HKS Intake Duct V2: yes or no?
I searched around a lot, but I didn't fint an answer: is this part effective for performance in a NA car or not?

im sure someone, somewhere made 3 more horsepower with one, but thats not really the value of in intake in my mind. theyre cool engine dressup, you get to display a great brand like HKS, and have fun turning wrenches.

I have the Greddy one that picks up air from the bumper opening. It keeps intake temps surprisingly low when the car is moving.

I’d like to know too. One would think it would be worse than oem because it deletes all of those factory airflow resonators that keep the flow rate as high as possible. But some people have reported an increase in throttle response with units like the HKS, and even OFT has recommended the snorkel mod where you heat up a pre-cut OEM duct and stick the bottom 2 liter coke bottle into the opening so the opening becomes more like a circle.
Just so damn expensive for the Japanese name brands! |

I meant more along the lines of somebody producing their own version of it. Maybe using the HKS as the base, and then making mild design changes. Would be really cool if somebody made something more similar to the GReddy one.

The problem with all those designs and factory “cai” is you have no airflow coming in from front bumper it’s just pulling whatever random stagnant air in that area. Front crash bar and foam block all air from that side so have small holes on the back of the plastic piece behind intake.
Beatrush bumper bar completely opens up all that airflow to be able to actually pickup moving cold air from the front end. |

There are several air scoops available that solve this. Greddy pictured, AutoFactory, LegSport.. I can't say that it added any power even on the butt dyno. But the IAT we lower so thats nice. |

I think even BMW switched it up from a ram air style intake to drawing from behind the bumper like our cars do. |

Velocity through the filter is pretty low. Only way in increase that is with a pressure difference. Airflow has a dynamic pressure in addition to a static pressure. When you slow that airflow down (with the radiator) you transfer that dynamic pressure into greater static pressure, which in the twins is captured in the grill opening. That static pressure is reduced less by changes in flow direction than dynamic pressure, and also suffers from less turbulence. As such, using the static pressure from the grill opening is theoretically more efficient in producing clean, high pressure airflow than a direct duct to the front of the car.

OK, this is all true if talking of ram air intakes, but HKS duct is not affected by speed velocity, as it stays behind the bumper. So, no CAI, loss of resonators, shorter and larger, air temperature is colder?

Oh! This just replaces the factory "snorkel" with a shorter piece and larger opening? I imagine it will change the sound but not have much more effect if you keep the intake baffle underneath it.
