SPARK PLUG FORD LATE V8

Description

Bring a stronger spark to every cylinder with the ACCEL HP Copper Spark Plug (MPN 8161C1) — a copper-core resistor plug that installs as a direct-fit replacement for the 2008-2014 Ford Expedition (V8-5.4L), 2008-2010 Ford F-150 (V8-5.4L), 2008-2010 Ford F-250 Super Duty (V8-5.4L), 2008-2010 Ford F-350 Super Duty (V8-5.4L), 2008-2010 Ford Explorer (V8-4.6L), 2008-2010 Ford Explorer Sport Trac (V8-4.6L), and the 2008-2010 Ford Mustang (V8-4.6L). It's packaged as a set of 8 to serve a V8.

Copper core: the manufacturer rates it a better conductor than platinum or iridium, designed to deliver a stronger spark in high-performance, high-combustion-pressure use.
Runs cooler: copper dissipates heat well, which the manufacturer notes helps reduce the chance of misfire — and it's one heat range step colder than stock.
Gapable: unlike many iridium or platinum plugs, the gap can be opened for a larger flame kernel or closed for high-boost setups.
Machine-rolled threads & C-Cut design: intended for precise thread engagement and torque retention, with the C-Cut un-shrouding the spark kernel for a better burn.

Specs: tapered seat type, 12mm thread size with 1.25mm thread pitch, 1.040 in reach, 9/16 in (0.5625 in) hex, projected tip, and resistor construction. Recommended torque is 7-11 ft-lbs. Country of origin: Czech Republic.

Direct-fit for the 2008-2014 Ford Expedition, 2008-2010 F-150/F-250/F-350 Super Duty (V8-5.4L), and 2008-2010 Explorer, Explorer Sport Trac and Mustang (V8-4.6L). See the Buyer's Guide tab.

How many spark plugs come in the package?

It's packaged as a set of 8, enough to plug one V8 engine.

Is this a resistor spark plug?

Yes, it's a resistor-type plug, which helps suppress radio-frequency interference generated by the ignition system.

Can I adjust the gap on these plugs?

Yes — ACCEL HP copper plugs are gapable, so the gap can be opened for a larger flame kernel or closed for high-boost applications. Set it to your engine's spec.

What are the plug's key specs?

Tapered seat, 12mm thread with 1.25mm pitch, 1.040 in reach, 9/16 in hex, projected tip, and one heat range step colder than stock; recommended torque is 7-11 ft-lbs.
