AEM IGBT Inductive Ignition Coil
AEM "dum" ignition coil The type of ignition coil you use on the build when you already have the ignition module or distributor installed. (also found in some aftermarket ECU) The coil gives up to 103mJ and at least 40000 Volt, which is in class with most CDI systems. This is the first type of "dumb" inductive ignition coil that provides a CDI-like spark with long spark duration necessary for overcharging.
AEMs High Output Dumb Inductive Coil is designed to be used with an external igniter.
AEM?s High Output ?Dumb? Inductive Coil is designed to be used with an external igniter.
AEM?s High-Output ?Dumb? Inductive Coils each deliver up to 118mJ of spark energy and a minimum of 41,000 Volts?as much as most CDI systems, without the need for a CDI module! They also provide very long spark duration at full energy, unlike CDI systems and multiple spark systems which fire off small spark events prior to and after its CDI burst to mimic longer spark duration. The full energy delivery and long duration of AEM?s High-Output Inductive Coils eliminate the need to compromise energy or duration with your ignition system, and will increase performance in high-boost or high compression engines.
AEM?s High-Output ?Dumb? Inductive Coils deliver CDI-like spark energy with the long duration of an inductive coil, and easily install in place of your exiting coils without the need to add a CDI. AEM?s coils are constructed to operate in harsh environments. They are shock and weatherproof, allowing them to be mounted virtually anywhere. They are affordable?less than the cost of aftermarket LS1 coils?and deliver World Class performance. ?These coils are on 2,000-horsepower nitrous motors without a CDI, and they perform flawlessly. We think they are in a class by themselves?, stated John Romero, AEM Director of Product Development.

Who you are buying from
You are buying from a drift team, not a warehouse.
Our founder competes himself in his own drift E46. Our team build and race the same platforms you drive and work on, and our sponsored drivers chase championships on the same parts we sell worldwide.
01
We have already broken it for you.
Our founder, a full team of sponsored drivers, and hundreds of other drivers worldwide are out competing on this stuff in drift and rally. When we tell you a part is good, the part is good. It has already been put to the test.

“After trying a few better known brands such as Tilton and Extreme, and never being super happy... Conor was able to recommend me the perfect clutch for my application... I havn't broken any drivetrain parts since I installed it.”

Tell us the car. We will spec it.
Chassis codes, spring rates, angle kit clearances, clutch ratings. Send us the car and what you want it to do. The answer comes from someone who has run that setup, not someone reading a product sheet.

Ordered before 1pm, fitted this weekend.
In-stock parts ordered before 1pm are dispatched the same day. UK and Ireland typically arrive next morning, worldwide as quick as three days. Times do vary, but that can mean the part is on the car within a few days and she is back out blasting the roads by the weekend.

Straight answers
The questions you were about to open a chat about.
How do I know it will fit my car?
Send us your chassis code or your reg in the chat and we will confirm before you spend anything. If you order and it turns out to be the wrong part, we swap it.
“Had a mix up with the item description (order wrong part) they was quick to email me and see what part I was meant to order and substituted it for no extra cost!”
Bradley Page, verified customer, 31 Jan 2025
When will it actually arrive?
In stock and ordered before 1pm, it leaves the same day. UK and Ireland is usually next day, occasionally 1 to 3 days. Europe 1 to 5 days, rest of world 3 to 5 days on express.
If something is not in stock, we will email you right away with an ETA and any available substitutes. On the rare occasion it does not work out, we will happily refund your order.
Will I get stung for customs or import VAT?
No. The price you pay on our website is what it will cost to be delivered to your door. You will not receive any surprise surcharges after ordering.
What if I change my mind?
30 days on all stock items, full refund on the parts. If you ordered the wrong thing we will help you get to the right one for as little money as possible. We have been there.
What warranty do I get?
Everything on our website is covered by the standard manufacturer's warranty.
If you ever need to claim, we fight your corner. We will do everything in our power to make sure you are looked after, rather than leaving you to argue with a manufacturer on your own.
Can I pay it off over a few months?
Yes. Klarna and Shop Pay Finance are both at checkout, so you can spread it without putting the build on hold.
Can I just ask someone what to buy?
That is the bit we are actually good at. We run our own race team and workshop, so you are talking to someone who has fitted it, broken it, and fitted it again. Hit the chat and tell us what the car is doing and what you want it to do.
