TL;DR Motorcraft is Ford's OEM parts brand; the SP-548 is the factory-recommended double-platinum replacement for the 5.0L Coyote V8, superseding the original iridium SP-519. Both electrodes are platinum-tipped, rated for Ford's 60,000-mile service interval, and community owners report no fitment or construction issues.
The SP-548 (CYFS-12-F1) is Motorcraft's double-platinum plug for the 5.0L Coyote V8 in the 2011-2020 F-150 and 2011-2017 Mustang GT. Both center and ground electrodes are platinum-tipped, matching the Coyote's 60,000-mile OEM change interval. The plug ships pre-gapped to Ford's 0.049-0.053 in specification; owners recommend verifying before installation. The 8-pack covers all eight Coyote cylinders. Consistent reports of smooth idle restoration after replacement; no insulator failures, thread galling, or electrode detachment reports found in the reviewed sample.
Right pick for any 5.0L Coyote V8 owner (2011-2014 F-150 12th gen, 2011-2017 Mustang GT) at the 60,000-mile OEM platinum interval. Skip if your F-150 has the 3.7L Ti-VCT V6 or 3.5L EcoBoost (different Motorcraft part numbers apply), or if your Mustang has a supercharged configuration requiring application-specific plugs.
No chemical exposure pathway: the SP-548 is a passive ignition-system replacement part with no SDS. The double-platinum electrode tips carry a small precious-metal mass per plug, partially offset by the 60,000-mile service interval. The steel shell is recyclable as ferrous scrap; the alumina-ceramic insulator goes to landfill via standard municipal disposal.
Yes. Ford issued a supersession replacing the original iridium SP-519 with the platinum SP-548 for the aftermarket service interval. Both plugs are correct for the 5.0L Coyote; the SP-548 is the current recommended OEM replacement.
Yes, based on community reports from owners who have installed these plugs. Both the center and ground electrodes are platinum-tipped, which is consistent with the 60,000-mile service interval Ford specifies for the 5.0L Coyote.
The plugs ship pre-gapped from Motorcraft. Ford's specification for the 5.0L Coyote is 0.049-0.053 in. Experienced owners recommend verifying the gap before installation rather than assuming factory pre-set is within spec for every unit.
Yes. The SP-548 is listed by Ford for the 5.0L Coyote V8 in both the F-150 (2011-2020) and the Mustang (2011-2017), as well as the 5.2L Voodoo Mustang (2015-2017, without supercharger).
The 5.0L Coyote V8 has 8 cylinders and requires 8 spark plugs. This listing is sold as an 8-pack, which covers a complete engine set.
