Brisk Iridium Performance P6 GR15YIR Spark Plug

P6 GR15YIR Iridium Yttrium Brisk Performance Spark Plugs  Brisk SKU  -  P6 GR15YIR Parameters: Thread Diameter 14mm Thread Reach 18mm-.706" Hexagon 16mm-5/8" Seat Type Tapered Design Iridum/Yttirum  Resistor Yes Projected Yes Heat Range  -  15 Brisk P6 GR15YIR Replaces:   With very long lifespan, the P range Brisk spark plugs are the most modern design to fit modern highly efficient and stressed engines. The Iridium core center electrode is surrounded by Yttrium alloy made body and earth electrode that gives very low voltage requirement prolonging ignition coil lifespan.   Lower voltage requirement stands for easier cold starts, less of a chance of a misfire due to fouling as a result of oil burning, use of alternative fuels or prolonged idling.   Features Yttrium alloy earth electrode with Iridium core. Nickel / Zinc coating for corrosion protection Lower voltage requirement. cylindrical shape of insulator tip achieves fast self cleaning at low temperature shortl
