odd. its going to do that if i copy/paste. sorry bout that.
just type in 2003 chrysler 300m thru the search and go to electrical > ignition system > and coil

or: http://www.trademotion.com/partlocat...layCatalogid=0

you will need for the 300m coils:
Connector housing: p/n 90980-11246 (4 required)
8 Connector wires: p/n 82998-12440 (8 required)


i will update post 1.


ive also read that k20 coils are awesome coils. they run about $80/coil though...which can get pricey. CBR's run about 45-50/coil, and 300m's about 30-35

30520-PNA-007 is the K20 coil

i'd say you could get a set of K20A coils in the USA for about $100, there are lots of honda's over there. Check with a wrecker.

Yes.. Good Find..

You need to use a resistor type spark plug on Coil on plug systems.

You need to set them up as wastedspark. so 1/4 and 2/3.

This kit isn't CDI. Won't work on the EVO 4-7 because DSM's use slightly different ignition trigger signals.

Your EVO 1, however, will like it. I used to make these back in the day! Adapting on a CDI will take a bunch of extra wiring but nothing groundbreaking.

Coil on plug

So I have been reading all the COP threads for weeks. I bought a set up for pretty cheap from ebay. The guy was running this on a GSX which now I realize does not run on wasted spark like our Evos do. I am going to take it apart and re-wire it. My question is will I absolutely need to run the CDI box with the 300m coils ( part number UF269)?

and the order our spark plugs are set up are (1-4) + ( 2 - 3) but where will I get the connector that connects the coils to the car it self? The GSX has a different connector all together but still only three wires.

Any suggestions on that?

What I would like to know is the benefit of the COP setup for our cars and at what point the stock system on the 8s and 9s becomes overburdened
