Review on Ignition Coil Pack Set of 4 - Replaces 27301-26640 - For Hyundai Accent, Kia Rio, Rio5 2006-2011 Models by Aaron Ali

I was really attracted to the price. I have a 2006 Kia Rio5 that had a nasty backfire. I finally settled on ignition coils but other online stores would take too long or be too expensive. So I found them at Revain, fast shipping and reasonable price. I installed them in September 2018 and they worked great! No more misfires, no more power loss, problem solved! For now. Fast forward to January 2019. I only use the car for city trips (my distance is about 7 miles one way) and I drive very modestly. However, after less than 10,000 km I have misfires again. Checked the spark plugs, pulled code P0301 (Cylinder 1 misfire) so I swapped the cylinder 1 coil with the cylinder 4 coil. Run the code and it came up P0304 (Cylinder 4 misfire). I had high hopes for them, but getting through just a few thousand miles is a drag. On the other hand, you get what you pay for, so I think they served their purpose, albeit for a short time.
