i've installed dozens K&Ns and intakes on all of my cars and quads and have advanced experience when it comes to cars, mods, etc. The Cayman S is about 2 weeks old.
I read the article on the K&N and followed step by step... up until I tried installing the K&N (E-2295) and got stuck. The end of the filter that goes over the intake fitting will not fit!! I tried for over a damn hour and gave up, reverting to the old filter.
Mainly it is so tight in there and awkward to work on a mid engine car.
The rubber on the end of the K&N is flexible, and there is a hose clamp that goes over it (not mentioned in the articles on this site).
If anyone can help... or offer advise I would appreciate. Anyone in the Orange County Area (CA) that has done this successfully and wants free lunch please PM me!
thanks,
chris
I’ve installed the BMC filter which is very much of the same breed of your K&N. Installation was straight forward, with no hiccups. I’m in the So Bay area up the street from you, if need of help.
PS: I've moved your thread from the Chat Forum.

It appears that you are not alone. Does this help at all?

Santa Fe beat me to this one, you will see by the thread that he linked I had this very frustration. It is a very tight fit. What I did to finally get it on is the following:
1. After I followed the steps in the article, I put some WD-40 on my fingers and lightly coated the outside of the ring in the airbox that the filter goes onto.
2. I took a hair dryer and heated the rubber ring of the K&N filter. I continued to do this until the filter ring got softer and began to stretch a little.
3. Put some WD-40 on the inside of the filter ring the same way you applied it to the air box.
4. Forget that clap, it is still a tight fit, you will not need it. Start at the bottom and pull the filter up and onto the air box lip. Like I said it is still a tight fit, but heating the ring helps.
Good luck, it is frustrating and a pain in the butt. Hindsight, I would of gotten a BMC or EVO filter.
I fitted one to mine , I had problems but found it went on easy without the jubile clip , so I bent the jubile clip to the exact shape , then it fitted no problem . Wish I hadn't bothered though as I could tell no difference in performance or sound so fitted an Evo intake instead
how much extra HP do you get with these ? it seems like a whole lot of work for what you actually gain by having it . am i wrong ?
To be honest, K&N has not run any dyno tests on the Cayman to verify any HP gain with their air filters. You can check HP gains here:
K&N Engineering, Inc. - Product Horsepower Gain
Having said that, most vehicles that they have dyno tested have a HP gain of 8-15 HP on average. The benefits of K&N filters is increased air flow and the fact they are re-usable. But as I mentioned above, K&N have not tested the Cayman yet.
Here's an interesting read:

The problem with an oil based filter is people forgetting to clean them. Oil + dirt will equal less h.p. over time. If you use these be sure and mark your calendar to clean it every few months. Most don't and defeat the purpose.
I got the same filter K&N havent dynoed yet but I did the same thing.
-put wd40
-heated it up so rubber would flex easier
-used the clamp
I'm pretty sure the HP gains will be there. at least 4HP cant beat it for $40.00
