Brisk Iridium Performance P40 RR15BYIR Spark Plug

P40 RR15BYIR Iridium Yttrium Brisk Performance Spark Plugs  Brisk SKU  -  P40 RR15BYIR Parameters: Thread Diameter 14mm Thread Reach 25mm-1" Hexagon 16mm-5/8" Seat Type Tapered Design Iridum/Yttirum  Resistor Yes Projected Yes Heat Range  -  15 Brisk P40 RR15BYIR 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 short
