Review on 🚀 Enhance Performance with K&N Cold Air Intake Kit for 2013-2018 Nissan Altima 2.5L L4 (69-7064TS) by John Springer

The product is exactly what you would expect from K&N. QUALITATIVE! The goal was to increase gas mileage with cleaner air (I swear by K&N filters), which didn't happen. I have the same mileage. The increased power was a given and the car was definitely more responsive. A little extra noise from the engine reminds you of old style 4-barrel carburetors as you step into the powerband. It's a nice upgrade for the 2.5-litre engine, but a bit pricey considering the fuel economy hasn't improved.
