They Work!

Work as described. Much better design than the SP 515 and other versions before that.

Heads up, if you are replacing originals, you'll want to use an impact wrench to prevent breakage. The original spark plugs are two-piece, and due to carbon buildup on the firing tip, are prone to getting seized in the engine head. The impact wrench shocks the plug and keeps it in one piece at removal. I did all eight of mine with no problem whatsoever. You'll also want to order a universal joint to access the Cylinder 4 plug. Socket size is 9/16".Read full review...

Awful Spark Plugs

I purchased a set of 8 spark plugs. Only 2 of them worked and the rest were garbage. I waited 1 month for a horrible product. I will never purchase these again.

Great value 4 known products

Can't tell these plugs from OEM, either in the performance or the specifications. Did the 100k plugs & coil pacs on my Ford truck. Runs great, passed all diagnostics testing. Beats all parts store prices by a ton.Read full review...

Only way to go!

Original plugs took a crap out of the box (SP515) found out Ford replaced them with the new version (SP546) and all my issues I been having are gone. My 05 runs smoother than it had in YEARS. These plugs are much better then the old version and better built too, that you can tell when comparing side by sideRead full review...

Great original parts! Hard to find in the store but was able to get them here. Got an extra set for that reason and a great price!

Counterfeit Product

Counterfeit and lasted 5 minutes until they misfired. Pictures show difference in boxes from genuine (darker red box with correctly sized logo) vs counterfeit and 2nd picture shows genuine Motorcraft plug on left; phony plug on the right has smaller curve on casing. Read full review...

Ford 5.4 Ltr spark plugs

The pricing was good. and delivery on time. They have been in for about 1,000 miles and are performing well.

Good plugs

If you are going to change your plugs in a 5.4L Use FoMoCo plugs. I found the best price here. The engine no longer has a miss, and runs much better.
