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.

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.

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

      2006 F150. I needed to replace 2 and 4. It was great for getting at 4, and got it out (there is not much room there and the flexible joint helped a lot). Moved to 2 and it snapped at the joint before breaking the plug free. Since I was able to use a deep 9/16 socket to get at that one, I'm at least fortunate to have gotten 4 out first.

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

        I bought this to change the spark plugs in a Nissan 2.5.

        The plug would not seat far enough to engage the hex part of the plug because the opening for the terminal lug is to small.
