Ok, I love my 03 400i 4x4 auto, but, i'm starting to wonder if its a retarted size or something. I am looking for aftermarket add ons to gain a little more power and loose a little weight off this thing, i'm coming up with exhausts and filters and stuff on multiple websites, too bad it's all for 500's or 300's, they just don't cary stuff for the 400's WHAT GIVES!?!??!

 

I noticed the same thing Its hard to find anything for a 400.

 

Hard to find?? I think its pretty much impossible

 

I did find a K&N filter on the Dennis Kirk site. I think they will have a jet kit soon. I bought a clutch kit from EPI I will put it on in the next couple of days.

 

I look forward to hearing if any of these mods you will do will make any differance to the performance or power of the quad. What web sites have you had the best luck with finding the clutch kits and K&N filters??
