Where is the oil filter on 2008 tundra 5.7 4 wheel drive?

If you are asking about the 5.7L engine.................

It's under the skid plate. But I suggest you talk to a service manager at Toyota first before you attempt the oil change yourself. (IT'S NOT THE SAME AS YOU HAVE DONE IN THE PAST.) You may also want to ask the service manager where the transmission dip stick is located. Be ready for a shock when you find out.
