How many miles were on the plugs?

Jpc5519

I had a 05 XLT bought it with 164k miles on it. Changed the plugs around 190K because some cylinders were starting to miss, so I changed out coil packs and plugs cause it was throwing a code. Took my time, let them soak in some PB Blaster before carefully getting them out, ones in the back weren't fun. Didn't break any. Good luck!

Somebody told me they ordered a set off of amautoparts.com for like $50 or $60 bit I hadn't even looked on there to see what brand they are yet. I had planned on ordering from there

That's nonsense. I've had a $40 Chinese set of coils from Amazon in my truck for three years and they work fine, and if you read the 1,000+ reviews for them on Amazon, you'll see other happy customers.

I wouldn't call it nonsense. Like mentioned many times thus far, sometimes you can get away with cheap coils and sometimes they flat out fail almost immediately. You simply got a good batch. Some aren't so lucky. Same holds true for many other Chinese parts.

My advice is to buy two packs of them. If they each have a dud, you still have 14 working coils for the price of one OEM.

I just did mine. Take your time and make sure you have enough extensions. With the lisle tool, you have to have a deep well 15/16 socket (usually 1/2" drive) to get the extractor out so be prepared for that along with a couple of extensions. I found that one of the spark plug sockets that had the built in 6" swivel extension worked great because of the "wiggle room" it gives you. make sure to use anti seize on the new plugs and dielectric on the new COP's.

hopefully you don't have this issue, but do some research ahead of time so that you have an idea of what to do if the lisle tool won't get the plug out.
