We have specifically tested several aftermarket air filters/flame arrestors on 496 engines and I can tell you with certainty that the stock Mercury flame arrestor with its internal bell mouth opening flows the most air effectively for this engine. There was no improvement with the other aftermarket units and in a couple of cases there was a slight loss of flow. If you boat in a dusty or dirtier enviroment, then the K&N would be a good choice for dirt control because it filters better than the wire mesh factory flame arrestor. If your engine area is clean then save your money and use it for better purchases.
