After a couple of filters that didn't fit I finally found one that fits the engine and offers a freer flowing K&N option. But since this form a 1990 Porsche 911 3.6l the K&N best price I've seen is about $85 and will get one in the future. For now here is the paper version.

Porsche 911 K&N fits. At $80 It was steep but eBay had 20% off. Lost a little filtering area with the thick rubber holding the media. Has a nice whistle under load.
