How many of you are using the K&N Power kits,do you like them and do you feel that they are worth the money.I ride with mostly 450's and in most cases my machine compares evenly I feel to them eg. top speed and in trails,but some times in the mud it would be nice to have a little extra power-would this kit help?

 

I have one and it give alot more power i got it just because it came with a filter and needle jets and a buch of jets that i needed to tune my pipe,
