Has anyone got any spark plug preferences? It may be my imagination (I don't think it is) but my car (4.0 EB manual) definitely runs worse on NGK's. It idles roughly and has a
harsher top end. It also sounds harsher. On Champions it idles much better and feels considerably smoother, but a bit less grunty. Is this possible???

Both my Fairlanes ( a MPEFI 6 and a V8) have always run best on NGKs. Indeed I have found NGK are best for all the cars I have had.

I have an 88 EA MPFI.
I use to run Champions, but changed to NGK R and found they were much better. Car runs smoother right throughout the rev range.

Anyone had any experience with the split fires?

I have heard that they are

crap the money you pay for them you may as well piss into the wind. I am running NGKR on my XR8 EBII and have had no problems what so ever. I have never heard of people having problems with the NGK's. It might have been a gap thing with your plugs,as they don't have the same gap as your standard plugs.

Using NGK R's and no complaints at all.

i personally like champion plugs, never had a drama with them, other than that, NGK it is for me.

I've run my EB XR81 on champion gold's before. They were good but a it too expensive, $3.50+ a plug but I've gone back to NGK R's and I dont think I'll look back. They felt the same as champions, were just as reliable, and better value. What I dont really recommend is split fires or bosch 4's. Waste of cash IMO

I run NGK R's on all my taxi's (EL - AU II). I usually get around 120 000 - 160 000 Km out of them, unless the leads decide to shit them selfs first. They are good in my opinion and have not had any trouble with them.
