So, I finally converted my '84 to DLIDFIS today. Wow, what a difference! Need to deal with a freakishly low idle now, but otherwise it's nothing but good. Anyways, I'm still running 4 OEM 1st gen NGK's. What does everyone else run for leading/trailing? I searched and found talk of 2nd gen plugs, but nothing too specific. I see there are a lot of choices out there! So, what is everyone running on their DLIDFIS?

 

Stock NGKs for now but I'm thinking of the next plug swap going to the RX8 plugs. I hear they
have better performance. Check it all out in this thread.

And yes I did comment in that thread in 2008 but my setup has changed and I think the Rx8 plugs
are the logical next plug for me.

 

Fc plugs are free or pocket items at boneyards lol

 

Holy ****, that's a long thread! Just when I was about to run out and get some 2G plugs, I get turned upside down, haha...those RX-8 plugs sound good, but not at $20 a pop!

Still looking for more feedback. A lot of info in that thread is about stock ignition. Are stories of 2G plugs cracking housings true?

This.

Stock ngk's are the right type to run with those coils, if you go 2nd gen coils then run 2nd gen plugs.

I'm actually running Accel Super Stock leading coils, if that makes a difference.

 

When I went DLIDFIS(using more stock diamond coils and stock ignitors) in my SE, I kept stock plugs for trailing since it still runs through dist., and use 2nd gen(BUR7...???) for leading since it's now direct fire. That's what was recommended to me, and they have worked great for a few years now, and they look good (color, carbon build-up), too.
