Excellent quality filter
The usual Bosch quality and does exactly what it needs to do. Comes packaged well and is super easy to install in the cars air filter box. After replacing with this the air intake is able to breath better leading to restored performance and better engine health. Well worth it for the price, I would highly recommend.
