Club 80-90 Forums

The only thing left to complete the service is spark plugs.
I have purchased 4 x Bosch super four WR78, which after entering my Reg on the website, said they were compatible with my bus.
Could anyone advise if these will be ok to fit as cannot find anything on the forum that mentions this type.

I guess ID numbers change, I liked the W7DTC triple electrode but they are not easy to find.
Remember to gap the new plug at 0.7 for petrol 0.6 for lpg

This is a very good cross reference

where did you buy them ?

In the end I got them from Euro car parts as they had a 30% off online.
GSF also have them listed for my vehicle reg.

WR78 are OK but a bit OTT for our engines where cheaper standard WR7DC plugs will also work fine.

You don't gap multi electrode plugs.

Thanks for the helpful replies.
Will crack on with it later this week.
Appreciate they are OTT for the age but for the price why not!

You don't gap multi electrode plugs.

Or use them for LPG.
My apologies there's not a reference to a single electrode plug in my post for gaps
Thanks.
