Improved airflow to my car, didn't change fuel economy or really big difference in performance, only big difference is the engine sound. The only reason I put a K&N on my 2013 Chevy Sonic is because the Chevy Sonic air intake is made of silicone or rubber and tends to crack after about 40,000 miles.
