Spark Plugs

Howdy peoples,

I was just reading through my workshop manual, when I noticed that EB-ED XR6's use different spark plugs to the standard EA-ED 6's.

Does anyone know what the difference is???

Would there be any performance gains in my EA (MPI, Cam, Head work, etc.) if I ran these spark plugs?


Cheers,
Dave

Hi Dave

All i know is they run a different compression ratio.

XR6 is higher.

Might have somthing to do with it?

Cheers
Kerry

Hmmmm, if that's the only reason, then it might make a bit of a difference to my baby, since her compression should be slightly higher than that of an xr6.


Thanks, mate.


Dave

The XR6 ones have a different temperature range. They run great in standard 6's and even better in LPG cars.

Kewl, thanks for the help, guys.

I'll be putting a set of those in on Wednesday, I'll let you all know how she goes.



Cheers,

The XR6 / LPG spec plugs are a different heat range AND the electrode height is slightly different (probably at least in part to do with the heat range - ie. height of the insulator). I thought they were cooler, but I'm fairly sure that the insulators end up being taller which contradicts that.

I have consistently found them to make my car feel noticeably sluggish (have tried them 3 times in 5 years - most recently last week - thought it worth trying them with the Dev 5 cam).
