Hello fellow 'Yota Nuts. This is my first post on here. I have a '21 200 series with the 5.7 that I am wanting to add an air cleaner to. I currently have the factory airbox with an ARB Safari snorkel. I found a company called Donaldson that makes air cleaners for 200 series that have the diesel engine. Does anyone know of a company that makes a good quality air cleaner for the 5.7? Thanks!
