K&N High Flow Replacement Air Filters (Yamaha YZF R6 2004)
Shop for Motorcycle Air Filters

     For those looking to increase the power of their motorcycle, replacing the stock air filter is usually a good place to start. Many people say that aftermarket air filters give you the best bang for your buck in terms of power gains. It is also a very simple modification that does not require much technical knowledge or skill with a wrench. Coupled with an aftermarket exhaust and more aggressive carburetor jets, an aftermarket motorcycle air filter will be especially effective.

     Going back to the basics, increasing horsepower means increasing the amount of oxygen and fuel getting to the engine. Aftermarket motorcycle air filters are designed to allow air to pass through with less restriction while still protecting the engine from contaminants that could damage internal engine parts. Most stock filters are made of paper and are disposable. The filter is pleated to increase the surface area through which the air can pass. The paper is good at filtering out even very small particles but it can restrict air flow significantly.

     Probably the most popular aftermarket air filter is made by K&N. They offer quality filters that boost performance while still meeting emissions requirements and protecting the engine. They are probably less aggressive than some filters but they find a good medium for someone who is looking for something between an all out race bike and a bone stock ride. These filters still have the same pleated design to maximize surface area but K&N filters are made out of cotton sandwiched between two layers of thin mesh. A tacky oil coats the cotton of the filter element to trap any particles before they can reach the engine. Though K&N air filters cost quite a bit more than OEM paper filters, they can be cleaned and re-oiled with a special renewing kit. Many even come with a million mile warranty so you may even save money in the long run since the filter itself will not have to be replaced. There are a ton of knock-offs out there but I personally would rather pay a little more and purchase a trusted name like K&N than trust my engine to a nameless brand.

     In cars, the whole air box can be replaced with a high flowing tube but most aftermarket motorcycle air filters are direct OEM replacements. This means to install it, you just have to open up the air box, remove the old filter and pop the new one in (Consult your owners manual if you need assistance with that). This power mod is really too simple to even be considered a true modification but it definitely is a good place to start adding power to your motorcycle.
