Review on 🚀 K&N Engine Air Filter: Premium, High Performance, Washable Replacement Filter for Saab/Vauxhall (2002-2011): 9-3, 9-3 Series II, Signum (33-2337) by David Dober

Ideal for Saab 9-3 2005 with 2.0 turbo engine. The product was well packaged (the filter came in a sealed plastic bag in the box which kept out the initial oil and dirt). Ideal for air box. Tip: Vacuum before you start so you can vacuum the airbox as soon as it opens. I have noticed a slight increase in fuel mileage, this may be due to increased K&N mileage because the old stock filter was dirty, or a combination of both. the acquisition costs of a conventional Saab air filter, the investment pays for itself after three regular filter changes.
