These high voltage coil packs will supply a stronger spark which will allow you to run a larger gap that will improve fuel economy, driveability, and HP capability. Not an earth shattering difference but a small gain. Definitely well worth the upgrade if you're replacing your coils.

United StatesDefinitely made a huge improvement over stock! Quicker throttle response and faster acceleration. Matched with bigger plug wires and new plugs it helps immensely!
United StatesThanks for the upgrade works as it should. Happy with my purchase it's a no Brainer cost is cheaper than acdelco. Anyone would be dumb not to buy one instead if oem. I'll be buying other ZZP parts in the future!
Australia3rd attempt at getting a picture to show up with a review... Starting to think that my picture isn't going to work because I installed this item on an Australian Holden Statesman...
United StatesI am very happy with the set zz performance coils. I did notice a little more pep on cold start and taking off. I also installed a set of 10.5 mm wires and new plugs at the same time.
