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 Eric Garron

In the past I have installed various individual and prefabricated air intakes on several vehicles. A sporty-sounding engine and a slight increase in consumption and performance were noticed again and again. I expected this replacement filter to be for my 2005 Saab 9-3 2.0T. This filter was a replacement for the stock air filter. It took me less than 5 minutes to install. First, I can feel increased throttle response and a LITTLE bit more power overall. Also, the turbo is now easier to rev up, which sounds great. I haven't been able to test the difference in gas mileage yet, but I think it should be a 1 or 2mpg increase overall. I'm really impressed by how much this filter alone can change the stock airbox and intake system. Great purchase, especially since I will never have to buy an air filter for my car again.
