  • Fitment
  • This system easily installs into O.E.M. air box - No modification necessary!
  • The all new Loud Mouth Intake System is a game changer. Loudmouth rebuilt the front of the air box and eliminated several points of weakness associated with the O.E.M. setup. They designed the intake to seal at both the intake boot and at the air filter with a rubber seal, which eliminates the possibility of dirt entering your engine.
  • The intake system gathers up air from low flowing areas within the air box and essentially rams it into the intake tract like a velocity stack. Loud Mouth off-centered the air inlet to straighten airflow entering the intake boot to boost performance output to the point that it completely changes the sound of the bike at every RPM. In addition to improved power output, the intake system is definitely not O.E.M. and the billet machined surface incorporates style and simplistic functionality into the air box like never before.
  • Filter changes are safer and can be performed in under 30 seconds unlike 10+ minutes with the O.E.M. thumb screw setup.
  • Installation is a breeze. You do not have to remove the intake boot from the throttle body or modify the air box.
  • Loudmouth recommends setting these kits up with the No Toil Oversized Air Filter.
  • Kit Includes: Loud Mouth Intake, Mounting Bracket, Sensor Screws, Filter, Decals and Installation Guide. O.E.M. hardware will be reused.
  • Mapping not required.
  • 100% American Made and Patent Pending.

Love the Loudmouth!

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.

Installed on a 2013 KX450F

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.

2007 450x

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...

BIKES SHOULD COME STOCK WITH THESE!

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!!

Very cool

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.

Loudmouth on 2008 CRF250X

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 $$.

Great performance boost and more

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

Will this fit my bike?
I have a 2014 Husqvarna TC250. The bike is the same as a KTM 250SX of the same year, except with a different subframe. It is irritating trying to order aftermarket parts for it because it seems like nothing that fits other bikes will fit this bike according to the website, but it often does in real life. So what about this? I only ask because, like aforementioned, they have different subframes and assumingly, different airboxes to cope. I'd very much like to get my filter to seal better without having to use grease around the edges every filter change. It's an awful air filter system, and I'd like to use this instead.

Yes it would fit the 2014 Husqvarna TC250 as well. 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.

No, the K&N filter is for the stock Honda setup with the thumb screw and will not work with the Loud Mouth systems. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

Is this kit or the twin air kit better for a 2014 crf450r? Also have had it reprogrammed when i put the Yoshimura exhaust will i have to reprogram ag?

Both kits are designed to eliminate the back fire screen to increase the air flow. 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 .

Air4orce system & Loudmouth plate?
09 CRF450R - Are there any performance advantages to gain using the Loudmouth Intake in conjunction with the MotoT Air4orce system?
Top 1 Contributor

MotoSportExpert
The internal combustion engine is very simply put a basic air pump. The more air/fuel you can pass through the intake and exhaust from the motor, the more power you will make. HP gains are very subjective to gauge on any one or combination of performance parts. Things like the age of the motor, the tune of the air fuel ratio, the altitude, etc will all have an effect on PEAK HP numbers. Many performance products will not increase your PEAK HP, but rather move the HP to a different RPM range than the stock motor.

No, on a stock bike Re-tuning is not necessary. We haven't had any issues with FI bikes rejecting the Loudmouth intake.

THE LOUD MOUTH KIT COMES WITH EVERYTHING NEEDED TO INSTALL. YOU REMOVE OLD AIRFILTER MOUNTING HARDWARE AND BACK FIRE SCREEN ( WONT NEED THEM ANYMORE). THE NEW FILTER MOUNTING PLATE COMES WITH NUTS AND BOLTS NEEDED TO FULLY INSTALL. AFTER PLATE IS INSTALLED OIL AND MOUNT FILTER WITH SUPPLIED CLAMP. TAKES ABOUT 1 HR. HARDEST THING WAS FIGURING HOW TO REMOVE OLD FILTER CAGE MOUNTING, AFTER THAT IT WAS A BREEZE. ENJOY.

You remove the entire OEM air filter mounting bracket and replace it with this. No backfire screen.

You will remove the stock (OEM) air filter holder plate and replace it with the Loudmouth mounting bracket. The Loudmouth High Performance Air Filter Intake Kit will come with an installation guide and will eliminate the use of your backfire screen.
