Hey guys,

I've got a s5 FC running the AP Engineering Power-FC and its running with the oem ignition/coils setup.

I'd like to know if anyone else is using aftermarket ignition setups with theirs??

im thinking of going with this setup:

Crane Hi-6 CDI Modules, LX92 Coils, Bosch Coils, with 10mm Custom Leads

here's some links:

I've been running HK$ twin power on the stock FC coils. It's just a small box and a few wires, and it amplifies the leading and trailing

 

i was wondering if anyone has tried the new AEM High Inductive Output Coils. It's suppose to be really strong and even cheaper then twin power. I haven't read anyone that has installed it yet.

 

It's probably a rebadged or copied GM/Delphi part...

 

The AEM coils are the Mercury Marine IGN (no ignitor) and IGN-1A (built-in ignitor) coils. They are HOT. Output is around 100-115mJ @ 2.5ms charge time and up to 250mJ at 6ms charge time. For perspective, the MSD 6A boxes are around 105-120mJ and the "street" M&W boxes are 115mJ. We've constant dwelled the coil at 4.5ms on rotary applications with great success. You will not be able to run them constantly at 6ms. With the PFC it is possible to throttle the dwell versus RPM though to give a hotter spark when you're asking for it.

We were recommending customers purchase the Mercury coils from another shop over the parts we had available through our distributors long before AEM began rebadging them and they became available to us at a decent price through AEM.

In short, the new inductive coils are as hot as most street appropriate CDI boxes. They're spark duration is much longer (better starting, idle, and low-speed performance). They're usually less expensive. Are less complicated to install in most instances. And do not give off the high amounts of electrical noise that CDI boxes are known for.

 

Just as a reference

The cheapest and most efficient way to get a better spark without the hassle of CDI is

4 Mercury Marine IGN-1A Internal Ignited coils / rebranded AEM

& that's it.. didn't realise it was that simple

going to pair them up with magnecore 10mm leads!

 

i'm not knowledgable regarding how the ignition works, but how are these compared to the HKS Twin Power. Only reason i wanted to go that route is becaues it's super easy to install.
