Paul,

I just received the RX8 coil from Advanced Auto Parts.I did not believe
that I was going to receive them since I read that a lot of people tried
to purchase them online but were told that this item can not be ordered
online.I went to Advanced Auto Parts web site and ordered 4 coils.I was
surprised that the order went through without a problem.However,I
thought that I will never receive them instead I will get an email of
apology for a web site error.But to my surprise I received them today
and they are the right coils.The box states Intermotor part #E1001.The
funny thing is that I live in a US territory in the Pacific called
Saipan and Advance Auto Parts has to ship them thousands of miles away
from the mainland US.By the way the cost was $24.00 per coil and $12.14
for priority mail shipping for 4 coils.What a deal.

Someone needs to tell the people that answer the Advanced Auto Parts
web site phone :) I have an RX8 coil heat sink for you. I'll
come up with a place to mount it in the firewall forward package.

Actually somebody has to tell the people that maintain the web site at
Advance Auto Parts,cause I understood from the emails that I read that
most of the problems they encountered were ordering through the web
site.At any rate if you want the coils I be glad to order them for you.

Hi Michael,

I would like to order some coils, if that?s OK.

Did you notice that they have triggers as well.

Cheers Chris in NZ

 Chris,

 I am not really sure if it has a trigger or not the only thing I noticed
 is that it has 3 terminal input plug.Have you tried to order them
 directly from Advance Auto web site lately.Things might have changed
 since before.If you still can not order them,I will be glad to do it for
 you.The cost as I looked lately was $26.99 per coil.The shipping to me
 is about $14.00.I do not know how much will be the shipping to NZ,but I
 will inquire if you still want them.I also do not know if you have to
 pay tax in NZ or not but that will be something that you have to deal
 with at your end.Cheers.

 Michael

 The trigger is built in. It requires a positive going  5 volt low current
 pulse that is only 3 ms long to work at high RPM. If you want it for
 aircraft use you should use a heat sink as they are not designed for a
 continuous 6000 RPM.

Hi Paul

What do the Star Mazda cars use for the coils.
Are they stock like the rest of the engine,
and do they have experience of coils dying?

Steve Izett

The 1st gen used a distributor and maybe MSD.
I am not sure of the brand of coil.

The 2nd gen uses RX8 engines so my guess is RX8 coils.
If they did I am sure they switched to the new version
about 2006 to 2007. A race car spends some time
braking so the RPM is not always 8500 RPM.
Here is a histogram of a Le manns lap.
The Le Manns course has one of the longest straits
in the world. I know the 3 rotors in the Rolex
series uses heat sinks on the coils.

Thanks Paul
So at Le Mann the engine runs below 6K for approx 7% of the time.
I wonder what it would be for the Mazda's, perhaps similar?

Steve Izett

The Star Mazda cars run on much shorter tracks so they spend
a higher percentage below 6000 RPM.
