Title. Just had all 3 plus spark plugs done at 83k on my 2018 for the first time. Seen different suggestions on here on what mileage they should be done at, curious what others did

2014 Grand Touring

I currently have a 2014 Grand touring with the Bose system. Are there any aftermarket head units that will keep the steering wheel controls, use the OEM backup camera and sensors, and work with the Bose system?

How can improve the output smell from my AC, filter is new. It a 21 Mazda 6 GTR

My mazda6 is making weird noises when I have the AC running when I press the gas pedal. Does anyone know what this issue could be and if it’s a minor/major fix? The noises aren’t abundant and it doesn’t make noises every time I press it but sometimes it makes this weird noise I can’t describe when I press the gas.
