I have a 1986 1.9 WBX DH T25, i was wondering if somone could confirm the size of socket needed to remove the spark plugs. Also am i right in thinking 0.7mm is the right gap to set them at? Thanks

the gap sounds about right

sockets can be cheap enough
for 1/2" drive

Thanks for your reply, so they are 14mm? I had read they are typically 21mm? Glad i asked this question now! Thanks again!

i don't know how it works, the sockets are 21mm or 14mm, i guess there are different ways of measuring the same socket

Oh i see, so a 21mm socket and a 14mm socket still will remove the same spark plug? Maybe one is depth and one is diameter or something. Sorted!

The spark plug is a 14mm dia thread. which is why they are called 14mm spark plugs the actual size of the socket is 21mm
