Spark plugs tight
The spark plugs on my 1.8 1998 petrol engine (AFT) seem to become tighter with time, despite being torqued correctly and having their threads cleaned. The plugs are VW/Audi 4-terminal types. When I first got the Passat I decided to remove the plugs and see how they were - and they were dramatically tight and remained that way for most of the unscrewing process. I torqued them in and a couple of days ago decided to check / clean them if required as some time had passed - they were tight again and hard to remove. Cleaned / re-torqued again to 20NM - as recommended. Any ideas?
