Nearing 15k in my 2024 SC SEL. I want to keep my warranty intact, but I want to do the engine air filter replacement myself because I know it’s not hard and the dealer wants to charge me a ridiculous amount to do it. Where is the best place to buy the filter? I’m seeing a lot of third-party OEM parts sellers online but I can’t tell if they are legit. How do I make sure I don’t void my warranty and have a record of it? Just keep the receipt?
