Constantino Z.

They worked great in my 07 F150 5.4L. Second time doing plugs and coils in my truck, and this time was much easier. Make sure you do your research on this plug style if you’ve never changed them out yourself… prone to breaking off on the head unless you take some precautions and take your time! Either way, new plugs and coils went in smoothly and running like a champ again.

Amazon Customer

I bought these MAS Ignition Coils DG511 for 2 Reasons. The price was great compared to Motocraft and the 4.5 Stars were the the selling point. The Product is clean, no issues. The install was the same as replacing with OEM Motocraft. These have been installed since July and they are working great. I am very content with the product and the service the company has provided. I had asked the vendor/company a few questions and their response was fast. The company followed up with their response if I had any more questions.

Had these installed by a professional since the install difficulty was above my pay grade! The plugs are motorcraft so I expect no issues with them, the coils are aftermarket so I guess that I will have to see how they hold up. Right now the truck is running perfectly and I am quite pleased. Will probably update later as I put some miles on the job! The parts came well packaged with everything there as advertised!

The updated spark plugs and new COP's went in like a charm of my 2005 Ford F150, The truck now has the horsepower like when I bought it new. Smooth idling and no more bucking and jerking between 40 and 45 mph.

Before attempting to remove 5.4L 3 valve spark plugs watch videos on YouTube that give you precise instructions. Autolite has a good one. Also purchase the Lisle tool for removing broken used plugs. New plugs and COPs have added power to my 182,000 mile 2004 F150.
