Got my filters and just put them in. I'll evaluate them tomorrow when I go out.

I put the K&N drop in filters. The differences I can tell is it is a little quieter and a little smoother. The mid-range under acceleration is more melodic.

Yes a friend at my last job has been running the same K&N air filters for years, he just cleans and recharges it. Still like new

As for air intakes and being around the Z racing scene it seems the Z1 long tube intakes and Stillen Gen 3s are great intakes (with a tune) but the Admin Tuning intakes are the absolute best if you seek the most power gains.

Can anyone tell me what would be the exact replacement filter (dry or oiled) for the stillen gen2? I'm need in of 1, mine developed a year and I cannot find the information. Tia

They use a K&N air filter cone style air filter. My Stillen Gen 2 came with a oiled K&N air filter cone style. Either get in their and measure the diameter and call K&N air filters with your measurements or call Stillen directly and ask what is the part number of the cone style air filters they are currently using with the Stillen Gen 2 kit. Stillen recommends either replacing or cleaning and oiling your air filters once a year under normal use.
