Ignition - ZZP LSx High Voltage Coil (Square Style)
After the resounding success of our round style LSx ignition coils we now produce and stock the square style. These 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 square style. These will not fit vehicles with the round style coil. The connectors and the way they mount are different so you have to verify they look like the ones pictured.

Industry best 2 year warranty. 

Sold in a set of 8.

Fits 4.8, 5.3, 6.0, 6.2, 7.0

Nice look with good performance

Bought these to replace my stock coils as half had huge cracks in them. This have a good look to them under the hood and perform equal or greater then stock.

Great coils

Only have about 500 miles on them, but exact style I needed for my car. Hopefully they hold up as well as oem coils

Didn't quite fit

They bolted on the brackets just fine but I noticed after plugging them into the harness the groves on the inside of the female plug on the coils was not open enough for my male plug on my wiring harness and they was hard to plug in and if I unplugged them they broke the plug on the wiring harness oh well if I ever need to remove the coils I'll just unplug the big main coil plug on the harness and btw installed on a 2009 saab 9-7x aero ls2 engine
