My Maytag Neptune had the original 2009 wax motor and had burned the resistor and triac.  Replaced new Wax Motor and also the resistor and triac.  All is working good now.  You know that you have the latest updated Wax Motor when the shaft is black.

CDI box failed, but that was due to electrical bugs in my scooters system wiring.
It's all sorted now and the Orange Coil Wire is still going strong.
(one thing though, do yourself a real favor and buy a proper NGK spark plug #C7HSA, or Iridium CR7HIX, your bike will thank you)

I bought some cheap coils two years ago that lasted about 30k. The original motorcraft ones lasted over 100k

The price was fantastic
Don't waste your time on the cheap ones. It's a three hour job to put these in, so make sure you use the motorcraft coils

My 17 year old Gold Series Lawn Boy surprised me when, for the first time, it would not start. A quick check pointed to a bad ignition coil. Armed with the Model/Serial number I started looking online to determine what this part might cost me at one of the local small engine repair shops. I must say I was a bit surprised to discover that this coil sells for around $108. Obviously I did not want to spend that kind of money on an old mower so my next check was on Amazon. I found this coil for about $25 (with free delivery via Prime) and ordered it. I was pleasantly surprised at how fast it arrived. Installation was a snap and my old mower started up on the first pull. Very happy with my experience and I hope this coil lasts as long as the original one did.

No fit problems once I plugged the right cylinder to the right coil.  The bigger wires don;t fit in the stock hold downs anymore, so don;t forget to pick up some aftermarket ones.

I bought these with new coils when my engine started running rough.  An old coil had stopped working, can be caused by old spark plugs I hear.  Working  great after change out.

I recommend the coil-on plug set. It took some time to install, but it was an effort that justified its outcome.

So the spark plugs were the proper replacements and they seem to be working fine but so far in the last 1000 miles two of the coils have gone bad. And it appears because they came in a set I can only replace the set. Not about to remove all the spark plugs and they are not deedective. Would just like to return the spark plug coils. If I can just return the coils please let me know.

My son bought this for his 2006 Volvo XC90 T6. The car started running rough and through some troubleshooting through texts we were able to identify the issue as a non functioning coil. He ordered this from Amazon and installed it and the issue was gone. Price wise it wasn't the cheapest but it also wasn't over priced. Being a Delphi product I am hoping it will perform as well as an OEM Volvo coil. If it doesn't I will update this review.

They worked good for about a month or 2, customer came back complaining about the engine light again. #2 and #6 coil stopped working and I had to replace under warranty. Will try to get with manufacturers for some help on issue

one of the coils was broken completely into. The other five worked fine. I was able to use one of my old ones in place of the broken one. I didn't bother to send the broken one back.

The coils stopped the misfiring and slow response. Just replaced them and the car runs like new.  Gas has improved.

I have a 2006 Ford F-150 that was jerking when slowly accelerating around 45 or 50 MPH.  I had the spark plug changed about 30K miles ago, so I thought I'd give a new coil pack a try.  For the cost of this set, I thought I could not go wrong.  This was the first time I had ever changed coils out before.  It took me about an hour and a half and a few minutes watching a YouTube video, but I got it done.  The hardest part was reaching the coils in the back with my big hands and the small area to work in.  I am happy to report that my truck now runs smoothly without the jerking.  I am very happy with the results.
Update:  After about 3 weeks of use, I've already had one ignition coil go bad.  I was just driving at highway speeds and noticed my truck started missing.  I eventually checked the codes and found cylinder 1 was missing.  I had to buy one ignition coil from the local auto parts store which actually cost more than all 8 of these coils together.  Problem solved.  I have to change my review to 1 star.

Update:  I contacted the seller, and they shipped me a replacement ignition coil.  So at least I have a spare now.  It's been several months since I installed the coils. All the other 7 ignition  coils that are still installed are still working great.  Updating the rating to 3 stars.

Installed this new cap/rotor combo and car wouldnt start and for the life of me i couldn't figure it out since i had changed plugs, wires, dizzy o-ring all at the same time, but it ended up being the rotor that was the culprit. gonna go OEM rotor to replace the old OEM one. probably will just get all OEM next time. usually i don't have a problem with OEM-replacement but this is one of the few times ive been proven otherwise.

I was excited and install it as soon as it came in less than a week my car started to Shake while I was driving I pulled over disconnected the wire individually from each coil while running came across these ones pulled out the wire and nothing it did not shake like how it was supposed to if the coil is good That's when I knew the coil was bad luckily I kept the old ones changed it went home about three days later my engine light turns on it's p0304 that's where the second coil was located I could already start to feel that it's going bad switch it around to see if the same code would pop up now it's a p0303 where I switch the coil to went to O'Reilly Auto Parts purchase 2 more new ones for $70 each now it runs great
