Great Product
My vehicle was jerking under light acceleration at 40 + mph and the new ignition coil packs solved the problem! I replaced all 8 as its cheaper in bulk.
November 15, 2016
Great value
Truck was bucking under light acceleration around 45-50 so bad coils replaced all 8 and so far no bucking and no engine lights. Great price considering 1 coil alone can range from $45 to $90. Will update on how long they last.

2005 Ford F-150 Crewcab FX4 ignition coils
I have installed the ignitions coils and they are a perfect fit. I have used your instructional videos whether I buy parts or not from 1a Auto. I really appreciate the videos and how instructive they are. Thanks for such an easy to use system of instruction and available parts to complete the job!
February 28, 2017
Good parts
I like getting parts from yall cause yall always have the lowest prices but good quality parts.
March 5, 2017

Awesome product
Awesome product solved my problem in my Lincoln navigator I would recommend this to anyone
March 27, 2017
Fixed my issue
Great product for the price runs better than it was before Thanks A1auto
March 31, 2017
So far So good.
06 F250 5.4L developed a bad hesitation under minimal load. Knew it was either plugs or coilpacks. went with the easier and option of CP as the plugs have a reputation of snapping off in the head. Considerably cheaper through 1A Auto than anywhere else. Problem solved and at a fraction of the price.
April 23, 2017
Great transaction and product
Great transaction. Fast shipping. Will shop from them again!
July 11, 2017
Thumbs up
Im always hesitant about buying things online because you never know what youre buying but I can say Im very please with the ignition coils my husband and I purchased from this website. I will definitely be making another purchase in the near future.
August 1, 2017
COILS FROM A=1
I have now purchased coils from A-1 twice, my local supplier in Springfield Mo was bought out and now they ship freight from a warehouse in TN now having 2 purchase $300 to get free freight. Thanks A-1 will be stocking more coils soon.... we do a coil, plug tune for 59.95 a hole with A-1 coils,, thanks agin

Finally fixed my truck!
I have been dealing with my 2005 F150 engine having a skip or miss for about 4 months. I thought it was my transmission but when I started reading about others having the same issue online, I saw where the ignition coil was the problem with most of the F150s. Most of the sets of 8 coils were $200+. I saw these at 1/3 the price of others and decided to try them. I watched 1As "how to" video. My son and I installed them on Saturday morning in less than 1 hour and WOW!....no more hesitation in my engine! I have about 100 miles on these coils and it runs like new. 100% satisfied!
August 22, 2017
Coils
These coils were perfect. Direct fit and performed as advertised. Good price and fast shipping. Thanks
October 3, 2017
Work great
They work great 3 weeks and 1000 miles roughly later no problems at all.

Nice Deal!
Thank you for this product! Amazing quality for an amazing price! Your saying is true: "the best service on the internet". Recommend it.
October 11, 2017
Great service and outstanding value
Replaced all coils on my 2004 F150 triton. Worked as advertised. Recommend this distributor, great service, great price with free shipping. Will use for any additional needs.
October 22, 2017
Great product
I have a 2006 F150 and it was running bad. The rear was shacking bad when I went up hills, my mpg was at 11. There was no power in my truck. I replaced the the coils and the truck runs great. I recommend 1aauto to all my friends and family. I will be buying from them again. And the best part was the price, no auto part store could come close to the price.
November 9, 2017
Done for my truck just what I wanted it too .. easy to install great price.. great company to buy from
November 10, 2017
Made a big difference!
Truck had periodic power loss, intermittent engine light occasionally flashing. Hasn’t happened since replacing all the coils. Running great
January 1, 2018
my husband finally got to put them on his truck, had to wait for the weather to break, he drove it today and it seems to be better, he will know more tonight,
January 22, 2018
Worked perfectly
Worked for my 2004 f50 5.4. I was concerned because they were not the motorcraft coils. But they work great so far.
January 26, 2018
Very fast shipping
I am very happy to say it was shipped fast i just did not need them at this Time so i will keep them i had a Bad spark plug so changed all my plugs will hold on to the coils just in case !
January 30, 2018
Cheapest price
The price was cheaper than I found anywhere else. The installation video gave me the confidence to do it myself and it fixed the problem. I have only driven about 300 miles since replacing them or I would rate them higher.
January 31, 2018
Just what I needed
Perfect fit for my 2006 ford Explorer. Shipped fast and fit perfectly. Took about 1/2 Hour to remove the old ones and install the new. Fixed the stuttering issue I had. Shop rate was over $300.00. My mechanic said, order them online and install your self and save a bunch of money. I love that he is honest. I would recommend these to anyone.

Reliable parts without breaking the wallet
Ive used 1A Auto for more than a year now and have never been let down. There parts are excellent quality at truly affordable pricing. The ignition coils Im writing a review about are working perfectly. And Ive paid half the "stealerships" and chain auto parts store price. So what you have to wait for shipping. A1 ships fast and reliable. They will continue to get my business. My coils are a direct fit and my wallet remains somewhat full. Thanks again A1 Auto Parts
April 17, 2018
Working Great!
I had no idea just how bad the original coils had gotten. When you drive with less power and the occasional misfire and surging on hills you get used to it after a while. I replaced them a few weeks back and it runs like a new vehicle again. I am also getting 3 more MPG. Very impressed. TIP: get a 1/4" socket set and a good u-joint socket extension for getting out the coils on the passenger side.

