Like the title says, foam filters offer far better flow characteristics, and filtration over the thin cotton oiled filters, however as foam gets dirty its flow drastically gets reduced...but its incredibly easy to clean, as simple as putting it in the sink and washing all the dirt out and letting it dry.

reason for bringing this up is with the complaints from people saying the oiled filters damage teh sensors on the cobalt, then gm not covering it, i think foam is the way to go!

 

You oil foam filters as well don't you ?

 

Yea I believe you have too. I have a dirtbike and I have to oil the filter that goes in it. The filter is foam as well

 

no you dont, foam itself is the dirt blocker, dirtbike is different, the conditions you ride through, but foam filters dont need oiling, you simply put it under water and literally squeeze the dirt out like a sponge.

 

I had foam filters on my motorcycle (street bike) and I had to oil the foam filters as well.

 

I do not think that foam filter flow that well???? and might clog easer.

 

foam is a terrible filter media, it also breaks down into tiny little pieces that will happily travel into your intake and into your engine.

 

i apologize, foam filters are oiled as well, lol

but here is a quick test i pulled up, cant verify the numbers however

Oil only damages the senesors if you put to much on.

 

Im totally going foam filter when I start to tune (weapon-r) the numbers on their secret weapon intake for the redline are ridiculous!!!!
