What's the big deal about ordering proper BP5EFS plugs online for a few dollars each? :confused: Just get 12-18 so you have some spares.

I have had my 300sel to ~114mph on a stock ignition system with the proper plugs, so I don't understand the purpose of replacing all the bits as shown.

To each their own.

gotta love i6, changed plugs+ wires in an hour!

Both supposedly No No for M103

only place cld find bp5s on a UK website, sparkplugs.com doesnt even have them

new wires are non resistor so R plugs r fine

why are platinum plugs bad? idt the car knows if copper or platinum or iriidium is lighting it up

1. You don't know how to shop, they're easy to find.

2. Doesn't have proper resistance like that, I checked into it.

3. Factory called for copper, non-resistor. Anything else is wrong.

500 SEC coil change
 
I have a 1984 500 SEC can I use a MSD coil and does my stock coil have a resister, in other words do I have to worry about ruining my car with a Accel coil or MSD?

jha2297255 09-16-2008 08:59 PM

the blaster ss coil is .3 ohm , if you dont have a current limiting ign ( i think , and other ppl on here have said the stock 300e is) msd suggests an inline resistor

dont hold ur breath emailing msd tech, i still never got an answer from a month ago

worth noting, my tach works fine w MSD coil

PS mSD coils made in china, if i knew that i wldve prob gone w jacobs or something US made ...

Your tach would work fine because the speed signal, also called TD, is from the EZL ignition controller. It goes several places, the fuel pump relay, the idel speed controller, and the CIS ECU, among others.
