Hello, I would like to know if anyone has aftermarket ignition coils installed? New OEM ones are going for about $500+ leading (trailing are longer out there), and i'm looking into an alternative brand and came across MSD; I know i can buy them used for $40-$100. Would i need a standalone ECU to run them? Any difference compared to the stock ones? Thanks!

Little bit of searching goes a long ways.

 

The stock ignition coils are very Beefy as they are.
Why Go "new Oem' when you can get a set Used for about 50 bucks on the Sec gen Parts For Sale section?
Guys are parting out cars everyday.

 

Thanks! I'm concerned about the remaining life of the coils. I don't want to be stranded on the side of the road one day because one of the coils failed. So i'd like to be on the safe side. And I know i can just carry around spare coils just in case. But thanks anyways, the link above answered my question.

 

i read Scrims link but theres no write up for the trailing just the leading. Can you hook up msd on the trailing side or is one on the leading make it unnecessary? heres the write up

No real point in doing the trailing too. Hell if you really wanted to you could take out the trailing coils and not run trailing at all and the car would run fine-ish. Generally they are an upgrade for leading only, add a tad bit of power, sometimes better idle, yadda yadda.


Poster above was right though, as a general rule the stock coils/igniter are really durable. If you wind up stuck on the side of the road it's not going to be because of them :P

 

thanks for clearing that up for me

 

the igniters will fail first way before the coils.

If you want a "stronger" ignition system, best way is to get a CDI box. Most simple install is the hks twin power (can be found for around 250-300), the MSD boxes are cheap, but damn thats a lot of wires...

 

A full ignition setup not just coils is FAR superior to the OEM units.

If you are going to buy MSD coils you must run a MSD box with each unit, like a 6A, 6AL etc...
