K&N Air Filters

[BoxsterLL11]

Just in case anyone is interested, EuroCar parts have a discount online deal going at the moment, I think until the end of the week (code is CRAZY70).
I have a 981 Boxster which I have owned only for 4 months but I have been using K&N filters for nearly 40 years so it was always on my radar to fit K&N's to the Boxster.
They normally retail for about £61 each (you need 2) and I got mine today from EuroCar Parts for £39 each.
They are an easy fit through the boot access.
They do not need oiling as they are pre-oiled prior to fitting for the first time and I got this response from K&N today as I had heard rumours about the filter oil playing havoc with the mass air flow sensors.

The oil does not come off of a K&N air filter when it is in use, even when over-oiled or in extreme air flow rates exceeding 1000 CF'M.
If somehow K&N air filter oil were to make contact with a mass air sensor, the oil would not cause the sensor to fail. We have intentionally coated mass air sensors with our filter oil, and monitored the sensors' output when installed in daily driven vehicles. These sensors continued to function normally, even after being sprayed and submerged in K&N air filter oil. K&N air filter oil does not cause problems with mass air sensors.

These are for life air filters and can be cleaned & re-oiled at 50,000 mile intervals.
You can buy cleaner/re-oil kits from various suppliers.
The K&N part number is E-0666

Good shout!

I have BMC filter in mine, previous to that I have had K&N filters in all my sports cars. Never need replacing with proper maintenance which saves on service costs over the years. Just don't forget to tell the guys/girls that are servicing your car, they may replace it with the OEM one

I also posted the same thread on the Boxster forum.

A few doubters re warranty etc but K&N state fitting their filters does not affect the manufacturers warranty.

Another owner said they have used the cotton filters for years and never had a problem with servicing by an OPC.

I just thought at this price they are a bargain for anyone wishing to fit them.

Fitted the K&N's yesterday, took about 30 minutes.

Worst part was getting the boot moulded carpet out & back in.

Even though the car has had 2 services by OPC's, the OE filters were dated from the build date and were quite black with feathers and other debris stuck within the filter elements.

The intake tubes also had a fair few dried out leaves that were beneath the filter cone.

Wish I was !!!

Like I said originally, I have been using K&N's since the late 70's at a time when they were not widely used or their name was not widely known.

I first used K&N's on my speedway bike when they were just being introduced to motorsport as the simplest mod to get more power out of a stock engine.

Engine performance mods have moved on considerably since then but K&N's reputation as a performance high-flow high quality air filter remains is as good as ever.

Why keep replacing and throwing away filters when all that is needed is to remove, clean, re-oil and re-fit.
