Ignition coils
Charles
April 24, 2017
These coils are very similar to the factory originals. I was able to remove the old ones, change the plugs and install the new ones in just over an hour. I matched them with iridium plugs and my gas mileage increased by a couple miles per gallon. No sputtering when hitting the throttle, quick and easy start-up and backed by a very nice warranty. Overall, very happy with my purchase and look forward to not having to replace this part for many years to come. What more can I say, quality at an affordable price. Doing business the way it should be done. Great job A1 Auto.

This was a great purchase, parts all went in as they stated and the video made it easy to save the 300 dollars they wanted to put them in. I would highly recommend if you are handy that you try 1aauto for your next repair, shipping was free and parts came earlier than they said.

I got these coils replaced in like 30 mins with common hand tools and now my truck runs brand new, the engine runs a lot smoother and my gas mileage is better. Also for only 119.95 and you get 6 coils!? That is a crazy good deal, I will definitely be buying more parts from here.
Great Service

I love this company. They truly believe in making their customers feel as if nothing else matters at that time. I did have a issue that was taken care of right away and thanks to Joshua it all was resolved. I will continue to be a return customer for the quality parts and the customer service that sets this company apart from the rest. God bless. Mark R. Fairfield twp. Oh.

I was skeptical on this purchase, but i took a chance and wow! This product fit perfectly and worked just as good as factory. This is the start of a good relationship between me and 1A auto. Also on another note, I really enjoy the YouTube videos they produce, not only selling the product, but having a step by step on how to fix it

These were a fraction of the cost from autozone. The parts are nearly identical to the factory ones I replaced. The fitment was exact. I wasn't experiencing a misfire, but I knew the 4.2 had an issue with failed coils so I replaced the coils and plugs proactively. Therefore, I can't say that my SUV runs any better, but I did see fuel mileage increase. Shipping was fast and free.... that's always nice too.

I would highly recommend these coils as they were a perfect fit and excellent quality replacements for the originals at a much better price. Install was a snap thanks to the 1A Auto videos and it brought new life to my old 2004 trailblazer. Shipping was super fast and customer service is always great!
Worked perfectly

Bought them after reading the reviews. Was not disappointed. The coil packs fit perfectly. No problems with the clips not fitting. My 2004 Envoy runs great again.
Good for the cost

the fit good. works okay but not great for pick up. My SUV is hesitating to accelerate above 65mph. I may have to get the branded parts to get the acceleration i was expecting to see. Over all good the cost i got.

I was a little concerned with the much lower than OEM price on these, but all 6 worked with no issues and seem to be quality made. The misfire issues I was having have completely resolved and I am very happy with my purchase.

I love everything about this site. If I would have gone to the auto parts store I would have paid $65 to $70 each for one coil. Here I paid $122.95 for all six coils. My car runs great. This site saved me almost $270.

As an independent woman, I try to work on my own vehicle as much as I can. I was a bit nervous of doing this work on my own, as it was my first attempt. The parts came and the video was incredibly helpful. My old beast is now purring like a kitten and I probably saved $500 or more by doing it myself. Thanks!!

I was pleasantly surprised with the quality of these coils. I could not tell the difference from the AC Delco other than the PRICE!!! I have had them installed for more than a month now and the vehicle is running great. I hope that they last as long as the originals because they lasted 196,000 miles.

The price for a six pack was what some parts stores wanted to charge me for one; for the same part! Excellent price, the parts fit like a glove and work properly. The ordering was easy to find the parts- ignition coils-for my trailblazer. They came a day earlier which was great, packed safely as well. Overall, great service.

One coil went bad on an 05 Envoy w/127000 miles, so l decided to change all plugs and coils. The product arrived quickly. Only time will tell, but it's been three weeks and all is well.

1 damaged, 1 dead ignition coils have a bolt that is built into them. One of the six the bolt was bent and unable to be installed. A second one was completely dead and would not work at all.

August 12, 2020
2 of the 6 coils received were defective - i had to replace the spark plugs and then put my old coils on - i tried calling 1A but was on hold forever - went to return online but it was not the whole part, I am extremely busy right now so very inconvenient :( wish the packers would have checked the parts when putting them in the box as the sleeves were so loose

04 trailblazer 177,000 started missing bad and I just changed plugs a month ago. Pulled codes, which said misfire. Bought these took about an hour to do whole job, easy youtube videos. Been running about a week and my car runs better with these coils than the stocks ever did. More responsive and smoother idle. Hopefully they last. Would recommend!
Perfect Fit! Top notch quality!

Engine ram rough and hard to start. The code read 1 bad ignition coil but I replaced them all since the car had 150k miles & i didnt want to do it all again in a month... This was an easy install.. it helps access to a shop but not necessary. Just find a video on line.. While your in there... Make sure you check & clean or replace your plugs..

The company went over and beyond to help me. The parts were supposedly delivered by the carrier but they did not arrive at my home. I called A1 and they shipped replacement parts (at no expense to me). The original shipment arrived the next day. I called A1 and reported this but they had already sent replacement parts. A1 is a first class operation.

Do not see any markings on the part - the box references Vendor #V0193, so maybe you can ask 1A Auto's customer service to look it up? Sorry I couldn't be of more help.
