Have You guys heard of these filters,they are australian made,I dont know if they sell them in the states. they are made of foam,There filtration rates are as low as 4 microns & there Flow rates are Equal to k&n filters.They claim to be "the worlds best airfilters"
Best of all they are half the price.
Im going to get one soon hopefully.

 

Half the price?

Never heard of them.
I feel good just using Toyota air filters.
People here have gone a couple of hundred thousand miles using regular Toyota and off the shelf filters.

 

UniFilter primarily caters to the MotoX bike crowd and their filters are used world wide. IMO they are a decent filter but after 10 or so rewashings/re-oils the foam can dry a bit and can come apart which could be bad especially on a turbo equipped engine but at about $30 a pop (plus a couple cans of filter oil) for a couple years of use would be worth it to some.

I've read good things about their filtration under very dusty/dry conditions on motorcycles but never read much on their filters for other applications but I had a decent experience with a custon made Unifilter (made to replace HKS Powerflo filter) for a couple race seasons in my Eclipse.

But maybe a for an NA truck they might not be cost effective but somebody's gotta be first.

 

Yeah they were originaly made in the US for motor bikes,but this australian lot have taken over, & now make a good range of car & truck filters.

 

I saw one when I was in AZ recently. It was an impressive piece.

However, I doubt is flows or filters any better then AMSOIL two stage foam filters.
