Brisk just developed a new spark plug for this platform that is one heat range colder. It features a silver center electrode, a new terminal cup design to reduce flash over in forced induction applications and a gap-able single ground electrode. The terminal cup operates exactly the same as the traditional terminal nut and the top portion of the plug where to coil connects is the same overall length. The cup allows for the insulator body to be lengthened which increases the dielectric strength of the insulator and makes it less likely to occur flash over / spark blow out on forced induction applications.
Stock plugs at factory boost level are typically good for 50,000 to 60,000 miles. Higher boost levels on race plugs require more frequent replacement. Most street driven cars with Brisk plugs should expect to replace the plugs every 10,000 to 20,000 miles. You’ll know when it’s time, because you’ll start experiencing misfires under boost.
Brisk Silver Racing spark plugs have 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, which is the most important spark plug parameter in forced induction applications.
When you replace the spark plugs, always apply anti-seize to the spark plug threads and dielectric grease on the inside of the spark plug boots. This will ensure the plugs can be easily removed in the future and displace the air inside the rubber boots, which will in turn prevent carbon tracking and misfires under boost. We include four gram packets of dielectric connector grease and anti-seize lubricant with all spark plug shipments. Recommended torque value when installing in aluminum cylinder heads is 8 to 14 foot-pounds.
- OEM LGY spark plugs are AC Delco 41-131, part number 12650283, gapped between .026 and .030″.
- XER10Sare approximately one heat range colder than stock, and come pre-gapped to .028”. We recommend carefully reducing the gap down to .024” for tuned cars with increased boost.
