k&n are they worth it?

The filteration is every bit as good as OEM filters.

I'd be keen to see the independent testing for that claim, as there's plenty online showing they aren't.

They let more particulate through to achieve the higher flow rate, fact.

Most people are narrow minded with these as they've paid all that cash and don't want to admit to themselves.

I've tried both in cars and bikes and kept an open mind, and went back to stock.

As I say, each to their own, but no point offering 'advice' on unfounded claims or non-independent testing.
