Review: Good quality replacement, car runs smooth again - 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
Review: Works great on a 2014 Mazda 3i Touring 2.0 - 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.

### ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ Great Performance for My Hyundai Accent!
*by J***Y on January 8, 2025*

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: Complete Package: The set includes 4 ignition coils and 4 double iridium spark plugs, which is everything I needed for a full replacement. 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. 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. It’s affordable, easy to install, and delivers noticeable improvements in engine performance and fuel efficiency. Whether you’re replacing worn-out parts or just looking to enhance your car’s performance, this set is a great choice. Highly recommend for Hyundai Accent owners!
