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.

Sold in a set of 8.

Great product but not a direct fit

I absolutely love these coils. There is definitely a difference in responsiveness on the throttle in all RPM ranges! I feel more power both on top and low end! Definitely pulls a lot stronger on the highway. Also, it got rid of a slight misfire I had at idle. I still have yet to replace the spark plugs with AC-Delco 41-110s but even with the old spark plugs still in there the responsiveness feels great! I purchased these for my 2004 2500HD with a 6.0 gas engine. The coils did not fit directly into the OEM coil bracket but it was no big deal. I ended up grinding off part of the bracket enough for the coil to sit well enough. I was able to only use 1 screw to hold them down, however. I used washers to make them fit snug. I'm sure there are other ways of doing it besides mine. I plan on getting ordering an aftermarket bracket in the future

Were weaker than stock oem coils

Terrible. Spend almost $200 on these coils and they cut out worse than oem coils. Would love to send them back but they say in the return policy that electronics are non refundable and if you do send them back they may give you 50% less than ehat they cost back

UNDER CONSTRUCTION

A MEGA SQUIRT ECM IS BEING USED WITH THESE IGNITERS AND BEING INSTALLED ON A 400 CID SBC. THE GREATEST CHALLENGE IS FABRICATING A BRACKET THAT WILL NOT ITERFERE WITH THE PROFORM VALVE COVERS.

Great Coils

Didn't attach to the brackets I had. Found some nice ICT brackets and spacers that made these fit well with my ZZP plug wires in my truck. Beautiful coils and they perform very well!!!
