9 months later all good with the black DMCoils. I am calling them black because now they offer the red ones too, those improved ones. I paired them with NGK Spark Plugs SITR7A11G (94949). Those were notoriously hard to source and had to wait for months to get 12 but eventually I got them for nothing vs OEM platinum plugs.

I sourced my plugs from ML Performance by the way. But Opieoils had them too, just only 8, not 12 in stock. lol

 

Good to know. I hope their version of the newer, square-headed coils are just as good, because Aston service center says those are the ones I need for my Vanquish. Apparently MY2015 was the year they switched to the newer ones in the AM29 cars. The current part number for them is ED23-12A366-AE.

 

The good thing about the square coils is there's lots of brand name (NGK, Hitachi, Denso) as well as Ford Motorcraft, that will be cheaper and better quality than even DMCoils.

I went with MSD Coils myself in my coil change thread for the AM29 on my car:

If you google Coils for Ecoboost 2.0 , you'll also get a lot of spiced up aftermarket brands like Granatelli
