Can anyone give me the correct O Ring size for the intercooler/intake manifold seal on a 98 E300? Mine is leaking boost pressure and I need to replace it, but it is my daily driver and I can't remove it to measure it, shy of doing the job twice.

Thanks ahead of time for any guidance.

I believe its easiest to get it from MB. This forum has an awesome shop with staff that know benz's properly
