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.

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!

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.

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.

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

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.

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

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.

Reliable parts without breaking the wallet
I've 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 I'm writing a review about are working perfectly. And I've 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
