Product Details

Part number 94806 uses NGK’s Laser Platinum construction to support dependable ignition performance in everyday driving and higher-demand service. The platinum center electrode tip helps maintain consistent firing characteristics, while the copper core and nickel ground electrode materials support efficient heat transfer and stable operation. This spark plug is specified across many OE-equivalent Ford and Lincoln applications, including 2011-2017 Ford F-150, 2011-2018 Ford Edge, 2013-2019 Ford Flex, 2013-2016 Ford Taurus, 2013-2016 Lincoln MKZ, and 2006-2015 Mazda MX-5 Miata. This part cross-references Ford and Motorcraft-style applications such as AT4E-12405-AA and CYFS12F5 for the same application.

Common Issues This Part Can Address

• Rough idle caused by worn or fouled spark plugs
• Hard starting from weak or inconsistent spark output
• Misfire codes related to degraded plug electrodes
• Reduced throttle response from inefficient combustion
• Service interval replacement on OE-recommended maintenance schedules

Installation Notes

Verify the listed fitment before installation, especially on Ford F-150, Explorer, Transit-150, Transit-250, Transit-350, and Lincoln Continental applications. Confirm the 0.052 in. gap specification where noted, and inspect coil boots, plug wells, and threads before installing the new spark plug. Use the correct torque procedure for the tapered-seat design and follow the vehicle manufacturer’s service information for the exact engine configuration.
