Warning, the following post contains both grilled and fried spam, if you or a loved one is allergic to spam please refrain from proceeding any further. Thank you.

Disclaimers aside, quite a few people have asked about these and I finally have them available at 3dpmoto.com

There are other options out there for these, but I quickly realized that none of them are very affordable for the average guy who doesn’t need a $300+ carbon piece. This is a budget friendly option that will get you the same benefits, but comes in well under $100. Here are a few key features:

- Available in blue or black

- Made from OEM components to ensure a perfect fit, no aftermarket plastic parts are used

- Comes with all necessary seals and hardware, no tools are needed for installation

-Fits 2018+ YZ450F and 2019+ YZ250F

- Scoop is 3D printed from a semi-rigid material (to protect those "vital" areas in the event of a cased jump)

- The printed in roost screen can be easily cut away if more airflow is desired.

Thank you for listening to my TED talk, if there’s anything else you’d like to know just ask away! Also, huge thanks to the various members who have expressed interest in these, I’m sorry it took so long to make them happen but I’m really happy with how these came out Cool

You've earned the right to cook a little Spam in here...

Looks legit, good for you, I hope you sell so many you have to work day and night to keep up with orders!

Why do they need ? Already making the most HP and intake noise in both classes

Nice work. Looking at the location on the bike in order to make this a true ram air or cowl induction you need to make another 3DP insert for the front number plate to allow air to flow between the forks and straight into your plastic intake. Right now the front number plate is deflecting a ton of air, especially at speed. Not sure if someone already makes a vented from number plate for the yamaha but if not that should be your next product. Should be pretty easy to make:

I’ve had that thought too, I might home make one but I’m surprised there’s not something mass produced already.

The intake looks rad though! I like that it’s an oem base so everything lines up and seals just as the stock one does. Well designed.

I'll take one. Need it for snow biking. last year the pow was so deep we had to plug the intake shrouds and use those little UNI inserts on the cover, This is a better option.

This benefit the 21 250F as well? I recall reading something about the 21 was slightly redesigned for better airflow.

MX bikes do not go fast enough to get any "ram air effect" this lid does what its suppose to do and that is to get more flow into the airbox but no forced induction because of the low speeds.

Yes they will, plenty more air from forced induction if the number plate is vented. At speed I said, not putting around or sitting on the gate obviously. All you need to do is tape a streamer to the side of the front number plate and you'll see there's plenty of air moving.

NO,NO not even at speed on a motocross track! on mx bikes all air going through the engine is drawn in by the engine itself. For any kind of ram air induction you would have to be going well over 150 mph and then its minimal even if with your holes in the number plate. Who tells you this stuff ?

Amazon has you covered for $19.99 you can mount these up front and cut holes in your number plate and you will get every holeshot. ,

I’d say there’s a lot of people using them already and don’t need a vented front plate. I’m no engineer. I would think you still need the filtration pre air filter somewhat.

Hahahaha, that's cute. 150mph huh? Very cute. Did you seal off your radiator shrouds and mount the radiators on the rear fender because there's not enough air flow for those either?

Garbage mate. 150 mph🤔🤣🤡

Positive feed and cold air intakes start working at low speeds if the airflow to the filter is insufficient or negative. Ram air as in supercharging does require high speeds.

At 60mph you’d be looking at roughly .07 psi increase in intake pressure.. Basically nothing compared to atmospheric pressure of 14.7 at sea level. So yeah the “ram air” benefits from venting your number plate or creating a scoop for your other scoop is not going to be beneficial.

It would be beneficial for sure. Go look at how much you can gain just by changing out the air filter on the YzF...now imagine air being forced into the airbox from guided airflow from the vented number plate straight into the intake. More cold air will result in more power.

It's not forced induction. It's not even forced induction on an aftermarket truck intake (that goes much faster than a dirt bike).

Nice parts Josh!

Thanks all, I really appreciate the kind words and support! It's been a bit of a process to get these production ready since this is just a side business for me, but I'm really happy to be able to offer an option for these bikes at a reasonable cost. I tried to make these as minimally invasive to the rider and as aesthetically pleasing as possible.

I should mention, for an additional fee you can add your name and number to the scoop for a fully custom setup. All of these just feature the 3DP logo since I had them in stock, but a custom scoop can easily be made to order. You'll see the option to select whether you want the standard logo or your name and number on the product page.

As far as the ram air debate goes, this was never intended to provide a ram air style function, only to add some ventilation to the airbox in a way that's a little more elegant then drill holes in the airbox cover. It's possible that you might get a little bit of benefit in that way, but I'd be stepping out of line making claims regarding increased performance since applications and conditions can vary so greatly.

I can't make any claims about dyno numbers, but if you look at any of the MXGP or Star bikes they all have some additional airbox venting. We're from the same area, so if you'd like to see one in person to get a sense for how much more air it will allow in I'm sure we can meet at one of the local tracks.

Positive feed and cold air intakes start working at low speeds if the airflow to the filter is insufficient or negative. Ram air as in supercharging does require high speeds.
Forced induction is a turbo or super charger, ram air induction is by speed and only works at hi speeds, don't tell me you don't know the difference between forced air induction and ram air induction Pinch You don't need high speed for a turbo or super charging to work because you are making your own atmosphere and force feeding the intake, you can have full boost on a turbo without the car even moving and just by how high you are revving the engine. You have everything bassackwards its also about 230mph for air ram induction to work.

Ram air induction does not exist in normal vehicles for all intents and purposes. Ram air induction is the forced induction of flow due to air flow being compressed (pressurized) into an inlet from the conversion of kinetic energy (velocity). Air is considered incompressible below speeds of about Mach 0.3 or 230 mph.

A supercharger and turbocharger both perform the same function--to force air into the cylinder above ambient air pressure. More air + more fuel = more power. The difference is that the supercharger is mechanically driven, while the turbocharger harnesses waste energy of the exhaust stream.

Contrary to what your intuition might indicate, having a forward facing air inlet to "scoop" air into the engine does not produce any significant pressurization of the inlet air below Mach 0.3.

Therefore, the difference is that one is very effective at increasing power (superchargers/turbochargers) and the other is more effective at draining your wallet (aka snake oil).

That is increasing air flow and air box volume , not because its ram air. Go spend a day at the drag strip and tell them your silly idea or better yet the Bonneville salt flats. You will get laughed out of both places.

Its not you, you know what your product does and it does it well, its this clowns like Black Diesel bomber who has zero clue how these bikes work and how the engine breaths and there is no ram air effect at low MX speeds. Blush

You must have gone to MMI because I have not seen anyone so clueless when it comes to how things work. You could build all the duct work and vents you want on a MX bike but it will never have a ram air effect, now move more air to cool the bike through oil coolers or radiator's but a MX bike will never have even close to the speeds to get a ram air effect. The engine will pull in all the air it needs and but it wont help to run ducts or vents to try to ram air into the airbox. Pinch And venting and ducts is not forced air, a turbo is forced air and so is a supercharger but your goofy idea wont make any difference is what is called ram air and its a catch phrase for suckers like you in the automotive industry to try to sell cold air intakes and hood systems.

You are simply trying to back track with a play on words acting as if I said to mount a turbo or supercharge to the number plate (cute amazon fan). If I thought your farm was worth anything I would bet mine against yours that guided air from the front into the scoop would increase power at speed whether it be from ducts or guided air through forms in the front number plate. Not sure how much power, but definitely a power increase due to the ram air effect.

I guess VRP Mugen did all this very difficult fabrication work nothing:
