Here is a picture of my filter on the truck. The only markings on it is the word "front" embossed on the solid area. If I were to drive in a particularly dusty area I would replace this with an oil bath air filter for sure. The only thing it is good for is to eliminate rocks and birds.
Our Grand Master may note the carb (Carter W-1) which was purchased from him several years ago and it continues to do it's duty.
