Well I have a 13' gen coupe(14' newface).if you mean their similar by the vents than you're wrong!the hood vents on my car are plastic and no function just a silly accessory lol.they only thing these two have in common is that their both cars and their both have 2 doors!

That said, why cannot GM make a similar setup for the 6th Gen? Look at the upper left in the SLP graphic, note how straight through the air path is?! WHY would GM do all these curves on the 5th & 6th Gen air intakes? MAKES NO SENSE TO ME!

Noise reduction. At least that is what I have long thought. Even with all those twists and turns, it is likely a true cold air intake. A much quieter intake than the short ram intakes the after market prefers, but also much more restrictive.

NOBODY buys a Camaro and worries about the volume/decibel level of air going into their engine! Ridiculous! After removing the sound reduction claptrap GM installed on both my Camaros, I can honestly say it made no perceptible differences between sound!

So any other explanations?

I just need to say that this is one of the most informative threads I've read on this site in a long time. Lots of really good points being made, including how the position of the hood scoop can dramatically affect whether there's any actual net gain in airflow.

I'm on the fence between ordering a Z-Force hood, which I now understand is cosmetic now obviously based on the position of the scoop, or a functional cowl induction hood. Lots of things on my car are totally for show, so I may still bite the bullet and go for the former. I am slowly killing the performance and MPG of my car in the process, but it looks good, lol.

The only system that worked was the Chevy cowl induction because of negative air pressure at the base of the windshield. That's why NASCAR takes the air from there in its intake systems. All scoops on the hood do is create turbulence and create drag. As an air extractor they work perfectly, removing the heat and air pressure from under the hood. keeping them flat on the hood does not create drag so there efficient.

Although the Cowl Induction hood was less aggressive looking than some of those from Ford and the MOPAR brands it was just as effective, maybe more. Drag racers use different types of ram air scoops but I believe they also do not use air filters that would greatly reduce the effectiveness of a ram air effect.

150mph+ gives most intakes ram air effect

you drive a hyundai though..

I saw a video testing the new GT3 RS and they noted that the new air inlets in front of the rear wheels added 10HP to the engine when the car was at speed, so I guess Porsche have a way of using ram air to increase power in a modern engine.

I agree, the characteristic is known as the "aerodynamic boundary layer", i.e. the air at the surface of the car is fairly static and not moving. That is why the real performance driven people in Pro-Stock NHRA (who have access to wind tunnels to test) have those huge air scoops that stick way up above the stagnate air on the surface in order to be meaningfully effective. Back in the day the Chevy engineers designed a system (cowl induction) that actually had some benefit over something that only looked good.

Hood scoops help everything!

sorry but thats not true 100% my LS1 worked so much better with the Ultra Z hood and a volant air intake I can fell how the car can breath much more easy and it also feels a way more dynamic going on the highway and Im not going 200 MPH lol

The Ultra Z hood is useless and even restrictive if not used right, they need special air lids in order to be functional... like the volant air box, it aislate the airfilter from the heat and get a direct shot of cold air from outside, works even better when using a FI like a supercharger


pic not mine nor my car
