I am planning my full service once I have all my parts needed.
One thing on my list to get, is air filters.
Are the K&N ones worth it, or should I stick to genuine ones.
I am not looking for performance gains, just life time, more than anything.

I suggest OEM Hengst, Mann, Bosch and Mahle if your vehicle is going to be a 'normal' driver.
