DIY additional airflow

[dj92]

Of almost no avail, far too long and far too small in diameter.
I've tried a quite short and straight one (went directly to a hole next to the radiator) with a diameter even slightly bigger than that of the intake last summer and the engine lost a lot of power, I had a hard time getting over 130km/h.
I think this happened because it was a textile one with a fuzzy surface.
I'm still looking for one with a smooth surface, as soon as I have new results, I'll inform you ;)

I have to agree. Here's a video that might be of interest to you:

Quite interesting, I've been looking for something like this for a long time, thanks a lot!
At least the 1KR-FE has a throttle body heater that uses the engine coolant.
Blocking this might decrease the intake temperature (being not aware of this, I wondered how it could rise to up to iirc 65°C last summer).

However, I rather hope for the ram air effect in order to get past the 160km/h barrier on the autobahn ;)

Agreed, you may get just a little more colder air going to the airbox entrance, but I honestly don't think it's enough to make a noticeable difference, ESPECIALLY with the rough surface of the split loom tubing.


The only scientific way to test this mod is to do back to back tests monitoring the Intake Air Temperature sensor.
