GTi spark plug question

[blake12345]

Hey, sorry this may have been something that has already been answered somewhere and I have looked but can't find an exact answer

I've got some bkr7eix plugs that I was going to put in my 2013 polo GTi but they seem to have a shorter thread then the stock ones that were in there...

Are these plugs ok to use or are they the wrong ones??

Thanks
Blake
