I searched, but maybe not well enough. I have a 98 C230, do they come pre-gapped? Thanks guys

Thanks nenad. on this page it shows a gap of 1.1. But when you select the model, it shows a gap of .032. I was just making sure I am good to go.

does the 4cyl require 2 plugs for each cylinder like the sixs and 8s?

the usual 20ft/lb for gasket type and 10ft/lb for tappered type plugs.
