ZZP LSx High Voltage Coil Packs (Round style)
ZZP's New High Voltage Round style LS Coil pack set of 8
LS2 LS3, LS4, LS7
We are proud to release this new product after years of testing and perfecting. They produce on average 15% more spark and have dyno tested before and after results netting 4 to 5 whp gains on a naturally aspirated LS vehicle. Turbocharged and Supercharged vehicles have netted 10+ whp gains. 15%+ more spark than stock. Which are very impressive numbers for coils. Many sellers just sell aftermarket coils making claims that they are better than stock without any real testing, but have never put it on a dyno to see actual differences. We don't release a product unless it produces better results than a factory OEM coil. With several dyno runs, we have tested many aftermarket brands that produce worse power than OEM GM coils, which in our opinion is unacceptable. This set of 8 coils will fit in place of the stock coils and connect directly to the factory connectors. Once installed, you'll have the power and performance of higher energy ignition. The Increased spark energy and voltage help improve the combustion process of the fuel mixture to create a more efficient burn. This results is improved throttle response, smooth idle, and quick starts, plus increased high rpm performance! These work fine also for totally factory stock vehicles.
There are many variations of LS coils even within the same make and model year, so please check your vehicle to see if you have the round style. Compare to our pictures or if they are stock coils they are Stamped 12573190. It will not fit vehicles with the square style coil. The connectors and the way they mount are different so you have to verify they look like the ones pictured.
We offer a replacement 1 year warranty.
