Probably a stock oil bath then. No heat to it.
On my old truck I just do the heat soak method when I want to drive it. I run it on high idle for 5 minutes. Shut it off. Give it 5 more minutes then fire it back up. The heat from the motor radiates up and warms up the intake. But even then it sometimes wants to fart around when I drive it. I just keep the rpm's up a bit till it's fully warmed up. I'm running an open element air cleaner so no heated air.
