Replaces stock air filter element
Part #33-2232
Retails near $50 - seen here: http://www.gtmotorsports.com/catalog/product_info.php?products_id=488&osCsid=8789b6599a29991c36fd7872c8ac3e20

I had this filter installed for about a month or so before I got a different style intake. I just cleaned and re-oiled the filter using the authentic K&N recharge kit. It is in like-new condition, oiled and sealed in plastic, and it is ready to ship.

First $30 takes it (shipped via priority mail)
Paypal accepted

Here's all of the applications- http://www.knfilterchargers.com/search/applications.aspx?Prod=33-2232

...and a pic of the recharge kit to show you I actually have one

It's going on Ebay tonight if no interest is shown...

I'll post a link here if I put it up for auction

Thanks, Andy

It's up for auction, but you can still use the 'buy-it-now' option to get the same deal offered here.
