Full Set of Six Powerful Accel Coils for your EcoBoost F150

Getting the most out of your 2011-2016 F150 3.5L EcoBoost V6 means ensuring that you have a clean and powerful spark so you get a clean fuel burn for maximum power. The Accel Supercoil Coil Packs drop right into place of the factory coils and feature an advanced design that provides your powerful truck the extra ignition power it needs to get a clean burn so that you see improved power, fuel economy, and general running. The Accel Supercoils work with basically any stock-replacement spark plug, are OBD-II compatible, and don't require any special tuning or PCM programming for operation.

Finely-Tuned Windings with Advanced Bobbins and Shock-Resistant Expoy Coating

This full set of six coil-on-plug ignition coils come with plug-and-play connectors and complete boot assemblies that install right on top of your truck's spark plugs. Each plug is manufactured using advanced bobbins and specialized silicone magnetic steel cores. The windings of each coil are optimized and tuned to provide excellent power and turn ratios that ensure optimum spark. High temperature expoy coatings help the coils resist shock, vibration, and heat so that your truck runs flawlessly no matter its application. This version of Accel's coils come standard with a cool blue finish that looks great in your engine bay.

2011 F150, ecoboost

I kept replacing cool packs, sometimes 2-3 a month. After buying these, the missing and shuddering has ceased and the truck is solid. Best thing I've ever bought

2011 F150 Eco Boost

Very good product. Fitment was great, and it arrived quickly. It is a less than 30 minute install. The hardest part is pulling out the original coils since the lower boots can get stuck on the spark plug. If that happens you just need a needle nose pliers to pull them off. I purchased because the 2nd factory coil had failed in two months on my 2011 ecoboost, so I decided to change them all. Very happy.

2014 Platinum

These started failing one by one after about 8k miles. The plastic body became brittle and the metal plug contacts inside the housing deteriorated until it barely made contact with the plug. Which of course caused horrible misfires. I don't recommend them.

Great product, seem to be very well made and performance is much better over the stock coils that seemed to be getting tired after 100k miles. All in all i would recommend this product to anyone that has done anything performance enhancing to there ecoboost. Seems to help fight the idling issues and hopefully will be even better with the new catted downpipe and tune coming at the end of this week.

Will these work in the non eco boost 3.5l ford

Asked by: J-man - 5/25/2020

They will not. Accel does have a version for the naturally-aspirated 3.5L Duratecs. Just give us a call directly at 623-434-5277 to order.

Saw a video where Ford recommended a new boot on the coil..Motorcraft part # WR-6135...do these Accel coils match up to Fords boot?

Asked by: TK - 1/11/2020

These coils come with their own boot that is equivalent to the OEM part number. No additional boots are required.

What is the reliability of these coil packs?

Asked by: Brandon - 1/6/2019

The general reliability of these coil packs seems pretty good. That being said, they've only been out about a year and a half, so it's tough to gauge their long-term reliability as of yet.

What is the difference between the different colored coil packs?

Asked by: Doug - 11/23/2018

For Accel's coil packs, just the color. Their internal design and performance characteristics are all the same.

Other websites list these coil packs fit 2011 thru 2018’s f-150’s and they have a 3 prong connection. But you list them only fitting up to 2016. Are these coil packs a 2 or 3 prong connection? If they are a 3 prong connection they should fit up to 2018.

Asked by: Tom M - 10/13/2018

The amount of prongs is only one factor in regards to fitment and function of these coilpacks. The Ford OEM part numbers for coil packs are different between the 2016 model year (DG549 or BL3Z-12029-C) and the 2017-2018 model years (DG560). They will not work on a 2017-2018 F150 3.5L EcoBoost, we found out the hard way.
