More power and better mileage
Put this in my 2017 CRV and have noticed much more pickup and better mileage overall. Usually I average 22mpg with mixed driving and this has me hovering around 25mpg and I get to have extra power on top of that. Install was straightforward and a breeze. Whole project is done in ten mins and your car is instantly more fun and getting improved MPGS

Improves the air quality of you vehicle
Perfect fit. You can tell the difference in the quality air recirculation. Without a doubt an improvement over inexpensive filters. I highly recommend replacing any auto air conditioning and heating with this filter.
