I've had a K&N air filter on my 1987 911 for 10 yrs with excellent results. I use the K&N cleaning kit annually and the filter still looks like it just came of the box. As for the 2011 Murano the new filter seems to have increased horse power and performance.

I replace the air filter with a K&N filter each time I get a vehicle. It improves the performance of the vehicle and I never have to buy another replacement filter again. They just need periodic cleaning in accordance with K&N recommendations.
