plugs

[ripp444]

further to my previous thread i have fitted the single electrode plugs that euro sold me (the ones i took out were twin) the car does not seem to pull as well now.
is it my imagination ?

Probably...

[Josh_Quant]

what brand are they?

So long as the plug is of the correct nose length and hear rating it will be fine

GTis should just use standard NGK plugs. They don't get on well with these fancy twin or quad electrode plugs.

the ones i replaced and the new ones are ngk

I use Bosch super plus spark plugs,to me the engine is a lot more responsive and have never had any issues with using these

That's the placebo effect of replacing old knackerd plugs

Many years ago I had a race tuned mg metro, had a set of plugs that at the time were the thing to have , split fire plugs had the car on the rollers and the car was miss firing under load.
The rr operator knew his stuff on the a series so we went through changing the carb spring rating, oil in the carb damper changed the needle but although they improved things they didn't eliminate the issue , as a last resort we swapped the plugs out for my old used NGKR. Plugs I had in the car, miss fire went and the car made a few bhp more.
Swapped in a new set of the same plugs and he had to alter a few settings and got a few bhp out of it!!

Stick with standard plugs, with multi electrode you still only get the one spark
