I think I have the info you need Dave. My Son got me a pair for Christmas from Advance Auto. I just put them on recently & saved the empty boxes to put my orig. Xfire filters in for storage.

Advance SKU # 17403004

Mfg. # (K&N) 33-2290

My Son said they were hard to comeby from Advance. They were shipped to me one each from Charlotte N.C. & Phila. Pa. to fill his order.
