Detailed Description

Champion 3407 is a Platinum Power spark plug designed for secondary ignition systems that call for a tapered-seat, resistor-style plug with a platinum tip. The electrode design helps concentrate the spark at the gap, while the Heat-Active alloy supports steady performance across a broad operating range. This makes it a practical choice for older Ford, Mercury, Lincoln, and Mazda engines that specify RS14ZPYC5 or related cross-reference applications.

This part cross-references Autolite AP5143 and AP5144 for the same application. It is listed in fitments including 2007-2008 Ford Ranger, 2006-2007 Ford Freestar, and 2001-2005 Mazda B4000, as well as additional Ford Mustang, Ford Thunderbird, Mercury Cougar, and Lincoln Continental applications. If you are searching for Champion Platinum Power 3407 for a Ford Ranger or Ford Mustang tune-up, verify the exact engine and gap specification before installation.

What It Helps Address

• Hard starting caused by worn or inconsistent spark plugs
• Rough idle from weak or unstable ignition output
• Misfire conditions tied to plug wear or incorrect gap
• Reduced throttle response from degraded secondary ignition performance
• Maintenance replacement for vehicles calling for RS14ZPYC5-style plugs

Installation Notes and Tips

Confirm the vehicle’s required plug type, seat style, thread diameter, reach, and gap before installation. This plug is listed with a 0.050 pre-gap, but several fitments note different gap requirements such as 0.044 or 0.054 inches, so always follow the engine-specific specification for the application. Use proper spark plug service procedures and torque to the manufacturer’s specification for the vehicle.

Compatible With select Ford Ranger, Ford Mustang, Ford Thunderbird, Mercury Cougar, Lincoln Continental, and Mazda B4000 applications listed in the fitment data. Part number 3407 should be matched to the exact engine code and plug specification before use.
