I buy the loud mouth for my bikes because it gives me piece of mind knowing it's a perfect seal, it's also way easier to service the filter and filter skins fit much better and won't fall off. It's a quality product but a little spendy so that's why I gave it 4 stars.
Loudmouth High Performance Air Filter Intake Kit

Give your self a break and your dirt bike a boost of performance with the Loud Mouth High Performance Air Intake Kit.
The Billet Series Loud Mouth Intake Systems are engineered and CNC machined in-house from a solid block of 6061 billet aluminum to maximum tolerances, making this one of the lightest bolt-on performance products in the industry. This new design eliminates the weld of the flange to the intake housing and significantly increases the integrity of the product.
The perfected universal air filter setup eliminates the need for the O.E.M. filter cage and/or backfire screen and creates a higher velocity, obstruction free airflow entering the intake tract.
Most motocross riders will find a power boost in the bottom end with extended top end rev performance. The Loud Mouth intake kit is also known to reduce low-end bog. Maintenance time will be dramatically reduced with the simple installation of the air filter to Loud Mouth mounting bracket that provides a perfect seal to lock out dirt.
- 4.75" diameter inlet significantly increases velocity of airflow entering engine.
- Cooler intake charge.
- Boosted horsepower, torque and instant throttle response.
- Improved airflow allows bike to start easier in fewer kicks.
- Amazing high performance intake sound (within legal dB limits).
- Revolutionary cageless filter design is 100% obstruction free.
- Provides the best seal ever available for the modern motocross bike.
- Clean air box even in the most extreme conditions.
- Quick 30-second filter changes.
- Easy installation, no jetting / mapping required.
- Kit includes: Loud Mouth intake, Racing air filter, hardware, front fender decals, air box decals, installation template, and detailed instructions.
- 100% American made and patent pending.
- Notes: Works with Mototassanari intake boot. O.E.M. hardware will be reused on some fitments.
I bought this for use on a CRF450r for sand riding due to the 100% seal provided by the 360 Degree clamping surface. Now I can be absolutely certain that no sand gets past the filter. Combined with the prefilter for the sand I can run my filter much longer with less worry. Filter changes are now quick and easy, no grease or neoseal required. Installation was fairly simple though I would recommend removing the subframe and air box to make it really easy.
We have Loudmouth's on all our bikes. Cannot testify to Hugh horsepower gains. I can say, that all bikes from full-mod to bone stock get plenty of air. The seal these filters have is unsurpassed, the ease of filter change and having the same filter fit all our bikes is more than worth the cost of the unit. Can be tedious installing. Do yourself a favor and pull the sub- frame ( the young ones won't hear as much cussing )
My KTM simply became ALIVE after loudmouth is install....Don't forget to purchase a few extra of the air filter and the washcap....
ADVISORY : NOT FOR THOSE WHO DON'T LIKE TORQUE ON THEIR BIKE.....
Run these on all my bikes simply for the total seal of the air intake system! best product out there to keep your motor dirt free!
I put one on my '10 CRF450. Installation took a while, but the thing makes filter changes and airbox cleaning sooo easy. Also, I can put this on each of my bikes and then everything uses the same filter. I have five filters, use the no-toil oil, and throw them all in an old wash machine with oxyclean when they're dirty. This is as easy and pain-free as filter maintenance gets, I never hesitate to pop one in between sessions if the track is a little dusty, you're in and out in under a minute.
I think that for the price, the mouthwash cap should come with the filter housing. That's my only gripe.
A MUST HAVE IF YOUR ARE LOOKING FOR THAT EXRA PERFORMANCE FOR YOUR MX BIKE. LOOKS TRICK AND MAKES REMOVING AND CLEANING AIR FILTER A BREEZE.
It seals like non other and is awesome if you ride sand, it keeps everything clean and its easy to throw on an outerwear on and keep everything super clean. It really does seal better than any other, but..
