Just replaced the air filter for the first time on my 2009 S60 2.5T and have two questions as a result.

1. It's difficult to unhook the rear part of the cover and even more difficult to rehook. Is there any trick to this? I tried all kinds of things but nothing seemed to make it any simpler.
2. Any good filter suggestions? I used a Mann replacement filter. AMSOil has an interesting filter they call the Ea line. Anybody have any experience with these? Any filters to stay away from?

Thanks

 

How many miles you have? curious

Use a big screwdriver on the back end of it or pry bar and angle the top portion in 1st.

I like K&N !

 

Around 8,000 miles. I know the old filter probably didn't need to be replaced, as I don't live in an overly dusty area, but I like to do these things about once a year. I figure what the heck, it's vital to the engine and only costs about $23 with shipping.

I tried using a screwdriver and a knife as you described, but they were not much help. It's good that it's a tight fit, but when things fit that tight and are made out of plastic I worry about breaking one of the clips.

I read a little about K&N filters and one thing that worried me was that they seemed to allow a little more of the finer particles to get through. At least that's what some of the tests said. Whether these tests are true I could not say.

 

They do, just more airflow.
