More than 10 years I used K & N filters in 4 different cars, but stopped since 2009. Modern cars do not like oil vapor from these filters, problem with MAF SensorI've always used a K&N air filter in my cars. I just noticed that one was available for the XC60. Has anyone tried one yet? In my other cars I always got better mileage and more power.
I use one. Between that and removing the charcoal filter (RIP Earth), you get maybe a few percent more power/torque? It's nothing massive, but as I have a T6 with P*, I figure I'll take the tiny bit extra.I've always used a K&N air filter in my cars. I just noticed that one was available for the XC60.

Eyeroll.Running a K&N is one of the worst things you can do to your car. You’re just killing the engine every minute it runs with a K&N filter.
Please don’t do that to your car.
Increasing the power of 8-10 hp with the air filter, this is the best joke of the centuryAccording to a swedespeed member here (I think Grecian Volvo), it's good for 8-10 bhp (if I remember corectly).
Yes you really, really should. In fact, leave the Volvo and VW engineers to me. I work with these guys and I'll be happy to let them know louisparis considers performance air-filters, snake-oil and has physical and experimental proof to prove it! I can already see K&N, AEM, Injen and the likes losing sleep over declining sales.Increasing the power of 8-10 hp with the air filter, this is the best joke of the century
I urgently need to inform engineers Volvo, Ferrari, Porsche, Mercedes, BMW, Toyota, VW ................. that they are stupid and do not know about this information
Yes. Makes total sense. And I bet every single person here respects your opinion to treat your car the way you want. No one's gonna argue with what you like to do with your car (especially when there is absolutely nothing wrong with using either of the Air filters being talked about).....so I'll continue NOT using K&N filters.
My first guess would be, by reducing the restriction provided by the stock air-filter, resulting in a freer-breathing intake. The turbocharger/supercharger can suck in all the air they want, they will be restricted by the filter element (hole) size. By giving it a lesser restriction, you basically make them huff and puff less!If the air going into the cylinders is already compressed, how does this air filter get more air in there?
Hundreds of engineers and professors in Japan, Germany, France, Italy , UK ....... are stupid and do not know that I can increase power by 8- 10 HP for only $ 40 (with air filter)Thank you p07r0457, for explaining what YOU feel. As I explained earlier, everyone is entitled to their opinion and I'm sure you have convinced yourself about all that you have written in your post as the truth! Good for you.
As for me, I trust my knowledge gained from my Masters and my Doctorate in Automotive Engineering and Internal Combustion Engine design enough to understand a snake-oil product or a random forum post from a self-proclaimed Engine flow design and CFD expert! :beer:
