    Made a difference - Honda TRX400X

    I am looking to get the most power I can out of my Hinda TRX400X without compromising the reliability of the machine. This was easy to install and it seems to have made a difference in the performance of the machine. It sounds a bit deeper without being loud. I would definitely recommend this as an easy mod. Others are correct it is not inexpensive, but it is does more for performance than other filters. I did not change the jetting even though the jets are included. Local Honda dealer did not want to change the jets. You don't have to, but I can tell it would be an even bigger performance gain with the included jets installed. I backed down from a 5 to a 4 rating as there are slights blemishes in the construction although they do not hurt construction or performance and K&N should come up with a better way to attach the DryCharger cover and the stock airbox clips were very difficult to close with the powerlid installed. The cost is not an issue if these small details were resolved.
