I have a Mazda 6 2011 model, I wanted to replace spark plugs but I have got a problem with the 4th cylinder others (1-3) have no problem. As I attached pics it looks like the 4th plug socket size is completely different.
Anyone has seen it before or any idea how to remove it.
I am currently working on an engine swap to replace the cooked L3 in my 2005 GG2. However, the Motor I've bought is a Series One and I've had nothing but issues.
Currently, she's at the point where the original coils for the car are hooked up but I don't seem to be getting spark to...
