I'm sure most of you already know but incace some don't.
After having oil leaking up the side of the terminal recently on my 2004 gs I got a replacement from a motor factors for a third of the price.
A Bosch part,as in photo.
I’d given up replacing them on my 1150, only seem to last a few thousand miles. If they can be sourced at a reasonable price then I might start replacing them again.
