A little harder to install than I thought, but still not bad. Have to completely remove the stock air box and drill out the 4 rivets holding the stock filter inner assembly together... big whoop. Power gain is definitely worth it. Ran with stock exhaust pipe and can still feel a slight difference. Very convenient to get the bracket, filter, and outerwear all in one package.

Great intake system for my raptor 700. Fit perfect and the size of the filter was big. Just the right size to get the lid back on the intake box.. Air intake is much better
My husband bought and installed this on my Honda TRX 700xx. It was easy to install, and dramatically improved the performance on my ride. The throttle lag, which was minimal at the lower RPMs, was completely eliminated and the torque was increased significantly. If you are looking into purchasing an air flow system, I highly recommend this one!
Took about 35 mins to put on easy to install with the right equipment would recomend could tell a boost in power alsome product.
Very easy to install. Well worth the money. Gained a nicer torque curve out of it. 2003 banshee.
Item does not say that u may have to jet your carb until you read the directions that come with it . . .I would of thought that this would of been clearly stated on the item details. Also, I wish it would of went more in depth about how much you have to modify your stock air box For these reasons, I only gave this item a 3 star rating
just bught this kit for my 08 YFZ450, the install wast that bad at all, removed the air box and made the swap, the only down side, if you wanna even call it that, is that now i need to jet my carb, already had a GYTR slip on and after the intake ive lost alot of my bottom end throttle response, it back fires and spits flames while deccelerating, other than that the difference in power and torque is easy to see
For the amount of work it requires to put this on, just leave your filter lid off. For the airbox to come off you need to pull the muffler on a LTR. I have a yoshi full system one peice setup and its a PITA to pull off for a air filter install. I will be returning this filter kit.
product works great but to install on my 2008 honda trx450 you must modify your airbox by trimming and cutting the back of the box. The filter is to long and hits the mount tab for the stock filter. K&N should make the filter shorter by just half inch. Quad runs great after though. should rejett carb after install.
Installed on my KFX 400. Took about an hour. Had to pull seat and remove airbox completely to drill the bolt holes. Make sure to get a good seal with the O-ring. Comes with an Outerwear. Inexpensive way to boost your quads performance.
This took about 40 min to install, on the raptor 700. It works great, and a noticeable gain in power. Make sure you have a fuel programmer, PCIII or such. I run the fuel maps for the pro design kits, and it seems to work just fine.
Just installed it on my '05 yfz450 and its a nice product. I like that its clean compared to the traditional oily foam filter and not to mention the added power you get from more air flow.
this air filter takes out the bachfire screen so you go from a 3 intch hole to a 5 intch hole
Hey, this is Jebba again. I was deeply impressed with this product. It performed for my needs. I saw that it gained 7 horsepower on the dyno and 1000 rpm's. Love Jebba
Very easy to install and made a noticable change in power.
On a 07 raptor 350 it was very easy to install but I did have to grind down the top part of the air box to fit back on all together it took about 40 minutes
A must have kit it added some more power and its easy to install
I found the provided (2) drilled and tapped holes in the adapter right over the molded corners of the stock Warrior air box, so the bolthead and nuts have no flat surface to secure to.
The fix was having to drill and tap an entirely new hole on one side. And on the other I had to drill out the threads, allowing the bolt to pass through the adapter freely in the opposite direction, then fabricating a uniquely shaped nut to fit in the molded corner of the air box. Along with some Loctite, that secured the other side.
Once this was done I had the K & N airflow and protection that is a must for any ATV.
Great product. Easy to install. Makes a big difference over the stock filter. Would highly recommend.
This kit is what any and all quads need. Max air flow for better performance. Great sound that stands out from the rest.
