BRISK Silver RacingDR12YS 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 electrodeBrisk 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.

Very tight fit on 74mm Mobile 1 Filters
Color: Silver
It claims to fit "some" 74mm Mobil 1 filters. It's a fraction too small, but will work if you "force" the tool on the filter.

Works if you need help. Not a miracle in a bottle.
Size: 1 Count (Pack of 1)
It has worked every time I've used this product. Won't fix a damage catalytic converter but will help you pass the test if your car almost passed.

Worked like a charm.
Size: 1 Count (Pack of 1)
Used it as directed. Down to an eighth of a tank. Poured it in and added enough gas to get back to one half a tank. Wanted to get it mixed in really well. Immediately jumped on the interstate and ran 75 MPH for 40 miles. Stopped and filled the tank and when I restarted the engine, the light was off. Coincidence? Not a chance. Light had been on continuously for weeks. AutoZone said I needed a catalytic converter. Nope. One thing I found out the hard way. If your gas filler has a flap at the top, make sure it is easy to push aside. Mine had a little release button near the top that the filler hose would depress before the flap would release. Dumped the first bottle right on the ground. Twelve bucks wasted. No one to blame but me, I guess. Still a bargain, even at twice the price.
