This or similar product is necessary to make removal of the plugs for Ford 5.4L easier. Ford made the process very complex and this tool helps.

Following Ford's guidelines I backed the plug out 1/8th turn and added a small amount of penetrating fluid to loosen carbon and other buildup before removing the plug. Ford calls for Motorcraft carb cleaner, I used Sea Foam Creep. I waited two hours instead of Ford's lesser amount of time for the cleaner to do it's job. I then backed the plug out another 1/4 turn, and then re-tightened, backed out 1/4 turn and waited another 15 mins. Then removed the plug with none of the horror stories you will find about this process.

You will need multiple extensions and swivel to get to a convenient place to turn a ratchet.

Doesn't fit the Motorcraft SP-509 used in Trition V8

Despite the fact that this socket is specifically advertised for the spark plugs used in the Triton V8, it is too shallow to accommodate the Motorcraft SP-509 plug currently used in the Triton V8. Kudos to Advance Auto for offering to refund my money despite the fact that it was outside the 90 days.

    Great look and feel. Does not fit inside the engine block area, need a thin wall 14mm socket for Infiniti's.

      Comments about Gear Wrench 9/16" x 6" Magnetic Swivel Spark Plug Socket:

      I purchased this product to help remove the spark plugs on my 2004 Ford F-150 pick up truck. The engine in this truck is a 5.4L with 24 valves. The plugs in this vehicle are notorious for breaking into two pieces, and require a special tool to remove. They sit very deep in a well on top of the heads, and are difficult to access especially the ones at the rear of the engine near the firewall. This swivel headed socket really helped to get the angle needed to remove the plugs, and the magnetic feature was priceless removing the 2 broken plugs that I encountered. I wouldn't recommend tackling this project without this valuable tool.
