Description:

I have a brand new K&N Air Filter for sale, I only opened it to do a test fit/mock-ups while building a cold air intake on my single turbo FD. Unfortunately this filter was a little too long to fit in the space I had available, so my loss (and failure to verify all dimensions before buying) is your gain. Asking $20 plus whatever it costs me to ship it. Filter specs follow:

Flange Diameter - Filter will fit a 4 inch, 3.5 inch or 3 inch outside diameter (OD) intake piping; filter comes with rubber adapters for the multiple sizes (see pictures). Also includes worm gear clamp.
Filter Length = 5 inches
Total Length (includes mounting flange) = 6.5 inches
Base OD = 6.125 inches
Top OD = 4.75 inches
