I am changing the spark plugs on my ej255 (2008 wrx). On the left side they would be more convenient to be on the surface of Mars. They are under the battery/air pump and the piping to the air pump. I have gotten to them and changed the closer one but the last one is in a tiny crevice. I have a jury rigged system with the actual plug socket and extender then a joint with another extender to actually turn it but it will not turn. It is 100 on the plug and I'm lost. Am I doing it wrong, whats the method?
