So I bought my RS with a one-off custom air intake. It looks legit(see pic) and runs well other than a bit of whistle at start-up and low RPM. My car is not tuned. I'm wondering if I should keep it or put the stock back in. I'm not planning to the car for a couple of years(once I pay it off). When I got the car it was 16.8 Avr MPG and I've got it up to 20.9. I do drive the car aggressively. But only for short spurts and not every day. I feel like I should get better MPG and be thinking I should put the stock intake back on.

Thanks for the help.

Thanks for all the feedback! I'll keep the intake. I'll put a new air filter and senser The car only has 10k on it so I hopefully don't have to do anything with spark plugs.
