SL600 Stock Air Filter housing porting
I put BMC filters in my SL600 this week, when I took off the air intake(filter) housing off I noticed the stock housing has significant protrusions into the intake path, mostly where the housing is mated to both sides , I ported the intrusions and also opened up the turbo to intercooler cast aluminum tube straightening the airs path....not a lot of time required but I thought what the hell while its off, cant hurt.
