Review on Maximize Spark Efficiency with NewYall Pack of 6 Ignition Coils by Malik Munns

Bought a set of 6 and 1 was faulty returned 6 coils when only one coil is faulty and told them I will just buy elsewhere in the future because if anything sounds too good to post Being true it's usually because this is the second 6 pack of coils I've bought here last year and the coils will probably never go bad, I've had 3 failures, the first order should be known, now I'm ordering one second time on amazon through a different seller and blown but there will be no third, i just wanted to exchange a defective coil but was told i have to exchange them all, still wondering at least amazon said they would take my card or return a defective coil and then I wouldn't have to buy new or used and I'd have a weird set unhappy with everything but what the T eufel i can do, just live and learn F YI
