MaxSpark PNP LS – IGN1A Smart Coil Ignition Kit for GM LS Engines

5 out of 5 based on 1 customer rating
(1 customer review)




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.

And 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.

MaxSpark PNP LS – Unboxing and Installation

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!

IGN1A versus Stock LS Coils - IGN-1A Smart Ignition Coil from AMPEFI

This is at 13.5v and it leaves every factory LS coil tested in the dust.  Wanna take it further? The IGN1A will handle a 16v system charging at 18v reliably, allowing them to charge even faster at a much steeper slope, and OH MY GOSH do they deliver the fire.  I had one customer make the statement they could burn water….  This is one bad mamajamma….

The legendary IGN-1A Smart Ignition Coil

The MaxSpark PNP LS Ignition Coil kit utilizes the AMPEFI IGN1A smart ignition coil packs that produce over 100mj per spark event.   That’s nearly 2X more energy than the leading competitors.

These coils are MUCH hotter than factory LS ignition coils.  It’s not even close.IGN1A Smart Ignition Coil from AMPEFI

Wiring Harness Quality is Top Notch in fit, form, and function

  • High quality, plug and play LS wiring harness features OE-grade connectors, techflex flame retardant loom, and TXL high temp automotive grade wire.
  • All wires are color coded.
  • Ignition Coil connectors are labeled with custom printed heat shrink to help ensure you install it right the first time.  Plug ‘Coil 1’ into coil 1, repeat for coil 2, you’re almost done….
  • Wiring harness is designed to be tucked for a professional and appealing look when installed.  But it’s so dead sexy you might not want to hide it!
  • Waterproof automotive grade relays and fuses allow for minimal voltage drop.  Both 12V power and ground connections to the coils are greatly improved over the original factory wiring.  This allows for much less voltage drop, thus much better ignition performance.
    • The ignition high current is routed through this new relay, instead of through the OE main relay, allowing these ignition coils to get full current for maximum power all the way to the spark plugs.

What’s Included in the Box:

  • Billet Aluminum Coil Brackets designed to fit LS Engine valve covers.
  • Ignition Coils are triggered by factory style sequential coil-per-plug control.
  • PNP LS Engine Wiring Harnesses for passenger and drivers side.
  • Custom Magnecor KV85 Race Spark Plug Wires included.

We did our homework to try and ensure this kit works with most LS engines possible.  We’ve only found challenges with LS9 and LSA engines that would require a different mounting approach and harness.


Perfect for naturally aspirated engines, turbo engines, supercharged engines, mild, medium or rowdy camshafts and any other modification that can benefit from maximum ignition power.  You get the fuel and air into the cylinders, and let MaxSpark PNP LS Ignition LIGHT YOUR FIRE!


There’s no hotter inductive ignition available

If you have been looking for the best coil on plug, or coil per plug conversion ignition system is for your GM LS engine, you’ve found it.

These IGN1A Smart Coils are known far and wide as being the hottest ignition coils available.  We and our customers have used them on everything from National Champion Solo cars to Drag Racing monsters and Land Speed cars breaking 300mph on the Bonneville Salt Flats, with just about any fuel you can think of.  They’re workhorses.  Properly installed, which we help you make sure of with our harness, these coils almost never fail– they’ve proven to be one of the most reliable parts on my race cars.

This kit includes the IGN1A Smart Coils, Billet Brackets, plug wires, and left and right side wiring harnesses that are as close to PNP as possible– you simply plug them in where the factory harnesses were, and wire ignition switched 12V to power the new relays.

Note:  The brackets will not fit LSA, LS9 engines that have the coils bolted directly to the valve cover without a bracket. Wiring harnesses will not work with LSA, LS9 engines as the ignition coil harness and fuel injection harness are combined and use a different connector.
