Spark plugs for 313/318 small block engine

[Nick Challacombe]

Please could anyone inform me what is the current equivalent of the "Autolite" A32 spark club specified by Bristol in the workshop manual. I keep going round in circles but can find nothing definite.
Champion mention RN14YC and RN11YC
Autolite 65 and 64's also 751s
NGK are mention but non seem to be suitable for a 313/318.

Thanking you in anticipation, Nick Challacombe

Not what I required thank you

Thank you Peter, simple google,

I too tried that but fail to understand why 21 plugs from 9 different manufacturers were the equivalent to Bristol Autolite 32

I was looking for a recommendation, not a clue as to which search engine I should use.

Thank you all the same.

I went on same roundabout as you and ended up with these - NGK BP6S.
SLJ who had serviced the car previously had used NGK BP5S's.
Am happy with the plugs - mine's a 410 with a 318.
Hope this is of some help.

I covered many miles in 2 different 410s as daily drives using BP6RS. The same as Andrew suggests, but resistive. Originally using standard ignition, then with Lumenition electronic. No problems with them and would fit them again.

I think I missed out an R and mine are resisted as well - will go and have a look in a mo.

For my sins I bought NGK AP8FS stk 2227 , which will be fitted next week preparing for a tour of the Dale’s. We did Brecon and the Gower last week and I felt the old girl should have all fluids changed and the filters, plugs, and pads including the hand brake pads which after 22 years of ownership and the fact the handle is now vertical need attention. The power steering fitted two years ago is a god send. I have done 60k miles in the beast , the only problem this year has been the Facet Red top fuel pump which occasionally ceases to function after stopping on a up run, but a tap on the body gets it going. I have cleaned the filter but have bought a spare just in case.
Thank you all for your help , including Peter the simple Googler !

Glad you've got yourself sorted - sounds like a great couple of trips.
