Product: Air Intake Filter Brand: EPAuto Positives: Super affordable and compact. Easy to remove and install, just loosen 4 screws and that’s it. Made with quality and durable material. The filter provides ideal airflow for the engine to function properly. Negatives: None. Overall Impression: I needed a replacement filter for my wife’s car and I didn’t want to spend a small fortune. This item was practically a steal at the list price. No need to spend more money, all the quality and longevity can be had with this filter. My wife drives her car almost every day and that means it gets a pretty good amount of use and lasts about 12 months until I decide to change them again. I would definitely recommend this product to others looking for a similar product.