Ford Expedition xlt el
My truck was hesitating whenever I accelerate. Advance auto diagnosed it and told me that it was my coil pack Number four. Then he explained Not to just replaced that one, replace all eight. He actually referred me to A1 on the low. The rating was great. So I gave it a try. My truck is driving smoother than before and haven’t had any problems within a whole month of getting them replaced
April 19, 2018
Big change in pulling power.
Easy to install and makes a huge difference. Would recommend this product to anyone.
April 20, 2018
Excellent Product!
Product was just as described. Shipping was fast, but most importantly it fixed my problem for a fraction of the cost that a shop would have charged! Would definitely recommend to others and most certainly will use A1 for future purchases.
April 30, 2018
Ignition coils..
First of all I can’t believe I got in this site so late! This site is freaking awesome, great selection and prices. Coils I ordered where the perfect match to originals. Easy to install w exception to coils in the back end of engine (hard to reach) but that’s just the way expedition is. Car running like new after coils were replaced! All of my autos are old so this website was godsend to get great parts at decent price! Will definitely order from here again

2007 Ford F150 5.4L
These are 3 times cheaper than OEM and just a bit more pricier than used, but these are new and they fit well. Check engine light for cylinder misfire is now fixed, would recommend.
May 18, 2018
Fixed my truck and didn’t break the bank
My truck was running bad and the engine light would flash if I accelerated on the freeway. I ordered the parts which were a fraction of the cost had I got them at the local auto parts store. It fixed the problem and if they last a good while then it was a great success. I’m happy with the results AND the prices. In addition to that it was free shipping. Can’t beat it.
May 18, 2018
Unbeatable deal to fix your shuttering 5.4
The dreaded 5.4 coil and plug replacement is smoothed over Big time time when you pay a fraction of the price for the 1aauto coil pack, rather than from the local parts store. Great quality and performance from these coils!! Gas milage is through the roof and the restored horse power makes my truck feel brand new!
May 30, 2018
Ford Ignition Coils did the trick
Code showed random miss fire for three cylinders on 2006 V8 Ford F 150 Lariat. Changed those three Ignition Coils and test drove. Result. Smooth as silk. What a relief!. Replaced others and test drove again. Smooth again.
June 8, 2018
Looks good
Was a good fit and seemed to be good quality worth getting these to save money verse motorcraft ones.
June 25, 2018
Got the coils in 2 days after I ordered them which was great, and of course the instal was easy. They seem to be working great so far! And you cant beat the price compared to the other parts stores that want 250$+
July 16, 2018
Perfect!
I was leary because they were so much cheaper than the motorcraft coils, but they look identical and so far they make the truck run like new again. Shipping was very fast as well.
July 17, 2018
OEM fit.
Customer had a Random misfire on his 2007 F-150. I ordered these and the Random misfire code went away. Eight of these coil packs for the price of one. Customer is very happy and so am I. "Ed".
July 17, 2018
Inexpensive ...But, work!
I purchased these coils for my 06 Ford F-150 Super Crew FX4 that was having sluggish performance problems. These coils (the cheapest I could find) coupled with new E3 spark plugs and a VVT solenoid repair kit completely fixed the problem. The coils may be inexpensive compared to other brands, but they work! Drove the truck home from the repair shop and it was like driving a vehicle with 100k fewer miles on it. I highly recommend to others.
July 24, 2018
Factory Quality
I bought these over a year ago. Since the installation and numerous trips, stop and go traffic, and countries start ups I havent had a single issue. The price comparison alone is worth more than the second thought of should I buy this. You should buy these.
July 30, 2018
ignition coils
I wanted to thank you for your great service and timely delivery of my coils. A rep double checked to make sure that I had the correct coils and everything worked great. I will surely order from you again. Thanks again, Mack
August 14, 2018
Sent the wrong part but took care of it quickly.
Ordered these ignition coils in a pack of 8. I got through installing of the and grabbed the last two from the box and they were the incorrect parts. I called on a Sunday night and they sent me the correct ones by Wednesday. So it was taken care of easily and quickly. Just an inconvenience. The parts were less than half the price of autozone so we will see how they last. So far so good.
August 18, 2018
Great product

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Do I need to replace spark plug cable too?
Joe S September 9, 2015
This item goes right into the spark plug , the coil packs do away with the cables
Charles A September 9, 2015
No, these coils go directly onto the spark plug, there is no cable.
Jonathan C September 9, 2015
Each ignition coil is a complete unit that fits directly on to the spark plug, no cable is required.
Peter C September 9, 2015
No. The cable is a six inch long boot that comes with the coil, already attached, and ready to install.
Alan K September 9, 2015
There is no spark plug cable. This is electronic ignition. The coil packs replace the distribuator that used to be on old systems.
