Im looking at Uni-filter, kn w/ pre filter, and twin air filter. Just wondering which is the the better value? How well does the UNi and Twin air do being foam filters, they seem to be the cheaper and have notice that a lot of you have UNI-filter. I will be running a HMF utility exhaust, and a dyno jet kit with probaly the UNI filter, what jet do you run? Would it be same as the KN? Any opinions will help. thanks

I prefer the Uni because the foam filters the air better. The K&N will let more air in, but if not constantly cleaned and oiled it will let more dust in as well. The prefilter will help that a bit.

Not many folks run Twin-Air filters that I know of around here, they seem to be suited real well fo rthe dust out west. (I think Raveer has on on his Rinny)

We run the K&N's with OuterWears pre-filters. I wouldn't run a K&N
without a prefilter where we ride since it is so dusty.

I run the K&N w/out the prefilter, Is this really bad, should i get one? Or can i survive w/out one? I think there only about $15.00 from highlifter, so it's not a big problem to get one.

If it is really dusty where you ride, i would get one. I paid $9.99 a
piece for ours at www.rockymountainatv.com

would you have to rejet if you add that because you already rejeted it without the pre-fliter

You shouldn't have to rejet. I ran mine for about a year before i rejetted
with no problems.
