The Twin Air Air Filter's design, high-quality materials and superior construction deliver unbeatable performance and protection - and make Twin Air Filters the hands-down choice of more World and National Champions than all other filters combined.

  • Twin Air filters are designed to increase airflow while ensuring the highest level of protection from dirt / dust.
  • Coarse open-pore foam catches airborne dirt, grime and sand.
  • Fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage.
  • Exclusively formulated adhesive ensures glue seams will not break down.
  • Thick, flat foam, greaseless sealing ring ensures maximum contact with your airbox, while acting as a breathable gasket for increased air passage.
  • Fused outer and inner elements prevent dirt and grime from being lodged between layers, unlike Twin Air, this can be a problem with inferior two-piece designs. Trapped particles can restrict airflow. And, if dirt works it's way into your engine, a pinhead-sized granule will gouge your cylinder, piston and rings like a bullet.

Good filter

Not much to say here. I replaced the old filter on my bike and a friend said get the twin air so I did. It's easy to install and haven't had it long enough to comment on durability and I'm not a good enough of a rider to tell if it helps performance.

No the Twin Air Air Filter would not come with the filter cage. You would need to use the stock cage.

No, the filter comes just as you see the picture, without the cage. But you do get a cool decal with every purchase.

Ordered Air Filter for 2010CRF450R, but there's a Rectangular opening at the bottom of the BOX, I need the sponge that covers that, How can i get it?
the Air Box has a Rectangular opening at the bottom, right where the Tire is, and where i wash A lot. There was some type of sponge filter over that Rectangular opening and it fell apart when Washing it. What was this cover? and How do I order another one? I just ordered the TWIN AIR Filter. but thats just the cover for the intake, The hole in the bottom has no cover now,,,,

From the factory the Honda CRF450R there is not a foam at the bottom of the airbox. That most likely has been added from a previous owner or dealership. They airbox is designed to drain out the bottom. To replace it, you could cut up an old air filter or get some skid plate foam if you want to replace what you have.

I would look for this piece of foam the OEM or just buy a bulk package of foam and cut a piece to size. You will also find many good places to use the leftover foam, especially if you have areas on your bike that get packed with mud.

The opening on the bottom of the air box is normally left open to allow drainage and larger debris to fall out. I use the Twin Air wash cover that replaces the filter and cage when I wash my bikes.

I use the green honda oil. Soak the entire filter and then let it drip dry for 24 hours. Its real messy but it works great. Make sure to get the honda cleaner too. It take the oil and dirt right out when you go to clean it. I have two filters. Stay away from the spray oil!

Any of the foam filter oils will work on this Twin air filter. I prefer the spray on foam filter oil.

There are many manufacturers of foam filter oil. As long as you get the oil that is specified for foam filters, you should be okay. My preference is the Twin Air bio oil or No Toil bio oil. Be advised that you will also need cleaner to remove the oil and clean the filter. These are specific to the types of oil also, either bio or regular. Do not try to use anything other than specific air filter oil cleaner as you will damage and ruin the filter.

Do you always have to oil up the air filter and if so what kind of oil or lube?
MotoSport Staff
2 years 3 months ago Location: Portland, OR, USA
MotoSportExpert
Yes, the foam filters do require you to oil the filter. Depending on riding conditions, the filter should be checked after each ride and cleaned accordingly. A dirty air filter will make your bike run poorly and if it gets too dirty, it can let contaminants into the engine which will severely reduce engine life. I prefer PJ1 foam filter oil and cleaner. Twin air also has their oil and cleaner which is good, and so does No-Toil.

ALWAYS ALWAYS ALWAYS!! You absolutely must use air filter oil, and some waterproof grease on the rim for a good seal. Any tiny amount of dirt or sand that gets past the filter will mess up your engine! Check the filter after every ride, and if it's not clean or if it's black or anywhere close to black, clean it with air filter cleaner and some warm water with soap, and then more water.

Yes you should always oil your filter. You can use spray on oil or the pour on just don't use to much of ether. I recommend the pour on oil put some on the filter and squeeze out all excess oil.

Oil is highly recommend. With out it the filter will be far less effective and motor damage could occur as a result. I prefer bel-ray filter oil and cleaner. I've also used pj1 spray on oil and cleaner with good results however it is thinner oil than belray so when riding in dusty areas I use belray.

Yes - the oil helps trap the dirt. I use Bel-Ray foam filter treatment, or Maxima FFT - the sticky stuff. I have not had good luck with the alcohol based filter oils.

YES! You must never run a dry filter. Always oil the filter. Make sure its clean and dry before you oil it. Everyone has a preference to what they think is the best, but any of the filter oils sold here will work. I like Bel Ray personally. Obtain a nice even coat by thoroughly working it into the filter. Dont overly saturate. Also you need a nice coat of grease between filter and air box. Without a proper functioning air filter your engine will soon be toast.

Yes. Unless you order a pre-oiled filter. Then after cleaning, you have to re oil.There are plenty of air filter oils out there. Just remember after you clean and oil your filter, it needs to sit for about 24 hrs before you run it in your bike

Always oil the filter when it's clean to prevent particles being pulled through. Any foam filter oil spray from an auto store should do just fine. Be sure to let it dry.

Yes, before use, saturate the filter with FOAM FILTER OIL. Wring out the excess oil, and let it dry out for about 30 min. before running the bike.

You should either let the filter air dry, or blow it dry with compressed air.

If you put it in a dryer you will damage the filter. This and most filters like this need to be air dried after they are washed. If you try to dry it with an air dryer or anything other than just leaving it in the sun it will damage the filter.

do not put it in the dryer, but you can put a nail in your wall and hang it on that to dry

Never put in the dryer. The heat will damage the product. Just let air dry and re-oil let it hang for about 45 mins and put in gallon size zip-lock bag til you are ready to ride. Just remember to install before riding... Hint... Put the zip-lock bag with filter on the seat and use some painter's tape to secure so you will remember to install.

It needs to air dry for best performance. Using a dryer will break down the material which will lead to cracks and broken down foam which allow dirt to get in.....then you've got BIG problems. Be sure to use your favorite oil and lube it up good, that also helps prevent dirt from getting in.

I wouldn't recomend it. Roll it up in a dry towel tight. Then soak it in oil and let it drip dry for 24 hours. Stay awsy from the spray oil.
