This entire discussion has me wondering is a reverse "mod" would yield small performance improvement. Leave the flap closed all the time and always be pulling cooler air from front of car. May not be even cross-sectional area in that tubing to feed the engine though. and of course this would lose the wonderful induction sound when the flap is open.

I searched but couldn't find a video for this! I know it's super simple but for non-car people, it might feel harder than it actually is. Ended up making this video to show how easy it is.

I just unplugged the wire.... easy

I saw that as another option! Didn’t want the ecu trip out in case it required there’s a sensor or something.

Glad to hear pulling are out is just fine haha

I am curious if anyone has hooked up an ODB computer to see what the air intake temperature difference with that mod (Full open, all time) and when unmodified also when that RR CF airbox cover is on it.

I had one of these (older model) in the past and was good with that info https://www.scangauge.com/products/p...scangauge-iii/
Adding a second unit, less expensive and one I used to have, but does now have “Performance Data” https://www.scangauge.com/products/scangauge-ii/

If you’re a data nerd like I am, it’s cool. I might spring for the new one if I can find a spot for it
