I take back what I said about the TwinAir air filters

Recommended Posts

OK, three clean filters; discussing visual qualtiy based on inspection, light transfer, and build quality (size and thickness of sealing area)

*It's my contention that the thicker, larger, and more dense the sealing area, the better*

 

Twin Air  - reasonably thick and large sealing area, with decent poursize (see flashlight test). A decent filter, for sure.

Uni Filter - terriblly thin and small sealing area, with gigantic pour size. A Fail, in my opinion.  So much for Uni coming to help us out.....  Uni filters used on other bikes were huge at sealing.....

Pro-X - larger and thicker sealing area. Very small poor size. (see flashlight test). Too me, the best of the Three by far (based on this 'test') . Even in the flashlight tests, you can see the camera changed it's Iris to comensate for the reduced light coming out of the filter. Visually, without the camera, the Pro-X blocked the most light.

My vote is for the PRO-X FILTER for my Beta, from now on.

Are you gonna use smoke for the leak test?

Nice.  Good information in your post Kran. 

 

Pore-size.  Smaller is better.

Not sure how you'd test for this , but seam strength is another test that is affected by cleaning agents and filter oils. I can tell you after having some failures on No Toil filters(they used to sell those) I went to Twin Air and they lasted forever. until I'd burn a hole from a backfire or some other issue. Never did I suspect Twinair was at fault. They are the standard of the industry. I love their oil and cleaners as well.

No, I am going to put the motor under load (slip the clutch in gear,  on the ground)  and do the spray brake cleaner test again. 

I don't think idle vacuum is enough to tell us anything meaningful.  I want the motor to really suck.....

I've noticed an improvement in the design of the air boot and filter cage from the 4T '13. to 2T '18. models.

The 2T '18. model has a raised edge on the filter cage, where 13'. was smooth. It seem to me that the seal is better because of it. Is your '16 like this?

Clamping force is also good and I can't easily lift the filter from the base with my fingers.

If you think that a bigger sealing area of the filter may help then InnTeck filter mentioned in another discussion is better than the TwinAir. 

I installed the InnTeck the other day but have yet to ride with it. Material seems firmer than the TwinAir.

Just a thought on pore size from my experience in filtration. While the smaller pore size appears to be what you should have. It would reduce the inlet air which maybe good however the filter would flex from the motor's suction. This suction would pull on the sealing surfaces and leak IF you have an issue with flatness or retention on the system. As the filter's pores fill with dirt you could have reduced running quality and or more intake dusting compared to a larger pore filter.

I had just taken off my BIL's 2008 CRF 450X air filter and the filter cage is backed by a double layer of fine screen.  

Our Beta's do have the single screen which is better than no-screen.  

(Some)Guys do run pre-filters/filter skins for that extra layer of fine-protection so there is that.

I stopped using Twin Air's because the seams were coming apart after a few wash's in the the No Toil detergent, after watching there video last week I may have found out why.

I run straight hot water into a 5 gallon pail mix the soap in and drop five filters in the bucket to soak, at the end of the video it says don't use hot water, I did switch to the Pro X filters and the seams do hold up better the the hot water.
