Re: K&N Air Filters
Frankly, the K&N filters rely on what amounts to 30 year old technology and heavy marketing. All of the systems on our bikes and cars have improved yet we reach for this inferior product based on this marketing and the impression that this is all that's available. These filters are based on a porous cotton gauze which, by itself, filters almost nothing and can cause serious dust ingestion (damage) to your engine. Then they recommend that a customer applies this nasty cleaner/oil ( Disodium Metasilicate) to the filter before and during use. Why do you suppose they require this oil? The fact is, once the particulates begin to stick to this oil, the restriction level and flow decrease is very dramatic. So much so that it normally performs worse than the original filter. Either leave the existing filter in the car and replace it regularly or buy a new technology, high performance filter like the Amsoil or the even better flowing and filtering R2C Performance unit. These are a little more money but they are cleaned with low pressure, compressed air and NEVER need DM oil. By the way, read the warning label for the process before you start applying this stuff. Remember, a filter should be a filter first and when designed properly, not subject a user to the compromises we face with existing cotton/oil products. Happy motoring.
