About this part

The catalytic converter on your R 18 B K35 converts the pollutants in the exhaust and decides whether the emissions test passes. Rattling when pulling away, a loss of power from blocked ceramic or a lambda control fault all call for replacement.

Frequently asked questions

What should I check when buying a catalytic converter for the BMW R 18 B?

Emissions standard, engine code and flange dimensions of your R 18 B K35 matter, because a converter for the wrong standard never brings the sensors into their control range. Look for a valid approval number on the housing and check that the lambda sensor bosses and heat shield are there.

A used original converter or an aftermarket one?

A used original fits without surprises and keeps the vehicle's approval, but tap it first to hear whether the ceramic has come loose. Aftermarket converters cost less yet need the matching approval, otherwise the roadworthiness test turns into a problem.
