    "I've had these in my last 2 cars a Miata and Altima with great success for both, Airflow improves with increased horsepower and slightly better gas mileage. (and both on small e cylinder engines-the V-6 should be even better) These filter will outlast the life of the car and cleaning, if needed is a breeze. The guys at CarId were helpful in order placement and shipping was fast, packed well and an overall seamless transaction. HIGHLY RECOMMENDED!"

    "Always use K&N filters in my vehicles. This one installed easily in 15 minutes with help from YouTube. My car idles smoother and has better low-end torque with less turbo lag. Mileage is slightly improved especially in city driving but driving is more spirited so that cancels out any gains. "
