I purchased the air filter when it was out of stock, so I knew I had a bit of a wait time, but when it did arrive, I was very satisfied. I'm a previous customer, having put K&N filters in both of my previous cars. I'm very happy with the increased throttle response I get from the reduced restriction, as well as the fact I never have to buy another filter for the life of the car. My previous car, a 1996 Ford Aspire, didn't have a direct application, but the airbox dimensions were exactly the same as the Mazda Demio's, which you do have a filter for. I'm glad you took the time to design a filter for the 2014 Mitsubishi Mirage. It definitely helped lessen the effects of the lag associated with electronic throttles. I didn't particularly notice any power increase, but the other benefits are worth it. I would definitely consider purchasing an air intake system if you decide to make one for my application.
