Was wondering what everyone would recommend for new COP for a 2000 F-150 5.4L. I had trouble with them replaced one and then kept havin trouble so i tried the ones off ebay that people said were ok (bullcrap) had one go bad within a month so replaced it with a good old one i had and now where back to start another bad one-two have yet to find. This time moneys not holding these up (for the most part) i want something that i dont have to worry about going out for as long as i have the truck. This time it went out while haulin a car trailer with some stuff luckily only 5miles from home. Thanks in advance.

 

Did you replace spark plugs when you replaced cops? Bad plugs can cause cops to fail.

 

Yea put new plugs in, cop's i got off ebay were starting to rust and burn up from the look of the spring deal runnin in the boot ended up getn bwd's from oreillys came with lifetime warranty so at least if i have a problem i can take them somewhere. Was gunna go offline but needed me truck back asap. Without it i dont run.ha

 

WeaponX coils are supposed to be about as good as OEM
