I bought this air filter for my 2006 Saab 9-3 Aero 2.8L V6 Turbo. After ordering it my Saab authorized mechanic told me to be aware, that it may not work, and cause the car to not run properly. He also said I could trigger a check engine light using this filter!after hearing all of that I was worried. Once I received it, I installed it immediately! It took about 10 minutes. Then I was off on a test drive! Right away I noticed a difference! Acceleration was smoother, and quicker! It even seemed a bit more throaty! So I went through the city, and headed for the highway. I was at highway speed before I was on, just going up the ramp! I was, and am very impressed with this filter! I've even noticed more milage between fill-ups! There are no check engine light issues at all! This filter is truly amazing, and I'm completely satisfied! Now I'll never need to buy a new filter! That alone is worth the price of admission. I'll use K&N products for every vehicle I ever own! I highly recommend there products!
