K&N Buell Firebolt/Lightning/Ulysses Replacement Air Filter - BU-9003

Fits flush all the way around, no gap at the top edge like the last aftermarket one I tried

Full enclosure held up through a week of rain camping, no leaks anywhere, seams are sealed well

Does the job well, just wish the mounting instructions had better diagrams

Optically clear, zero waviness looking through it even at highway speeds. Seals up tight, no whistling

These doors are night and day compared to stock plastic. My kids stopped complaining about mud getting in

Cuts dust down a good bit, still get some coming through around the back window seam on real dusty days

Works but the fan is louder than I'd like on the high setting

Install video on youtube made this a 45 min job. Fit is tight, no wind noise at highway speed either

Took longer to figure out the install than I expected, directions could be better but it works

This is the AJK bumper Trailworx pointed me to when the EMP one I wanted was backordered, glad they did, quality is great

Easy clamp-on install, no tools needed, and they fold in nice when trailering

Ordered this after my stock bumper got wrecked, fit was spot on and paint matches close enough you can't tell
