This is how it looks after 60k kms. That's the distance SvRS tells me to change it, so I did today. Shopmanual states to change it after 30.000 kms in case of driving in dusty/sooth conditions. But I believe in my case 60.000 km is fine the way it looks. Never had any noticeable loss of BHP and never felt any difference in the past after filter change.
