Easy to fit (having said that most modern cars are pretty well designed these days, so replacing the air filter is simple) One installed (about 3 mins) I took he car for a test drive and noticed power difference across the rev range, it also feels like you can actually accelerate, it's turned my slug into a bit less of a slug. Thanks K&N
