Air filter
Hi, has anyone ever installed one of these?
I've had these on my golf and jeep but was wondering if it was a good idea to install one on my 911.  The regular air filter is so hard to re-install and one of the back clips was already broken when I bought the car. Thank you in advance. Sent from my iPad using Tapatalk HD

I like K&N and use them on things that run on snow and water. I had one on a chevy 4x4 and didn't like the amount of fine dust that was getting thru into the intake!!!! My SC had one in it when I bought it, I took it out, I also kinda live in a dust bowl.....

If you do a search for "cone filter", "after market intake" and the like you will get many hits (for example):

I like the idea of reusing the same filter and the air in Montreal is almost clean : P
I bought a k&n filter same shape as the original filter but it seems kinda loose (not as tight as a regular orange filter). Sent from my iPad using Tapatalk HD

K and N is a great way to fill your intake with dirt. I know from experience on 3 different cars including the 911. Yes I cleaned and oiled the filters at the recommended interval. I now use paper filters.

I've had the MSDS cone filter on my car for about 5 years.I clean and oil it every other oil change, or about once a year.When I take it off for cleaning I wioe the inside of the throttle body
I find very little dust inside, not enough for me to be concerned. Have you seen the GT3rs 4.0 motor from the factory ? looks like somebody at the factory did not get the memo about K&N filters....

race car motors are usually rebuilt every race
you may not see dirt build up with a K&N or similar because the particles are small enough to go all the way down into the engine use the correct paper filter - the K&N offers nothing |

For those of us with Webers or PMO's there is no paper filter available. So for us it actually does offer something... a filter that fits.
As an aside, i think people have been using these for 30 years now so like oil, gear oil, everyone has an opinion. I assure you that 99% of the people using these for YEARS have NO issues and arent rebuilding their engines.  Nor is Porsche rebuilding the GT3's it is selling new with these. Quote:

I would agree with that. I actually wished someone would make a paper filter for the Weber/PMO. Now that they are selling PMO ITBs for aftermarket EFI I would think there are enough non-racers out there that could benefit from a paper filter.
