K&N Filter Swap - 981 E-0666
I know K&N can surface mixed emotions from P-Car owners but I recently swapped the factory filters after 1k miles on a 981 Cayman S. I wanted to give them a shot because I have a dyno at my disposal and work for a SEMA and PWA member aftermarket automotive manufacturer unrelated to K&N. Therefore I am always curious as to how parts work, fit and perform outside of my day job.
Initial uninstalled observations:
K&N unit is slightly smaller than the factory unit.
The passenger filter is a collasal pain in the butt to get to at first glance.
The factory units are very dense but lack structural rigidity.
K&N fits exactly like factory filters and are secured with new screws.
Installation - very straight forward. Refer to a service manual if needed.
Testing:
77 degrees at 508 feet above sea level. 33% humidity. Mustang 1100 Dynometer
Two base pulls and two pulls after filter installation. About 23 minutes apart.
Initial gains are an impressive 7.9rwhp and 11.2tq peak gains. The largest gain made between 3700-4k RPM of 9.7 which was surprising.
Other Notes:
Induction noise noticeably louder to the ear.
Fuel mileage hasn't changed for the same trips.
Noticeably improved throttle response.

Good luck trying to find that shop manual.
"Search" is your friend. Also, try the Planet 9 forum. I'm positive that I've seen pictorial write-ups there.
Let us know how it works out for you.

f22c, funny thing about oiled filters is that we run them on our motocross race bikes that suck in nothing but dusty air and would never think about using a dry filter because they let in to many particles. (I know.. I'm late to the game on this post. I just bought my first Porsche, 2015 Cayman GTS and am wanting to do this filter switch)
