Review on 🔍 FRAM Extra Guard Air Filter Replacement CA8768: Advanced Engine Protection & Optimal Performance for Select Mercedes-Benz Vehicles by Tony Beale

The listing says they work in my 2007 Mercedes Benz c230 Sport and although they do fit, within a drive cycle or two they named, the engine gives 3 error codes. The codes indicated a faulty mass air flow sensor and 2 faulty O2 sensors. This shouldn't be the case on an engine under 70,000 miles so I checked all the sensors were good, cleared the codes and waited to see if it happened again. Again this happened within a few ride cycles so I replaced them with Mann filters (c3698/3-2) also bought from Revain and have had no problems since (2 months). Fram appears to be much less durable and is made from thinner and inferior materials. I've never had a problem with Fram in domestic cars in the past, but I won't be using them in my MB in the future.
