HALLO  FROM GREECE!!!!!!!!!!!!

Today I finally got a chance to hit the dyno room again. On the stand a 2010 VMax that just finished it's initial break-in. Safe to hit it hard on the dyno.

We brought several K&N filters to the test to see if there are any gains to be made just from swapping filters. In our recent filter writeup we discussed several options from K&N that fit the new VMax more or less perfect. 

Several hours later and an entire tank and then some used for testing we gathered well over 100 runs with tons of data about the filters and various airbox modifications. With and without restrictor, with and without rear top cover, stock filter, three different K&N filter - all on an otherwise stock 2010 VMax.

Finally found some time to compile the article about K&N filter options for the 2010/2009 VMax. The choices are great, the CM-9908 is my absolute favorite. True K&N - not a blue Made-In-China knockoff. 

If you have to keep the stock airbox (mainly for noise reasons) this filter should be for you. You can find them all over eBay and the Internet.

Power gains with all drop in filter options are limited, but in return you keep the stock airbox.
