Bosch Spark Plug P/N:6721
Fire every cylinder cleanly with the Bosch OE Fine Wire Single Platinum Spark Plug 6712 — a direct-fit Ford F-150 spark plug that also drops into hundreds of other listed classic Ford, Buick, Chevrolet, Cadillac and GMC engines. The fine wire design places a platinum firing pin on the center electrode and pairs it with a tapered ground electrode for an economical upgrade over conventional copper-core plugs. Bosch engineers this line to meet or exceed Original Equipment specifications for platinum spark plugs.
Sold as a single plug (package quantity 1, sold in a minimum order of 4); quantity varies by engine, so order the count your application requires — many of the listed V8 engines take 8. Fits a wide range of classic and vintage applications — see the Buyer's Guide tab for the full list.
Does this Bosch spark plug fit a Ford F-150?
Yes. The 6712 is listed for many Ford F-150 applications, including 1975-1987 and 1990-1996 V8-5.0L, 5.8L, 6.6L and 7.5L trucks. Check the Buyer's Guide tab to confirm your exact year and engine.
Do I need to gap these plugs before installing?
No. The 6712 is pre-gapped at 1.1 mm and has nickel-plated threads, so it installs quickly without adjusting the gap or applying anti-seize.
How many spark plugs do I need?
This listing is for one plug, sold in a minimum order of 4. Quantity varies by engine — many of the listed V8 applications use 8. Order the count your engine requires.
What makes the fine wire platinum design different from copper plugs?
The fine wire design uses a platinum firing pin on the center electrode, which requires up to 24% less voltage to ignite and lasts up to 2 times longer than standard copper spark plugs.
Is this a resistor spark plug?
Yes, the 6712 is a resistor-type plug. It has a tapered seat, 16 mm hex, 11.2 mm reach, J-Gap configuration and a ceramic insulator, and is made in Germany.
