rickwood Posted March 26, 2010 The airbox on my '02 is cracking, so it's time to replace it. I could just buy a new '02 airbox. The price for a new '02 airbox is $111.99 vs. an airbox for the '03-'04 for just $55.87. Since it's time for a new air filter too, I can buy that for either year just as easily. If I buy, the '03-'04 airbox, I assume I will also need the new cage ($32.70) and bolt ($5.09) too. Hence, the price ends up being within $10 for either option. If I understand correctly, the '03-'04 is a bit bigger, making it slightly harder to change the filter. Are there any other pros/cons of going one way over the other? I am not certain if my current set up has the fix for the infamous '02 airbox leaking problem or not. As I ride mostly sand, a good seal is pretty important to me; hence I'm leaning toward the '03-'04 airbox. I've also thought that I might use an '05 air boot. I've heard that the air flows better through it, thus giving a bit more power. If I do this, will it mate up properly with the airbox and carb, or will I need some additional parts? Also, is it likely that such a swap will require changes to my jetting? Share this post Link to post Share on other sites
HrcRacing Posted March 26, 2010 The box on my '02 was terrible. Definitely, made for ease of assembly not sealing. In '03, they went to a steel airbox filter base and a double-lip boot. The '02, as you know, has a single lip boot that just mounts flush to the airbox. If it were me, I'd go with the '03 airbox. In '04, they went back to the plastic crap although I do believe, if my memory is correct, it had a double-lip boot. I would think that no jetting changes would be necessary for an airbox switch.
