Does anyone know wheres a good internet site to buy a K&N (AIR) FILTER for a 06 Raptor 350? Also how much difference does the filter make? K&N claims filter will add HP?

 

Try rockymountainatv.com It doesn't really make a big difference till you put a exhaust on cause if you breath better you can't fully take advantage of it until you can exhale better.

 

If you change the filter you need to rejet the carb. To make any noticeable power you need at least the pipe, filter, and jet kit. You won't notice any HP improvement with just the filter. K&N does add HP, but only maybe .5 - 1 HP. partsunlimited.com has whatever you want, magicracing.com, ronniesmailorder.com.................

 

Alright thanks just added the filter,need the jetkit now.

 

You need to jet it as soon as possible if you already installed the filter so that your engine doesn't run lean and do some damage to your rings and cylinder.
