2010+ Mercedes OM642 Intake Manifold Swirl Valve Removal and Port Match


2010+ Mercedes OM642 Intake Manifold Swirl Valve removal. This is for all OM642 Engines that have the BlueTec Urea Systems. This is a service we offer for the intake manifolds. We will clean the manifolds and remove all the EGR and CCV oil build up. Then remove the swirl valves and weld up the ports. We can also port match the intake manifold ports with the cylinder head. The intake ports are slightly smaller than the cylinder head ports. This will reduce pumping losses and create less turbo spool delay and increase HP on engine with more aggressive tunes or turbos. Intake manifolds need to be sent in ahead of time to perform modifications. We can preform other services upon request. You need to send in your intake manifolds for service work. See contact info for shipping location. Typical turn around is 5-7 days, longer for full port.
