The BPMR7A 4626 is a compact type spark plug by NGK, M14 x 1.25, with one ground electrode, thread length 9.5 mm and hex size 19 mm.
It has one nickel center electrode, a resistor and gasket type seat.
NGK Compact spark plugs are approved and recommended by OE for reliable performance for most automotive and non-automotive applications.
They feature a 5-Rib insulator design to prevent flashover and are also treated with corrosion-resistant plating to ensure ease of installation and removal.
Stock Heat Range is a "7".
( "6" is used in busses and Type 3s. "7"s are a really "Hot Street" plug, and "8"s and "9"s are almost exclusively Turbo Use.)
Features:
• OEM quality
• Triple gasket sealing process
• Consistent performance
• The spark plug of choice in millions of applications
• Cold rolled threads prevent damage to cylinder head.
• NGK's triple gasket sealing process virtually eliminates gas leakage past the shell.
• Solid Copper Core provides superior heat dissipation, conductivity and a broader heat range.
• Trivalent Plating - three step plating process utilizing silver chromate and zinc ensures maximum corrosion resistance.
• With resistor of 10k Ohm approximate value.
