Hahah i know, the idea just made me giggle.
I meant i didn't notice it running any rougher than it did normally, ie it was no different with the plugs than without. This was back in the day though tbf - before i had any mechanical knowledge or sympathy - so maybe it was a bit worse and i just didn't notice.
Let us know if you do, be interested to see the effect. With regards to mpg, personally i think the coolant pre-heater is more likely to make a difference, mine is knackered and it takes forever to get the engine up to temp and i have correspondingly crap mpg. Tell you what, you try the plugs and i'll try the pre-heater, we'll see which has more impact.
Anyway, we're getting off-topic, the poor op's not going to know what's hit him/her.
