Bosch Spark Plug P/N:7905

Keep the spark strong across a huge span of classic and modern engines with the Bosch Nickel Copper-Core Spark Plug (P/N 7905). This conventional nickel-copper plug is engineered to meet or exceed Original Equipment specifications and is a direct-fit replacement across 141 listed applications — from the 1971-1974 BMW 2002 [L4-2.0L] and 1974-1979 JAGUAR XJ6 [L6-4.2L] to the 1994-1997 FORD ASPIRE [L4-1.3L] and 1996-2002 LAND ROVER RANGE ROVER [V8-4.6L]. See the Buyer's Guide tab for the full list.

• Yttrium-enhanced center electrode: a nickel center electrode over a copper core, rated by Bosch for up to 50% longer performance life vs. standard copper plugs.
• Broader heat range: the copper core helps resist pre-ignition and fouling.
• Nickel-plated rolled threads: strong corrosion resistance, and no anti-seize required — saving install time.
• Anti-flash-over insulator & built-in resistor: the angled, ribbed ceramic insulator is designed to help prevent misfire from flash-over, while the metal-glass fused 6,000-ohm resistor helps suppress interference.

Specs: manufacturer heat range 8, projected ceramic insulator, flat seat, 19 mm reach, 20.8 mm hex, a single J-gap nickel ground electrode, non-removable nut terminal, and a pre-set .8 mm gap — confirm the correct gap for your engine before installing. This 4-cycle plug is sold individually (package quantity 1); the quantity needed varies by application (4, 6, 8, or 12 plugs). Country of origin: China. Manufacturer part number 7905.
