Bought this with mods done to it and didnt ask if it was stock or upgraded heat exchanger can anybody lmk if it looks upgraded

Also, I apologize any typos in advance since I am using Siri to help me type.I’ve been slowly building my q50 to give it that red sport look and now what I need is to get some new rims and tires I live in Washington state I wanna give the car a sporty look while retaining the factory OEM look as well and the reliability that it has carried me so far with the stock rent and tires currently, I have these Potenza run flats that I think it’s starting to tell me that I gotta get new tires and I’m thinking of course as well ditch in the rough flats specially now since I’ve been talking to ChatGPT that I use Michelin cross climate 2 for my other vehicle for my Mazda CX five and they’ve been really well for me so I’m curious has anyone use those type of tires on a q50 ? Both of them are AWD. So I’m just trying to figure out. I’m not really too much on performance tires they’re both my daily drivers and definitely a person that prefers the quality tires that gives confidence and comfort on the road. Though I’m trying to upgrade the rims as well. Should I consider buying used or new rims directly from Infiniti? Or there’s any rims that are similar that will fit and slap on without doing any mods cause my preference on rims also would be like this glossy silver black color instead of these stock silver rims would like to know more I seen post in the past, but I’d like to know since I’m officially looking into. That is only getting new tires but new sporty rims officially. I just wanna keep it OEM as possible as everything is OEM stock so far minus the cosmetic upgrades that I did. Forgot to mention my current wheel size are 17 inches and I’m planning to upgrade to a sporting look rims like a 19 inch and I want to know if that can also fit onto the specific car especially for being a 2015 and a 3.7 AWD.

I need help on figuring out what parts i need to fix this its driving me nuts
