C3 AIR INTAKE KIT YAMAHA YZ450F 2010+
CAIN1722
Your dirt bike’s factory airbox system was designed for hot, dry, dusty air. When riding in snow, your air filter will get wet and freeze, causing a rich fuel mixture, hindering performance and risking engine damage by overfuelling. Enhance your bike's performance, with improved throttle response with a less restrictive cold-air intake system that is water resistant and light weight. The #1 choice for a no-nonsense, tried-and-true, reliably powder-proof snowbike intake solution.
One of the most vital additions to any snowbike! (Along with a thermostat)
NEW: KTM / Husky / GASGAS owners should also check out the new Airbox Delete Bracket!
Relocate the side panel mount so you can easily disassemble and remove the entire front, bottom, and back of the inner airbox for optimal snow evacuation
No more cutting plastics (no other bike brands required airbox cutting to begin with!)
Machined aluminum for a precise fit
NEW: where needed, a custom-built breather filter is included! This comes with a number of advantages:
Functionally, very similar to our original intake system. The main difference is that, in the event there is any oily sludge buildup or a tipover, it is not reentering the engine via the intake
Simpler and cleaner install on 2019-up KTM/Husky and other models
Now compatible with 2021-up Hondas
Filter is compact, with high-quality filtration element and a robust aluminum & rubber body
Its purpose is to stop snow/ice/dirt/mud from collecting and plugging your breather tube (which could result in pressure buildup and major oil leaks through the valve cover seal), while ensuring your valvetrain can still vent any positive pressure
Attach it to the end of the PCV vent breather tube (a rubber line usually coming off the top of your head at/near the valve cover) with the provided clamp, and secure (typically to the frame) with the zip tie. Make sure it is the lowest point of the line, as any vented oil-water mixture can't be allowed to accumulate as it may still freeze. Make sure the filter is not in direct snow spray (you can cut the breather line if you need to. the filter is beneficial to run all year round).
This replaces the old strategy for crankcase ventilation of direct connection to the air boot. The only real "con" is that it's a different paradigm than dirtbikers may be used to.
UPDATED: we're using custom purpose-designed and optimized air boots instead of off-the-shelf adapters! Better fit and improved airflow!
This intake system mounts right up where your stock airbox was, with a laser cut aluminum pod, mounts for your PCV system and air temperature sensor, all necessary mounting hardware, and a custom dual-layer Outerwear prefilter, made in the USA by “Outerwear”
