Review on ECCPP Ignition Coil Pack Set of 4 Coils for Hyundai Santa Fe, Kia Forte, Optima, Sportage, Rondo - 2.0L, 2.4L, 4.6L, 5.0L - UF611 C1667 Replacement by Jeff Davidson

I had a misfire so I replaced the spark plugs and ignition coils (with these coils). I had the same fault on the same cylinder so I took my car to the shop to have it checked (I was concerned it might be compression issues). It turned out that one of the new coils was defective. Exactly the same as OEM. Yes, the coil has been checked. Those $40 coils cost me $120 to have a mechanic diagnose the problem and the misfires they caused could damage my catalytic converter. Buy non-junk casters (like these) and save yourself a headache and potential (very expensive) damage to your car. For the €160 they already cost me, I could have bought the original spools.
