UF624 Ignition Coil & 97390 Double Iridium Spark Plug 30520-RN0-A01, E1124

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.

I bought this ignition coil and spark plug set as a replacement for my Audi, and it fit perfectly. Installation was straightforward, and the car started right up without any issues. The engine feels smoother and more responsive now. Solid quality parts at a fair price

This combo has significantly improved my car’s performance and efficiency.

It’s convenient to have both components in one package, saving me time and money. Improved Engine Performance: After installing these, I noticed an immediate improvement in my car’s acceleration and overall engine smoothness. The double iridium spark plugs provide a more efficient spark, which leads to better fuel combustion and improved performance . 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.

Came as advertised, fairly easy to install, and work great. The car is running smooth again.

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.

Excellent product, highly recommended. I’m not a mechanic but I try and save money by doing my own work. My gas mileage has increased, my Ram truck runs better than ever. Great value for your money.

Fit my 2010 Honda odyssey perfectly. Replaced an OEM coil and works great!

Needed to re-gap all the spark plugs as is normal. Just make sure you check and re-gap as needed pretty easy install on a Prius and it fixed all the misfire errors I was getting Prius has 325,000 miles. Also replaced fuel injectors.

Excelente

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

Excelente, le quedaron perfecto a mi altima 2.5 l

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

Excelente calidad, se noto la diferencia al cambiar las bobinas dañadas por las nuevas. RECOMENDADO
