I believe quite a few folks have, yes. Work fine, but I don't think they offer anything more than a longer lifetime over the standard plugs on the whole.

I've used Denso Iridium IK20 plugs, they helped a bit when I had some running issues, which turned out to be 6 bent exhaust valves.

After running-in post engine rebuild I switched back to standard plugs to see if it made any difference, and it was not much, a little better pull top end with the IK20's.

I think the BKR5EIX may have a fatter centre electrode aimed more at long life rather than performance.

I have ngk iridium... Not shure if thats the number but its for vr6.... Noticed no difference at all from the oem plugs....

And you won't. Spark plugs are another Snake oil product. The cheapest of the cheap NGK BKR5Es work fine in the VR6. I buy plugs in bulk from America at $2 a pop....

ok just to confirm then; ngk's website recommend bkr5eku for the vr6 - twin electrode

but this forum most users often talk about the ngk bkr5e - which is only single electrode

and by using the search and going through some old posts which lead me to some links on where to by these plugs from, another varient was recommended which is ngk bkr5e II (which i do not understand what the significant diference here is to the bkr5e)

...can someone please give the definitive answer and please explain the rationale behind it

 

 

from what i can deduce it seems as though the twin electrode (ngk bkr5eku) is the plug of choice. That then lead me straight to another dilemma ...plug gapping.

After many hours of reading i came across this interesting thread:

it basically concludes the plug is pre-gaped and measuring the gap distances requires a slightly unconventional method
