I cleaned my garage out and found a new K&N cone filter in a random box. It originally came with a DC Max Air intake for a 99 Civic. I used a different filter with it, so I just shelved it.
It has a 3" inlet, 7" long, 4.5" diameter at the widest part.
I don't have the clamp that came with it, so you'll need that.
$30 shipped
e-mail me because I'll probably forget to check this.
