My buddy was lookin up Z parts the other day, and this company called IMPUL kept coming up. He said that they are big in Japan, but doesn't know about the gains. Anyhow, I was wondering if anybody had any IMPUL parts or had heard anything good about them. Thanks.

 

I am curious about Impul as well. Japanparts.com has a Impul sports air element on their site along with 2 Nismo elements. I'm wondering if it is worth the extra $40 over a K&N.
