Seems legit?

I'm using new OEM revision C coils and the latest OEM wires and would like to keep them as fresh as possible.

 

Seems like a decent, if pricey, piece of aluminum.

Whether or not it would actually have any beneficial impact is anybody's guess.

 

Just drill holes in your stock bracket.

 

Yeah, really, drill & Dremel.
I just realized they were punched out, I didn't look closely at them.
I thought there was some kind of little square insulators.
That's expensive.

 

Either way it does nothing and the white spots on the coils mean nothing.

 

^Yep, fairly common misconception people have about white spots. I thought they mean the coils were burnt up, but apparently, Mazda officially has said that they don't mean anything.

Like said, nobody is sure if give coils a bit more cooling truly helps. I have seen attempts where people would add a layer of insulator between the coils and the bracket.

 

I run one of these: https://rotaryperformance.com/collec...coil-insulator

Came with the ignition kit I got from them.

 

IMO the white spot is usually just deposits that dried there after being wet and then dried by the internal heat multiple times.
