Hello, new here. There might be a post on this and my apologies in advance if so. I have 2019 AT4 with the 6.2l with performance pack that included the air intake system. Took my truck for it's first oil change and the dealer (where I did not buy it from) they told me they couldn't service the filter or clean it....wtf?! Any direction how I go about cleaning it would greatly be appreciated Thank you.
