bloody hell that is the price for a single spark plug for my scooby

ngkpfr6b super platinum from halfords £13.99 each

my 8 valve has twin has done since i brought it

no 8valves have single electrodes

I think twin electrode ones are standard on an sri, they are on the 16v's.

i got the 4 prong ones semmed better but they were due for replacement
gonna get ngk next
champion seemed ok in my fiat?

Some give a stronger spark than others and some last longer and can perform better at very high temp.
Champion plugs are shit never buy them.

the other ones charge a fortune saying that they give u more power etc, when its just a load of crap :)

how can spark plugs be 'better' than others?

i thought the only purpose of a spark plug was to simply make a spark!

what makes ngk or vauxhalls better than others?

on the subject of spark plugs mine are twin electrode is that standard for an Sri? does anyone know?

Were your NGK's fairly new though? As someone said above, they were maybe due for replacement.

Well i had NGK's in there and when i put in the bosch 1s the car definatley seems smoother

ngk are the best value imo

they all do same job at the end of the day!

I have these i wouldn't buy them again waste of £ imo

ur better off using ngk v grooved or standard vauxhall ones

I dont reccomend these in anyway, if you noticed the improvement then your old ones must have been faulty and you would have felt the same improvements with new original ones.

i had those in my corsa B i didn't feel any difference so just using standard ones in the C

Don't think they ave really improved the car alot but it definatley feels smoother not bad for 15.99 i think really good value surprised i noticed ne difference really just changin the spark plugs
