Brisk Racing Spark Plugs HO14LGS Spark Plug, Premium Racing, 14 mm Thread, 12.7 mm Reach, Heat Range 14, Tapered Seat, Non-Resistor, Each

Brisk Premium Racing Spark Plugs LGS have unique multi ground electrode design and a silver core giving an outstanding performance in igniting over reach mixture associated with tuned performance engines. As the arcing occurs around the 360 degrees and is not mixture dependent a bigger gap is used at lower voltage levels thus increasing greatly an ignition surface area. 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 more powerful spark. The stronger the spark the faster and better the flame front, couple this to the multi earth electrode design and the dependents on a homogeneous mixture needed to be found around specific point, as it is the case on single earth, hook electrode. is not required. LGS 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 Discharge at richest mixture point around 360 degree perimeter. Patented firing tip design, no indexing or gaping required. Silver center electrode, best thermal (heat) & electrical conductor. Lower voltage requirement. Applications Tuned cars. Unleaded fuel cars. Racing engines. Alternative fuel cars. Service Life 60 000 km or 40 000 miles. 50 hours racing.
