Is there a difference between cheap and expensive Airfilters

This is something I've thought about.
Is the "expensive" TwinAir (or similar) airfilters actually and better than the lower priced options?

I usually buy a pack of 10 filters when I get a new bike and I'm always choosing between getting the lower priced version or a name brand.

Some airfilters are junk and don’t fit right. Don’t ever buy a K&N filter.

I’d recommend buying Tusk filters. They’re dirt cheap, fit good, and semi-disposable.

If you're not mixing gas, you're not haulin ass.

Thanks for the reply

Yes I'm mainly talking about the quality of the foam etc.
I've never had an air filter with a bad fit/seal even on the slightly lower priced ones (allthough I'm sure there might be some shitty ones out there)

The DT-1 filters are good quality, and periodically they'll go on sale and you can buy a few at a time for relatively cheap

I always run uni or twin air. Nothing else is really an option for me since ive always had good luck with those 2.

Pro-X makes excellent and cheaper air filter too.

Ran them for over 20years... I was given a no toil and didn’t think the quality was worth a damn!! I know people love them and swear by them but I thought they were garbage... my 2cents

Not only do they use super high quality foams, but there's a neoprene seal where they contact the airbox for a dust-proof seal without needing any grease. Best airfilters in the dirtbike world.

Another vote for DT-1 from me.
Very good quality filter and very well made. I always use a DT-1 for longer Enduro races, or any track that is notoriously dusty. As above, they seal on the airbox better than any other filter IMO

DT1 here as well. The seal really helps. I usually just spray some filter oil on the seal surface and it never has any evidence of dirt making it past.

I really like the DT1 filters with the extra "mud" layer of foam. I can't tell any power difference and they seem to work great.

I've been using high flow filters other than the color they feel identical to Twin air

you guys soak or spray on oil after cleaning?

|

No Toil or Twin Air for me. I was using the Maxima $10 throw away filters for a while. I was getting them for under $4 for a two pack...but that deal has since gone away.

I spray my filters with PJ1 red air filter oil, inside and out, then work in the oil by hand. Air boxes have been spotless for 15 years with the same method.

2nd this. I like Pro-x filters, along with much of their other stuff. OEM products at a cheaper price

I spray mine with maxima or pj1 oil and work by hand.

what do you guys use for a wash method. I use pj1 as well

So why are twin air filters one piece, but uni filters two piece?

Also, for ktm models, the oem twin air is actually cheaper than the aftermarket twin air.

And another vote for pro x.

I used no toil filters for a long time but they kinda got a little stretched out

I usually spray mine inside and out.

I have used Twin Air and No Toil for almost 10 years, and always would end up having failures at the seams between the foam. A few years ago I picked up some DT-1 filters really cheap and won't switch back - the DT-1 filter quality is way better. I've been running the same 2 DT-1 filters for 2 years now without a problem (riding 3x per week except for winter) .

I have used those preoiled filters that are 10 bucks shipped . I do oil them again before I install and have never seen anything get past them . I usually buy enough for the year and just shit can em , for 10 bucks it's not worth my time
