AMPEFI put together the best and most powerful ignition upgrade kit available for your GM LS engine, and it’s a complete drop-on affair.  MaxSpark PNP is next level with more spark energy than the stock LS ignition coils by a longshot.  If you want more power, cleaner idle and cruise that just ‘feels smoother’ while maximizing fuel economy at the same time– you’ve come to the right place.
The MaxSpark PNP LS Ignition Coil kit is not ONLY a performance king– it’s dead sexy in appearance too from the Billet Aluminum Brackets to the LS Wiring Harness that’s better fit, finish, and quality than the factory GM piece.  It’s function AND form in one easy to install kit.
 
YES– You can use the MaxSpark PNP LS Smart Coil Ignition system on your LS Engine with the factory Engine Control Unit, or with any aftermarket ECU, whether it be MS3Pro or any other system out there that allows you to configure ignition outputs, dwell, etc.
The Hottest LS Ignition Coil System available
This is a full Plug and Play solution to add incredibly strong ignition to your GM LS Engine.  There is no hotter inductive LS Engine Ignition on the market.
Benefits include eliminating misfire due to spark blow out, smoother idle, better throttle response, and more power.   With MaxSpark PNP you can TURN UP THE BOOST!!!  
You’ve got the ignition to handle it now.
This ignition is hot enough for any engine modifications you have planned, from naturally aspirated or forced induction, race gas, methanol or ethanol, high compression, turbo, supercharged and nitrous.  Crank the boost on that LS; we’ve got spark covered.
 
Easy to install – everything included
 
Package includes everything you need: Dead Sexy Plug and play harnesses, Billet Mounting Brackets, IGN1A smart ignition coils, spark plug wires, and hardware.  The installation couldn’t be any easier.
A full, high quality installation guide is included [download].  There is no guesswork.
Kit plugs directly into a GM LS engine harness.
Billet brackets bolt right to the valve cover.  This mounts our IGN-1A ignition coils directly to factory LS valve covers, similar to stock.
Our harness does 90% of the wiring for you.  Only bit you have to do yourself is the main power wire to the battery, and the switched power.  We provide guidance in our docs (see documentation tab below) and in the video below that walks you through it all!
Connects to factory ignition coil connector on engine harness, making for the easiest PNP installation possible.
You can probably install this kit in about an hour or so.
 You WILL notice the difference.
 
No more spark blowout – allowing you to make ALL the horsepower.  More complete combustion leading to more power.  Better fuel economy and even lower emissions are all possible.  We’ve had multiple customers report smoother idle and cruise, and another customer recently reported being able to lean his fuel table out a bit to maintain the same Air/Fuel Ratio as with the factory coils– suggesting these coils are more completely burning the mixture, getting ALL of the power out of the fuel, while reducing fuel consumption and likely having a positive impact on emissions even!
