After installing the K&N drop in air filter in my 2006 Nissan Altima 3.5 SE I have noticed a huge improvement in exhaust sound as well as boosted acceleration and overall power.  This morning my 2006 Nissan Altima met its match when a Lamborghini Countach left me in the dust, but when I poured on the gas I was amazed how easy it was for my Altima to catch up to the lamborghini, and I highly doubt this would have been possible if I hadn't replaced my factory stock air filter with a K&N air filter!  I also have the picture to prove that I caught up to the lamborghini as fast as it had passed me by!

I have used K&N air filters for many years, and was very happy to learn that K&N made a filter to fit my Lamborghini Miura. The filters fit perfectly, and I am very happy with them.
