Good Air Filter
After Honda service dealership quoted over $120 for both engine and cabin air filter replacement, I thought it was just ridiculous and wanted to try out installing them myself. This engine air filter fit perfectly for my Honda 2015 Accord, and was easy to install. Quick 15 mins saved me over $100 and I can't be more happy. Definitely recommend this.
