MSDIgnition Coil

To begin id like to say how impressed I am with these ignition coils. I bought these ignition coils because I was having 3 cylinder misfires with my 2011 Ford F-150 3.5L Ecoboost. changed the spark plugs on the truck but the misfires wouldn't go away. after swapping the old ignition coils around I realized that they were bad and decided to go with these coils. Saved around $20 not going with the OEM ignition coils but I did like this design a lot better. the packaging was really good and installed them all in 20 mins. cleared the codes and took the truck for a spin, pushed the pedal all the way down and she ran with no hesitation at all. did that for a few miles and checked for codes when I got home but none were found. seemed like I got 2mpg more when I reset the fuel economy but again that was only for a few miles. so in the end, the 3 misfires were all gone and id says I was pretty happy with everything I will definitely update this post if anything changes.ps. incase anyone was wondering, cylinder 4,5,6 were misfiring when I changed sparkplugs and ignition coils at 155k miles and i have no clue when they were last changed.2011 Ford F-150 3.5L Ecoboost XLT.Update 3/29/21So far so good I haven’t had any problems what do ever and it seems to have solved my problem with the misfiring for good. Really would recommend these.

Coils work well. Truck now has no misfire under load, is more responsive to throttle input. Can't say I've noticed a fuel milage improvement as truck is usually pulling a trailer. Well worth the cost compared to OEM's which are $70 each at the dealer. Have only been running these for a couple months, but so far not issues.

Love the product and easy to install can tell difference when on the road

After spending $300+ you would think your getting a good product… nope. Nothing but cascading misfires 11 months in.

Runs like stock coils when they work, no performance gain. However the lifespan of these seem to be less than 2 years before issues arise. Right after the warranty ends. I spent $500 on these less than 2 years ago and now have to replace them with OEM ones anyways, waste of money!
