    Coil Packs - Best/Worst brands

    So, one of my coil packs went bad. There is a large variation in price between brands.

    What are the best and worst brands? Any evidence?

    I remember this.

    If I needed new coils, I'd go with Hitachi.

    The worst coils I remember hearing about were from autozone and the other big chain supplier in the US.

    That's where they were from at the time when they were bad right out of the box.

    I purchased brand new ignition coils from Mazda here in Australia about 3 years back, and it has "HANSH/N" and "DSC-1500" embossed near where the ignition cord plugs into it. The coils I replaced also had the same embossing, and I know the full history of the car since new, which was always serviced at a Mazda dealership. Have seen some coils that have DSC-1500 printed on them, but I'm lead to believe they're not the same/genuine Mazda.



    I don't know what brand they are, and Mazda could not tell me either. It has no brand name such as Hitachi or NGK anywhere on them. The old set I replaced had done over 80'000 kilometres (just under 50'000 miles) on them, and were still fine. I replaced them as a precaution.


    A quick Google of 'HANSH/N ignition coil' gives me results that also leads be to believe they're genuine Mazda.

    This is what I get for OEM coils...



    I'm getting $116.27 for each coil.

    Looking at this again, it looks like part #1 includes parts #2 & 3, so $82.26.

    I got these back in november from amazon and so far they been holding up just fine. Before these I got a set from rockauto (cant recall brand) and they lasted me about 80k miles.

    I can now confirm the photo I posted above is of a genuine Mazda coil. See photos below.





    If it has 'HANSH/N + DSC-1500' embossed on the coil, it is genuine Mazda.

    i've had luck with the autozone ones for 60k ish miles but replaced them while trying to troubleshoot something. replaced them with beck/arnley coils and they've been fine so far for about 3-4k miles.