It robs some power and really I didn't figure it out until I rode my friends bike (same bike) back to back with mine. A week later I installed a power flow and it was a boost of power. So to say it boosts performance, I don't think so.
bought this for my 450x... install was harder then thought... i really had to take the plung and hammer the thing into my air box or cut it out... it went in no harm done but at first i was like wtf it wont fit! someone else suggested using silicone... great idea the neopreme gasket is flimsy and install would go easier if it wasn't so flimsy but other then that works great... best mod done to my 450x... i hate the air filter changes and once even ripped my stock filter trying to make sure it was seated.. you will never get anything pasted the loud mouth... that insurance and the ease of air filter changes makes this thing tops in my books... would do it for any bike i own in the future...
I've had loudmouths on all my bikes and I don't regret spending a single penny on them! The seal between the filter and intake keeps dirt out, and filter changes take 20 seconds. Ive noticed a bit more low end as well! Great product I will continue to run loudmouths in all my bikes in the future!!
I got this intake mostly for easy filter changes. It cut my time spent changing filters in half, no more grease or messing around with that wing bolt.
I will say the filter looks a little small, but it moves enough air I'm sure. There's a noticeable sound difference, no real power gain though.
Install was fairly easy, if you know how to remove the rear subframe, you'll be able to install this.
I found it easier to remove the tail end of the exhaust, but I have dual cans so not everyone will have to.
Also, have some RTV silicone on hand! I went to install this and had to run to the store, save yourself the frustration and get some before you start.
install was way tougher than described. I had to grind off some edges to get it to fit. Gasket is sort of floppy which makes lining up the holes very tough. There is not a lot of space to get your hands in to put bolts on and tighten. I took air boot off as well and it was still hard. I ended up using some RTV to hold the gasket against the Loudmouth piece to install. Not sure I noticed an real gains in HP either. Filter changing will be a tad easier but it is not as huge a deal as described by most. I will use No Toil. Not sure it is worth the $$.
Added this to my sons CRF250R and I have to say it does make a difference. I could notice the difference off the line and out of the corners watching from the sidelines. Add the fact that the airfilter changes are easier, and after a year, I have seen near zero evidence if dirt intrusion- unlike the stock setup. Installation was pretty involved, but doable with the right tools, a couple hours and some patience
Install goes easier if you just take the subframe off and the intake out. Once you do that, it's a snap. Noticed immediate gains all around and crisper starts and throttle response. Plus it's easy as cake to change filters.
The system overall does the job. Simple design and easy to install. I did not notice any performance gains. The filter is very easy to remove and install. I did not see one grain of sand inside the intake after 4 different rides with the intake system. If your just looking to keep your motor dirt free and your hands clean on filter changes this is for you.
The intake system is overpriced for sure but it does keep the dirt out. For the money I would expect some fancy packaging to make me feel better about the money I spent but thats not the case. Its packed super cheap.
I know its pricey, but the ease of use and time savings over the life of your bike makes up for it. Had to order this after changing the air filter the first time on my crf which I plan on keeping for a long time. Only 4 stars since I feel this could be sold for a more reasonable price, then everyone would have one.
Noticable horsepower gains on '03 crf450 and made airfilter cleaning much quicker.
This is my second, first was for a crf 450, no I have this one for my yz 250. It is a little spendy that's the only down side.
Before installing this I would notice that every so often a little debris would somehow get past my air filter ( Uni). That has not happen since I got the loudmouth. Didn't notice any increase in engine performance over my uni but that fact that it seals completely is what sells me on this product.
Installation was about as easy as changing a filter. I didn't notice any power increase, but changing filters is so easy and grease free!

With the Husqvarna switch over the manufactures have slowly been going through the process of crossing the P/N's for the Husqvarnas and updating fitment. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
Normally when installing a slip-on only minor changes to the air/fuel ratio are needed, if any at all. But with the addition of the intake, more than likely you will have to reprogram your EFI. I would recommend installing the exhaust and riding the machine to see how it is running then decide if you need an purchase an aftermarket EFI tuner .
