The Best Coil on Plugs for a Ford 3V Engine

One of the biggest wastes of money is buying "performance" Coil on Plugs aka COPS.
In this video, I share how to "rebuild" your OEM COPS using a spring and boot kit. While this focuses on Ford's 3V engines, this should transfer to any other vehicle with Coil on Plugs as long as you can buy replacement Springs and Boots.

By cleaning the COPs, you are reducing your chances of encountering a misfire as the COPs rarely fail.

I know this is slightly old but…to anyone else out there… I just finished my spark plugs and was gonna go with all new coils also. I saw this video and decided to do it…followed the instructions to a T…and it worked. Misfire on #1 and #4 codes, random misfire code, and coil circuit H code. All fixed. This man saved me many hundreds!

I never leave comments but just had to here. This saved me. Exactly what I needed and fixed it up in a bit over an hour. Just test drove my 2007 F150 5.4 and the hesitation/ stuttering is gone. This is legit. Thank you!

My Expedition drivetrain felt like it was going to rip out from underneath the vehicle. Did this and now it is smooth as butter. Thanks Johnny!

Great tip Johnny. The engine light is staying off and the miss is gone.

Excellent info. I wish more people could see this video, very helpful. Thanks.

The amount of people paying 50+ dollars for a new coil over plug or even $100 if you take into a garage just to replace an entire piece that needed a good cleaning, would be staggering.
Well done Johnny!

I enjoyed watching this video… I have never replaced a coil on plug before. I’ve replaced countless ignition wires and spark plugs on older vehicles, but I’ve not replaced any on vehicles with coil on plugs I was looking at one on my car today, and I was not willing to pull up on the boot because I was unsure how the assembly went together. Thank you for your video… It was very helpful.

Great video. I'm turbo'd and experiencing spark blowout. I am going to do this when I re-gap the plugs.

I own a 99 f250 SD and I use the rifle bore cleaning brush and cordless drill plus contact spray
cleaner.
Works every time.👍🏽🤑

Very good video! Very helpful! You saved me huge money!!! $97 per coil that I was gonna get, a simple cleaning and bam! Truck runs great! Awesome video thank you for taking the time and making/helping people save money and become a little more smarter!!!!😊

[Samhain]

I'm going to try this today...good tip.

[thewholls]

Good on ya mate

good video, I’m definitely gonna try this. It also occurred to me you could clean that spade terminal with an emery board the ladies used to file their nails with might work a bit quicker……..

Also on YouTube, there’s several videos showing how to test resistance of coil on plug using a primary test and a secondary test via a multimeter while it’s out it’s probably not a bad idea

All the best from Melbourne Australia

Sandpaper nail files work great for this sort of job.

I've got the powered by Ford intake cover and the matching fuel rail covers that help keep water, dirt, & other road debri away from the cop area. Im sittN on about 45k miles on my 06 GT so its about time for her first plug change.

[chargeron]

Great video and thanks for sharing! Will try this out for sure!

2010 f150 xlt 4.6 3v. Can i use some fine sandpaper to clean the corosion? I have the shudder at 50mph, im ordering boots and springs now

[missyidontgiveacrap]

Can you just clean the original spring instead of buying new ones? If so, what would be the best way?
