Spark Plug - BKR4E Features & Benefits: V-Power Spark Plugs are named for their specially designed v-groove centre electrode to improve ignitability. Tested to the highest original equipment standards, these plugs are crucial for vehicle maintenance. Cold-rolled threads prevent cross-threading and damage to cylinder heads Trivalent Metal Plating has superior anti-corrosion and anti-seizing properties (eliminates need for anti-seize) High-grade alumina silicate ceramic creates a stronger insulator to reduce dielectric punch-through (caused by spark exiting through side of ceramic) 98% pure copper core increases heat dissipation for reliable starts and prevents spark plug overheating 90 degree V-Groove centre electrode allows the spark to occur closer to the outside of both the centre and ground electrodes for better flame expansion, reducing quenching and improving ignitability Common Applications Include: BENTLEY BROOKLANDS 1994-1995 BENTLEY CONTINENTAL 1994-1995 BENTLEY TURBO R 1994-1998 ROLLS-ROYCE CORNICHE 2001 ROLLS-ROYCE CORNICHE IV 1994-1995 ROLLS-ROYCE CORNICHE S 1995 ROLLS-ROYCE FLYING SPUR 1995 ROLLS-ROYCE SILVER DAWN 1995 ROLLS-ROYCE SILVER SPIRIT 1994-1995 ROLLS-ROYCE SILVER SPUR 1994-1998 ROLLS-ROYCE TOURING LIMOUSINE 1994 Product Specifications: Centre Electrode Core Material Copper Centre Electrode Tip Material Nickel Electrical Terminal Type Non-Removable Nut Gap Size (IN) .036 Ground Configuration Standard Ground Electrode Core Material Nickel Ground Electrode Quantity 1 Ground Electrode Tip Design Standard Hex Size (IN) 5/8 Insulator Height (mm) 50.50 Manufacturer Heat Range 4 Part Number BKR4E Reach (IN) .75 Resistance (ohms) 5000 Seat Type Flat Stock Number 4421 Thread Diameter (MM) 14.00
