Perfect that they sell them together. Installed myself in one hour. Engine runs smooth now. Look like OEM coils. Fair price.

Worked perfectly, was easy to install, and solved my issue with power dip and no more alarm code on my dash. You’ll need a socket set with a long extension for sparkplug removal, but otherwise it was plug and play

Amazon to the rescue again. Overnight shipping and my Ring doorbell went off shortly after 4 am announcing their arrival.
Immediately my son’s 2017 Kia Forte ran better. While I am not sure of the quality of the plugs and coils, they seem to have resolved his hard starting, hesitation and misfire he was having. For the price, if they last a few year, it was a cheap tune-up. Easy to change, while the most difficult part was getting the clips of the old coils due to it being 28 degrees out when we changed them.

Perfect Fit and Great Performance!
These spark plugs and ignition coil worked perfectly for my car. Installation was easy, and right after replacing them, the engine started running smoother and with more power. No more rough idling or hesitation when accelerating. The quality looks excellent, and everything fit exactly as it should. Great value for the price — highly recommend!

Purchased for a 2014 Mazda 3i Touring (2.0L). The car has 212,000 miles on it. Cylinder #2 had a misfire and was giving an P0302 code on an OBD2 scanner.
Everything came well packaged, ordered on Thursday – Delivered on Saturday. Everything fit correctly and worked properly.
The plugs were a proper fit, pre gapped correctly, and seem to be good quality. The Coil Packs look identical to the stock OEM units. Plugs and Coil Packs were both plug & play right out of the box.
Easy to install these in your driveway in 10-15 minutes. I also bought a can of CRC Mass Airflow Sensor Cleaner to spray clean the MAF Sensor (two screws, remove, spray let air dry 3x (*don’t touch the sensor or wipe it*), reinstall). I also cleaned the battery terminals and cables applied anti corrosion gel and washers. Air filter and oil were already changed recently so not needed.
So far after a couple hundred miles everything seems great, car runs better, idles smoother, gas mileage is up 4mpg.
Auto parts store wanted $150+ per coil pack and $25 per plug of this same type. So this saved $630+ by purchasing these instead. If any problems pop up I will update my review but so far everything is completely positive.
Hope this review helps.

This ignition coil and spark plug set is excellent quality. My car was shaking and losing power, and after installing these parts the engine immediately ran smoother and stronger. The pieces feel sturdy and well-made, and the fit was perfect for my Nissan. Great performance upgrade for a great price!”

My 2015 Jeep compass was jerking on acceleration due to a cylinder misfire. Replaced the spark plugs and ignitions and that fixed the issue right up

I recently purchased the UF652 Ignition Coil & 93815 Double Iridium Spark Plug set for my 2015 Hyundai Accent, and I’m extremely satisfied with the results. This combo has significantly improved my car’s performance and efficiency. Here’s my detailed review:
What I Loved:

.
Durable and High-Quality Materials: The iridium spark plugs are designed to withstand high temperatures, making them perfect for modern engines. They’re built to last, which means I won’t have to replace them anytime soon.
Fuel Efficiency: Since installing this set, I’ve noticed a slight improvement in my car’s fuel efficiency. The better combustion provided by the iridium plugs seems to be making a difference
.
Easy Installation: The parts were easy to install, even for someone like me who isn’t a professional mechanic. The fit was perfect for my Hyundai Accent, and the process was straightforward.
Cost-Effective Solution: Compared to buying these parts individually, this set is a fantastic deal. It’s a high-quality, affordable option for anyone looking to replace their ignition coils and spark plugs.
What Could Be Improved:
The only minor downside is that the packaging could be a bit more secure to prevent the parts from shifting during shipping. However, everything arrived in good condition, so it wasn’t a big issue.
Final Thoughts:
The UF652 Ignition Coil & 93815 Double Iridium Spark Plug set is a fantastic upgrade for anyone with a 2012-2020 Hyundai Accent.
