Durability 5/5 Ease of Installation 5/5 Performance 5/5 Style 5/5

This product is very good u got to get if u have a after market Exhaust and ur quad is jetted I have a ltz 400 and it made a world of difference You could just take your airbox cover off and not spend a 129& but I think it is well worth it a very good well-made product I would recommend it to anybody

Great , Keeps everything out of airbox.

Been running this for two years now and am very pleased. With the powerlid gause filter and inner foam(stock) filter you can bet no dirt gets by. I believe the instructions tell you to run a inner K&N but I chose to keep the stock foam. Works great , with a nice bump in power over stock. My velcro is still stuck good. You have to clean , sand, clean where the velcro goes and it should last.

Just take the lid off and buy a k&n filter with prefilter. A hundred bucks saved...

alittel pricey but worth it. i got a good power gain with lid & filter. ya gotta jet it with all that air comein in. i got a 08 ltz400. the lid came with a 150 & a 160 jet. i used the 160. i recently added a pipe & jet kit. the combo was awsom.

Amazing power gains after a jet-kit and pipe. And after all its a K&N!!!

I bought my 05 Raptor 660r without a air box lid. It had a K&N filter. The problem was I couldn't get in any water for obvious reasons and when I would pull a wheelie all of the power would be loss. This lid fixed it all. Comes with a filter for the crank case breather hose and the dry charger cover that goes over the lid. A great buy!

Alot of power

this power lid adds alot of power to my ltz400! sends about twice as much air to the engine its very easy to install takes about 2 minutes includung putting the adhesive strips and mud cover on...definately have to put jets and exhaust on when adding this upgrade

Decent add on.

The power lid really adds to the performance of my quad, I don't like running without an air box cover, and really helps filter out the dirt but I am somewhat disappointed in it's construction. The velcro adhesive didn't stick very good and I have had to replace it and the lid itself has warped from the summer heat so the fit is no longer as tight as it should be.

I have a 2012 Honda 450ER with a full DASA classic pipe and dynojet kit installed. do i need to re-jet for the airbox cover or can i keep the jets the same???

A: That will depend on what you have currently been running. If you have been running the stock airbox lid with no modification, you will probably have to richen it up a little with this installed. It can also vary based on how well the bike is jetted right now with current jetting. If it is on the rich side with stock airbox lid, you might be able to get away with just installing this, although if it is on the lean side as is, it will require jetting changes more than likely.
Q: I have an 06 yfz 450 with a full alba exhaust big gun rev box and k&n air fitler what size jet should i use

A: Since jetting specs depend on where you are located as well i can not make any sort of recommendations for you. Your best bet would be to call a local shop and tell them what you have done to your bike and they can make some recommendations as to what you jetting should be.
Q: Does this filter need to be oiled or is it a dry filter

A: K&N couldn't furnish us a list of which quads include a jetting kit. They said if it requires a jet kit it will be in the box, that's it.
Q: ??????

Q: Does this keep water out?

Q: ?

Does this come with the K&N filter too, or just the lid? Thanks
MotoSport Staff Expert
Over 10 years ago
A: This is a filter of sorts. But if you are referring to the main air filter, than no. This will not include that filter.
Q: Do I still need to use a prefilter on my K&N filter with this lid on?

A: I would recommend to still use the pre filter. It's another barrier to keep unwanted particles out of the motor.
