2007 - 2008 Jeep and Mercedes OM642 Intake Manifold Swirl Valve removal. This is a exchange 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 larger tunes or turbos. We will charge an $800 core charge if you will not be sending in your intake manifolds ahead of time. We request all cores to be returned within 60 days of receiving intake manifolds. Any cores received after 60 days will be charged a penalty of 10% for every 7 days overdue. These intakes are hard to get and are very expensive new. We will refund the core charge once we have received the intake manifolds and they are in reusable shape. We can preform other services upon request.
