James M-S said:I put some on a couple of weeks ago. Can't feel a difference but the exhaust note sounds smoother/less gruff if you know what I mean.
I don't reckon it's worth full price, but for the price of a tank of fuel, you may as well.
Very easy DIY, and a chance to give the air box cover a good clean.

remember they are reusable so will save in the long run. when you do clean it and re oil it make sure you wrap it in kitchen paper towel and put it overnight in the airing cupboard to steep . that way you will avoid any manual over oiling fouling the maff as its hard to reoil them manually as lightly as they are oiled new. more cold air in is good for the engine. :grin: :thumb:

nz911 said:Going to be the only person disagreeing by the looks of things, but everything I've read indicates the BMC filter does very little good, and adds risk of MAF fouling. The Porsche OE filters are great, and your money is better spent on other things. If you're determined to use them, the general suggestion is to treat them like a disposible filter and not re-oil as this tends to result in fouling, although the suggestion above may be enough to mitigate this.

+1, this is spot on I'm afraid. Surprised so many are unaware of this.
