Has anyone used K&N oil filters? I'm not a big fan of their cleanable air filters ...

I'm currently running one on my 997.1 Turbo. I saw good reviews on Amazon, and it was cheap. I still have a few thousand more miles 'til it gets replaced so i can't give any insight yet.

debated about it but could not find any spec except on the k&n website that says "premium" filter material. Was 1/2 the price of the mahle or prosche OEM on line, bur decided not to chance it.

No way would I try an aftermarket part for something so important as an oil filter...cheap out now potential thousands later...thousands...

It's easy to assume the K&N isn't good, or isn't as good, as OEM. Since Porsche doesn't make filters, even the OEM Mahle is 'aftermarket'.

It's hard to find good info on BITOG because 'K&N' is too short a search term.
K&N advertises that it meets or exceeds all of Porsche's specs and that it's 99% efficient. If that efficiency is based on the standard 20um standard, it's better than OEM.

It's 3.5h round trip to buy a filter at the dealer, so I'm going to have to order one on line anyway. I'll order 1 K&N too and do a visual comparison.

I should have mentioned... This isn't about money. I'm happy to pay for quality and peace of mind, but I also need evidence. I have no evidence the Mahle is any better, or even as good.

I see you have a 2011 C2 which probably has a CPO warranty?
Anything you put on/around your engine that is not Porsche recommended (not sure K&N is?) will come back to haunt you if you need warranty work.

I went through this a few years ago on a CPO Porsche and it took a lot of back and forth talking to get them to cover the work.

If a Porsche oil filter fails they will quickly repair your engine... Would k&n do the same?

The Porsche filter is designed for the 9A1 Porsche engine from the start. One thing I would not mess with...

OKB

used k&n for 30 years in every car Ive owned, never any problem, but now using bmc because a little less oily and cost about the same. Look on ebay

Aren't oil filters usually pretty oily?

Smitten

Thanks for the thoughts guys. Good discussion.

Really, I'm not suggesting the K&N is some great filter. But I really don't know that the OEM filter is all that great either.

The Porsche filter that is "designed specifically for the 9A1 engine" is also used on:
911 Turbo or Turbo S - 2010-2013
Panamera (all versions, except diesel and hybrid) - 2009-2013
Panamera or Panamera 4 - 2014+
Panamera GTS - 2014+
Panamera Turbo or Turbo S - 2014+
Cayenne S - 2011 or newer
Cayenne Turbo - 2011 or newer
Cayenne Turbo S - 2012 or newer

I remember reading about some negative MAF affects when using k&n
For example... (The search turned up quite a few along the same vein)

You are talking about air filters and the oil they use to stop debris doing damage to the MAF wire.

This thread is about oil filters.

Does anyone even read threads anymore before responding? Sheesh.

Anyway op, k&n is a reputable company and their oil filters are fine products. They won't harm your engine. Use it if you like. It's not like you're ordering a lot of 100 filters from alibaba for $3.50.

Ah ha, I stand corrected ;-)
