Best air filter?

[Butters]

What air filter is better? Uni, Twin Air, or K&N? I have a K&N now and I like it but was wanting something cheaper but still helps alot and maybe adds hp. Which one would do the trick?

I used to run a K&N but I didn't feel safe with it so I changed over to a UNI...

I highly recommend sparks racings air filter. I love mine and i got a really noticeable difference from my stock one.:macho

[Butters]

how much hp does the sparks put out? is it foam?

[northeast400]

Twin air, I love it and no air in the intake

If you allready have a K&N put an outerwear on it !! that's what I did work's great......

I dont know exactly what sparks puts out but it was a noticeable difference.

I would stick with foam myself. I used to run a K&N and now I am running the stock until I get a new one. I believe the UNI and Sparks are the same. I am going to get a No Toil or UNI.

i run an outerwear and i still see small particles on the inside. i am thinking on getting a foam instead. so what would be the best with the best hp put out.

UNI only way to go.

Keep it clean and freshly oiled for best flow.

I clean mine 2 or 3 times with Simple Green let it dry for 24 hours
(always rinse from the inside of the filter to the outside so you are washing particles OUT of the filter not further IN.

Then ad the UNI filter oil, make sure its spread out evenly and on there pretty thick.
I let it sit for a few more hours before it goes back in the airbox just to let the excess run off instead f gunking up the bottom of the box.

anyone have a pic of the sparks?

Im converting over to UNI..Dont get me wrong the KN is a excellent filter just sorta a hastle to need the charge kit just to clean it,unlike the UNI

i love my uni and it makes a very noticable difference. plus its way easier to clean and take care of than k&n!

I use UNI. Other then the stock, I have not used any other filter. I like it a lot.:blah

Uni with no toil oil. Easy to clean with the no toil
