Best Spark plugs to use on 1992 Cabby K-Jet

As above, Too many peeps saying which ones are best

What do you recommend

Thanks

I have been running with NGK but to be honest my mates garage serviced my cabby and did brakes etc 3 months ago and i have to admit its running just the same as it did before and i haven't looked what type of plugs hes fitted. i try to get plugs with the at least 3 side electrodes this tends to give a better spark as they don't cover the center electrode as old type conventional plug do, but as far as i can see as long as you buy a well known Brand ie Bosh Champion NGK etc you shouldn't go far wrong.
it would be wise to buy better high quality plug and ht leads.
