Decided to treat my Type 4 to new plugs and leads and all was going well until I tried to put the new plug in cylinder 2. No matter how hard I try that plug will not go in. The hole in the right cylinder cover does not line up with plug hole and I can't manage to align the plug so that it threads. I'm sure I can't be the only one that's had a problem with this plug. Is there a trick to getting this plug in?
I use an Audi HT lead to start the threading in process on 2 and 4. The end holds the plug lovely. But check your old spark plug hasn't come out with a helicoil on it. That may explain another reason why it's not biting. You'll see the thread on the old plug is much wider if it had.
