Good for Expedition Triton 5.4 3V
Pricey, but cheaper than local parts store or dealership. Delivered in single-plug Motorcraft boxes (not 4 pack like dealership) and stuffed into an Amazon padded mailer. Boxes were crushed, so inspected plugs, ceramics and gaps looked ok. After warming up engine, removed COPS, connectors and some lines to access plugs and turned each <1/8 turn. Sprayed each hole with Kroil (few squirts, just covering hex head) and let them soak overnight. Next day removed old plugs (looked like SP515’s) with lots of creaking and elbow grease, but no broken plugs! Cleaned each hole with vacuum, carb cleaner, rags, compressed air, etc. and used a borescope to inspect plug holes. Followed Ford TSB guidelines and YT Tech recommendations (nickel AS on lower portion, AS dots on upper part of threads). Torqued, reassembled and fired right up. 500 miles so far, all good.

The packaging was less than expected. Plugs were not in the box of 4, just loose in the shipping bag. I know the product so that's good don't look damaged atm.
