Très bon produit

Product fitment and quality are excellent. It is basically plug and play. Good reasonable price for the good you receive. However I did not notice significant performance improvement over the stock paper filter when you drive it. Perhaps you need to perform dyno test to be able to see the improvement.

Great filter, definitely an improvement over the oem BMW air filter (E36 320i coupe owner).
