Hi guys.
Here's the situation. Last week, engine service light popped up on my Z while driving and felt that the Z was something wrong, so I towed my Z to a Nissan and let them investigate what was wrong. I just got called from them that they could not find what was wrong with the engine, so they decided to send my old engine to Japan and let them investigate and giving me a brand new engine.
But, here's the thing. Before my Z broke down, I was planning to mod my Z exhaust and intake. I heard that I lose my warranty if I mod my car. So I'm concerned what to do. If I do the exhaust and intake right away after I get my car back and the Z break down again, then I have to cover all the cost. Or just drive 1k miles around and do the mods after seeing there's nothing wrong with the engine.
What will you guys do, if you guys were me

P.S ahhh I have to break my engine again..................
