Finally got the plugs out!!

[cняis]

looks like you had BKUR6ET's in there before

NGK recommend either BCP7ET (KR engine) or BKUR7ET (PL engine?) either way the 7 relates to a higher temp spark plug. Both are triple electrode just like your originals.

GOLF MK2 (84-->91) 1.8   KR / 16 VALVE   85 –> 91   BCP7ET   
GOLF MK2 (84-->91) 1.8   PL / 16 VALVE   10/85 –> 10/91   BKUR7ET

WHORE!

whats wrong with singel electrode plugs ?    they work better   trippels are just an old way of extending plug life

Single electrode plugs, shroud the spark, and give a far less efficient burn. Triple electrode plugs give a far more exposed, larger, longer lasting spark, that is allowed to penetrate more efficiently into the fuel mixture, upside, easier starting, improved economy, longer lasting, never need gap setting, and more BHP... downside, they cost more!

Sorry but your just quoting manufacturer marketing garbage there. Find me a high powered race engine that uses mutliple electrode plugs? Single electrodes shroud the flame front far less than mutliple electrode plugs, allow you to make fractionally more torque/power due to this (which incidentally means you increase the fuel efficiency assuming all else is equal) and result in fewer carbon/crap deposits which can premote knock. The strength of the spark is purely related to resistance/supply current and by that the spark gap so there is no difference in reality and where that statement of penetrating more efficeintly into the mixture came from who knows but yes, mutliple electrode plugs last longer since the gap can be maintained for longer and might save you a few pennies if your the sort of person who is happy leaving a set of spark plugs in an engine over the course of mutliple services rather than being sensible and pulling them at each service which will maintain your fuel economy and engine output much better than multi electrode items. If you do see multi electrode items specified, its purely down to manufacturers extending service life
Be carefull of marketing blurb and bum dyno's, they are very rarely accurate.

Funny you should say that, because ALL of our race cars use the multi electrode plugs,
I'll get on the phone to all the engine builders and put them right...

who cares ??

[SoundillusioN]

Lets not get started on these ones then!

[clipperjay]

Single or triple or quad it depends on the amount of heat you need to get better combustion no point in stick real hot plugs if the head can't handle hard detonation.
Why do I know this because I've mucked about so much with plugs, you really don't want to know and cant be bothered to explain

they look cool will they give my valver more horses
