm Silver Fine Wire Center Electrode - Low ignition voltage requirements (easier for spark to jump over) - Reduces stress and wear on your coil and other ignition components - Fires properly even if partially fouled, where standard plugs will fail - Excellent for: o Standard and High compression engines o Forced induction applications o Nitrous applications o Methanol/ethanol injection o LPG o Any hard to ignite type of fuel applications o High RPM race engines where is a short time for the ignition coil saturation o Beneficial even for old vehicles with a weak ignition systems and/or excessive oil consumption Tapered or Cut-Back Ground Electrode - Provides sharp edges for easy spark discharge - Excellent spark exposure to the air/fuel mixture - Faster flame front propagation in the initial stages of ignition due to reduced ground electrode obstruction High dielectric strength - Fine wire center electrode (not just tip) increases the thickness of insulator between the center electrode and the spark plug shell for higher mechanical and dielectric strength.

Nice golf pullover
Size: XX-Large, Color: Colony Blue Melange
Nice pullover 1/4 zip. Quality is pretty decent, the color and fit is really good. Leaves good flex room in the shoulders. The material isn’t to heavy and can be worn with a vest if needed. The only thing about the fit is the sleeve length. I wear in a dress shirt 35”-36” length and this hangs past my thumb.

Great 1/4 Zip for money
Size: 4X-Large, Color: Black Melange
This quarter zip pullover is a great addition to any wardrobe. The fabric is lightweight, breathable, and does a nice job wicking away moisture, making it perfect for golf or any outdoor activity. The fit is true to size with a clean, athletic look—not too tight and not too loose. The material feels smooth. The zipper is sturdy, and the overall quality is impressive for the price. It also holds up well after washing without losing shape. Nice material, wrinkle resistant and soft. Great for the course, workouts, or even casual wear. Highly recommend!

True to size and great quality
Size: X-Large, Color: Colony Blue Melange
This shirt fits true to size. It is very soft and comfortable. The fabric is a thinner fabric that can be worn over dress shirts. The quality of the shirt seems to be very good. I have bought these pullovers in multiple colors, and they all seem to be consistent with the quality and size.

Received the wrong size
Size: X-Large, Color: Navy Melange
Seemed and looked like a decent quality shirt. A little lighter weight than I expected. I ordered an XL, but received a Large, which did not fit. Returned it and bought a similar shirt in a different brand.
