Racing spark plugs different length for classic impreza turbo?
Have just bought some racing type spark plugs for my classic impreza turbo but compared to the pfr7b plugs the overall length of threads/tip is shorter. Will this effect anything?
See attached pictures.

They look ok to me, If your worried grab a feeler guage and check the gap The threaded section only looks longer on your new plug as the old plugs washer is crushed
