Congrats on the new purchase. Make sure your air filter is secured on there. Judging from the picture below, it looks like the air filter is not sitting perfectly even on the aluminum "venturi ring" that it clamps to. Same thing happened to my intake a couple years back, and after time it worked its way off and one day I popped my hood to find my air filter just sitting in the engine bay, with nothing between the dirty air and my MAF sensor and thottle body! So anyway, just make sure it's on there properly.




Also as others have mentioned check your oil level periodically as the "rev-up" engine in the 2006 Z's are notorious for consuming oil excessively. I have a feeling mine does it, especially because I can smell oil burning when I get around WOT, but I get my oil changed every 3k miles or so and haven't had a problem yet.

 

Very nice Z and welcome to the community. Previous owner picked some pretty good mods. Popcharger is a classic around here. Those are indeed good brakes, and with the strut bar as well its a safe bet that she's probably seen some track time (as others have said.) Don't let her down. Go hit the track!!
