Why "hood risers" are for ricers and actually hurt the performance of your car.

I don't know why people are concerned with IATs. If you're measuring IATs and want to decrease them, it's very simple to isolate the intake of the system without compromising airflow. Why would you want to cool the whole engine bay? Same with EGTs. EGTs come from within the engine, cooling the air around the engine will have no bearing on it whatsoever.

OK, so for driving in low-speed traffic/stop and go traffic where the fans are creating all of the needed airflow for the radiator, having no hood or hoodrisers might not matter. I guess it's not a big deal for hardparkers and pussyfooters. You could say on those cars that it doesn't really matter in the end....but what is the point in driving around with missing/misaligned body panels? To "look cool" for the latest fad? Kinda dumb if you ask me. But once you really start moving at higher speed, cooling will be compromised. Sure, with a good radiator and fans, the cooling system could probably keep up, but you're still taxing it and making it work harder. It makes little sense to make such an essential system have to work harder than it already does.

I agree, but that never stopped no one from doing their thing:
fully equipped, interfooler and all.
TO him it's worth the 2 month tire life, lol.

Haters gon' hate, ricers gon' rice

how does it make it work harder though?

cooling an engine is in the form of oil and water. which flows through the radiator, to keep it at a lower temperature.

is the argument of this thread that there needs to be a vacuum kept inside the engine bay? as long as air is passing through the radiator, the engine will cool fine. i'm not seeing how it's working any harder when the rate of air passing through the radiator (assuming that there is no blockages) is consistent while driving highway speeds.

if i drive a SR'd S13 with a FMIC, and no front bumper, i'm not seeing how it will "hurt" my performance. (engine wise) (of course it's not aerodynamically efficient)

this is speaking for regular/ average joe modded cars.

I've given an explanation that would answer your question already.
