Excellent product for my 2015 Lancer SE AWC. I saved a lot in gas consumption in using it and I felt the extra power on my car. I recommend it to everybody Great job K&N.

I agree- definitely a noticeable increase in HP from the factory filter. Breathes a lot easier, accelerates better after the magic 3000 RPM mark on this engine, and even makes it sound tougher.

I received the filter quickly and have been using K&N's for many, many years with much satisfaction.
