Big difference in power with powerlid on, not only greatly increases air flow but also adds another filter. Glue on velcro wore away quickly and in extreme heat lid warped but was easy to straigten back out, just set out in the heat again on flat surface.

If you want maximum air flow with great protection this is the filter for you. I put one on my 07 kx 250f and it fits great. Another good thing is you don't need to clean this filter as often as a foam filter.

Increases airflow. Nice product for the price. Thumb screw did no fit in 08 CRF150R, used stock screw, stock was better anyway.

Good for a back up. Mine started coming apart at the seams after a few washes.

I was skeptical or dropping $$ on a screw. I could care less about the looks of this particular part as no one will ever see it! But I absolutely despise my CRF250X when I have to put the air filter back in - sometimes taking up to 5 minutes!! When i openened up the twin air package and compared the bolt to the OEM one, it really isn't much longer and I was pretty skeptical. However, when I went to install the air filter it was amazing how easy it lined right up!!! I've done 4 or 5 filter changes with this bolt now and every single time the bolt magically goes right to it's hole and I'm done in 15 seconds!!! You won't regret this purchase.

Shipping was fast as always with Rockymountain. The air filter works great but came apart at the seams faster than the twin air after many washings.
