MAS Set of 8 Ignition Coils GDG511 GD511 FD508 Motorcraft Spark Plugs SP546 PZH14F For 2005-2008 Ford F150 F-150 Lincoln SP515

Excellent value! Installation is pretty simple for experienced mechanic. So far so good! Made a huge difference in my truck and drives strong like new. Still having p0303 code cyclinde 3 misfire. But truck is running good. Might be fuel injector issue. Will update once I fix. I recommend for everyone has misfire codes and or cylinder issues replace all of these at the same time and use the recommended grease to go with it. If you want to help the engine buy some Lucas for your engine oil on high mileage vehicles and it will help clean it out too!

Great price perfect fit . Runs like new

I'm spending a lot this month buying parts and tools for a Timing Chain job on my 2007 Ford F-150.My pickup has a 5.4L 3V engine that is known for Timing system problems related to low oil pressure.This will be a full rebuild using a Ford OEM parts kit here on Amazon. Ref: "FordTechMakuloco".This guy has a step by step set of videos that will help even us backyard mechanics to get this job done.He has a list of the needed tools and parts too. I'm well into this project now and am SOOOO GLAD that I followed his advice. I replaced the weak oil pump with a high volume pump from Melling and also pulled the oil pan to clear out old bits and pices of the plastic timing guides. This was a bit of a challenge as my 4X4 needed a front axle drop to get the pan out. As with the other videos, it became a dirty but smooth task.You can't go wrong following this guys advice, he has a first class operation.

Bought these with the plugs in a combo. just some things to note. The plugs were the wrong plugs, the coil connections are 10 thousands smaller due to the seal on the inside. you can get them to work by putting dialectic in the clip for lube. truck runs smoother. I would say they are not as hot as the previous coils, but I'm not trying to race it either.

I own a 2007 Ford FX4 crew cab with the 5.4 Triton 3v. Just like most 5.4 3v Triton owners, I was experiencing the 45-50mph shudder while applying light throttle while going up hills. There were times that it was idling a bit rough but once the throttle was applied, it would run great. The problem more than likely is that there is a miss in one of the cylinders. This is caused by a bad coil pack. Rather than spend $500 to have a Ford dealership tell you which cylinder, spend the money on this product and change out all of them. Chances are, if one is bad, the rest are near failure. My truck runs like new and I am pleased.
