Re: Volant CAI
The donaldson powercore filters started showing up in the diesel truck world a few years ago. Major advantages were flow levels did not degrade as the filter got loaded with dirt, and the design could trap and hold significantly more dirt than conventional pleated designs. They are oem on the ford powerstroke and scorpion diesels now, and have something like a 60k change interval. Good technology, not reuseable though, you will have to buy a new one eventually.
