I have a 1989 mini 30, and the engine is out of the car for some maintenence just now. Whilst it's out I was going to replace the spark plugs.

 

Just wondering the code of spark plug I should use and the what the gaps should be set to. The old spark plugs have the code BP6E (brand NGK), not sure if this is correct though.

 

It is a 998cc engine.

 

cheers

thats great, cheers. is it ok that the car has been running on these BP6E plugs? didnt seem to bother it.

 

whats the gaps?

[cal844]

To be honest i dont know i never check the gaps, i just make sure the gaps look the same and fire them in.. If the car runs ok, i advise using the same plugs

Hope this helps

cheers, looked in the manual and the gaps are there thanks

No problem, id suggest you change the rotor arm, cap , leads

(so they are new and clean)

Just been done, only have done 30 miles on them, just the spark plugs needing done

Thats perfect!

I use BPR7ES, this is a 'colder' plug to prevent hot spots with my high compression engine.

If you have electronic ignition then you should use the "R" plugs, eg BPRn* and when using points BPn*

 

For standard engines the '6' plugs should be fine, but you may want to use the '5' plugs on lower compression engines and 850's, 7's and 8's should only be used if you start getting electrodes burning out on higher performance engine. Using a plug which is too cold can be even worse than using one which is too hot.

Whats the difference between these 2 ( BPRn and BPn)?

R is restive plugs the other is not

[Dusky]

^But what is the advantage of that? Would it cause any abnormalities when using non restive plugs?
