The Yamaha jetting instructions state to run their recomended jetting with the filter cover off.

I did that and ended up with a airboz full of sand untill I found this, The EHS Air Box Cover.

Thanks to Meiko the Cat holding BoxCover in place
Note the filter is framed in quality billet aluminum as is the cover over the snorkle hole. The genuine Outerwear filter is correctly edged and installed smartly.
Choice of colors, and you can get the kit to build it yourself with your own airbox cover, or they'll send it to you complete.

Our 2 EHS covers arrived in excellent condition, remarkable quality

eh.....just get a real intake with a an outerwear and you wont have to worry about that anyway.

looks cool though

 

[Mustache Ride]

how much was it btw?

I went to their web site and I didn't see the YFZ450 on there yet, so I'm guessing you have to call to get that one. Those are awesome looking by the way. The Z400 ones were $80 for them to do it or the kit was $47, but with the extra metal for the YFZ, I'm guessing they'll be a little more expensive?

I did do that and don't like the idea of a airbox filter housing full of gooey sand.

Several times I cleaned it out with a spoon solvent and towles and I don't like the idea of sand coating the gooey filter/outerwear.

This lid you simply wash off. The filter and box below isnt covered with gooey sand and is much easier to clean.

This method far superior to what you mention.

I just ordered my complete lid for $94 bux shipped priority from Eric. He coudnt be a nicer guy and told me to call him anytime if i had any questions.
Call him here and order EHS RACING 607-847-8765

That is nice I guess but I have not had a problem with my ESR intake with K&N and outerwear. And I don't even have an airbox much less a lid.

And I ride in the sand almost every weekend.

 

[seatec]

Yeah but for some of us in the wet & wild north east with lotsa mud & muck it might be a different story.

True, but I thought he was tallking about riding in the sand?

 

[seatec]

[liftedtaco38s]

Yes that is correct.

It would be a good idea to run those outerwear panels on both sides of the airbox as well. I would be concerned with that small surface area getting covered with mud and water (trail aplication)

 

[Asher]

does anyone know where to get the outerwears material in like a roll? what do you guys think of a airbox made out of the material, in other words like a nice sturdy frame and each side has a peice of outerwear? maybe the whol ebottom covered up? any ideas?

 

[LapTraffic]

That was pretty much what I was getting at. More surface area to let air in.

Hey, I think I saw in "goldenwestcycle" that outerwears does make a airbox cover. ITs the same material as the filter outerwears, but kind if sounds like a "shower cap" Idea. It was only like $18. I'll call goldenwest, and see if they have them for the yfz.
Those lids do seem pretty nice though. I have never been one to liek running open lid. THough, I have since I have owned the yfz, cause there was such a big difference. I think I will be getting one of these lids, if outerwears doesnt have one of there little deals for the yfz

After looking into farther, I have decided to go with the EHS kit. I ride in real dusty conditions in the summer, and really wet conditions in the winter. I dont think I'll loose any performance by adding this lid. I just feel that its not safe to run NO airbox lid at all.
I have already found way to much dirty snow in my airbox, from running with no lid, however, running the K&N, with prodesign, and no lid, I have never got anything to flow past the filter. I ALWAYS am checking the intake boot, just to make sure!

Just oredered mine. I was looking at the pics that he sent me and it looks like he kept the stock snorkel duct on there. I would recomend sawing that bad boy off, as that will make the airbox bigger in volume, and more air can be inside. Just my opinion though, thats what I am going to do.
