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

These spools work and fit just like the original spools but are cheaper. I have OBD codes P0300 and P0303 on a 2008 Kia Rio 1.6L 4cyl. P0300 was a generic misfire code and P0303 meant cylinder 3 misfire. I found that the stock coils were failing because the valve cover gasket was leaking oil into the spark plug tubes and onto the stock coils. I replaced the valve cover gasket and replaced all four coils with it and the engine runs great again. All in all it cost me less than $100 and hours of time to do what would have cost the store over $400 to fix.
