K&N Air Filter
A very good after market addition. I fitted one to my 2015 Astra 2litre Diesel and noticed a difference straight away, no perceptable restriction of air flow. This is the second K&N filterI have bought, a previous one on an earlier (2011) Astra 2 litre Diesel with which I was very happy. The ability to clean and re-use the filter is an added advantage. When the time comes I shall fit one to my other car a Mercedes A180 Diesel.
