I have a handbook for a 1953 Anglia. The old Ford sidevalves didn't change much over the years, so the Champion L10 listed in it will most likely be the right ones.

Champion L10, as exbmc says, used to have them in my E83Ws.

Welcome to the forum btw, any chance of a thread about your Anglia?

I have had so many problems with Champion in both the bike, and the Moggy, I do not give them shelf space. Stick to the NGK for me.

Totally agree with that point.

Also agree. The NGK equivalent of L10 is B6HS.

When I had my old Plymouth I put a set of NGK plugs in it and it would never start when it was hot. I went back to Champions, problem solved!

Sounds as though they were the wrong grade. On the other side of the coin, I recently changed the NGKs in the Morris after well over twenty years, motivated solely by a guilty conscience, not because they were dud.

I have no connection with them but try the Green Spark Plug Company. I had trouble with a very old Rolls and after contacting them I changed the plugs to a non specified plug recommended by them. No more problems. It would seem that the slower burn rate of unleaded fuel affects the combustion and a different temperature plug was required. Hope this helps.

My understanding is that the flame front of modern fuels travels much faster. The burn is also much hotter and drier than was the case with leaded fuels. These characteristics are probably due to the use of 'aromatic' additives (principally benzine and toluene) to restore the octane rating in the absence of lead.

By the way, this 'orrible stuff is also highly carcinogenic, so keep well away from the fumes when refuelling.
