    Been wanting to try these and I finally placed an order since the timing was right.

    As soon as I took them out of the box I felt the weight on them and thought, I have to compare them and sure enough, there was added weight.

    These are designed with the primary and secondary windings at the top versus the standard style.

    The test drive went without a hitch,
    smooth all the way with a cold start and actually required less rpms to get to speed all while doing it faster.

    I was using Duralast ignition coils and there was nothing wrong with them and they have a lifetime warranty.

    Duralast weighs 183 grams each coil,
    while the new ignition coil weighs 220 grams each coil, a whole 37 grams more coppers windings than Duralast coils.

    No fit issue with the bigger coils either.

    Im just gonna run these for a while and see the change, which I already felt and saw on the average mpg display.

    These should run cooler with more power and last longer than a standard prius ignition coil. 20251009_110532-1.jpeg 20251009_110052-1.jpeg 20251009_111038.jpeg 20251009_112658.jpeg 20251009_115725.jpeg

    How does the weight of the new brand X coils compare to an OEM coil?

    How much did you pay for a set of four of these brand X coils?

    The trq red coils are similar .. and there's another CO that advertised heavily . The coils look heavy duty a lil fatter
