aftermarket intake experience

Rooskey

This car has two throttle bodies and only six cylinders so getting the air in is not that big of a deal. My tuner (also the tuner and car builder of the ceo of Zdayz) says its more about the exhaust than the intake. With the power he has got out of our cars ill trust him on that point. I have raced many 370's with other intakes and never have lost one due to my intake choice. The k&n set up is a good product and delievers a broader torque and hp range than most others. If your looking for peak hp numbers on a dyno than yes get a good longtube setup. If your looking for good torque and acceleration out of the corners then the K&N is hard to beat. Just my experience.

Sucking in extremely hot air is not as beneficial as sucking in much colder air. Maybe within the first couple of minutes of driving it's the same but that's it. The Z seems to get really hot under the hood.

What is "extremely hot air"? How much colder is the "much colder air" vs the "extremely hot air"? Has anyone actually measured the IAT of a long tube setup vs the K&N?

If its 80 90 100 degrees out side can you imagine how hot it is under the hood? That's extremely hot! VS the temp of the air that is outside the engine bay.

Yes I can imagine. But imagining something and having actual facts to back up my claims are 2 different things. You may be right. But then again, how would we know?

Yes the engine bay is hot when you open the hood. But the car is standing still. When the car is moving there might be plenty of cool air getting to the air filters. Unless you actually measure the IAT (while the vehicle is moving) and can say with certainty that one design makes a difference over another, we are all just "guessing".
