Works

Fits tight! After 1 inch hole drilled out. Crisper throttle response.

They seem to work

I installed four of these on my 2003 RM 250. The bike runs better and the motor seems to be able to breath better. This gives it a crisper throttle response and it rev's easier. It's not a huge difference but you can notice it.

Serves its purpose, barely!

They increase flow to the throttle body but are cheaply made the foam cones right out of them.

Just a little extra air to boost the top end!

Work as described. Installation was a snap. Literally. Looks OEM.

Great product!

Don't waste your money on a k and n powerlid these vent are great you can remove the foam filter in the vent and clean them when needed And they provide more air versus the stock lid. But that is a no brainer. I defintely recommend this product!

BOX VENTS

I was a little hesitant to start drilling holes in my air box to get more out of my DRZ-400s, but with these It felt safer. They aren't to fancy but look as if they will get the job done. Plus i just put on a power bomb header, power core 4, and re-jetted, boy does she fly!

Would these be okay for dusty conditions?

These allows more air to pass into the airbox. Keep in mind these are little vents with pieces of foam to help keep some dust and dirt out. if you're riding in extremely dusty conditions, your filter will become dirty quicker.

yes, you can put oil fliter in the foam too.

About how many of these will u use on your bike?

The package contains 6 vents. I've seen people use three on each side of the airbox. The amount of vents you would like is entirely up to you.

as many as you want, the more, the better.

Will water or dirt get into the box?

Yes, putting holes in your airbox does increase the risk of sucking something through, but these do have screens to filter out the larger stuff that's sucked through, so you shouldn't really have anything to worry about.

water will get in the box the same way if you didnt have these installed, but you can oil the foam to stop dirt getting in.

Do you need to rejet for this?

Most likely not but it depends on the other mods you got. It wouldn't hurt to double check it though.

Not to sure on the exact dimensions of those vents. You can always contact Uni directly for the exact specs.
