Renntech carbon fiber airbox - 3rd independent dyno
I have a few questions:
1. Can you feel the power gain while driving or not?
2. What about the noise of the engine?
3. Is it easy to install and then put back the original filter.
Thanks so much.




I have a few questions:
1. Can you feel the power gain while driving or not?
No, not that I can notice…….but would you really notice it on a 362 HP/376 TQ engine?
2. What about the noise of the engine?
From inside the car it sounds pretty much the same..
3. Is it easy to install and then put back the original filter.
The actual airbox? It can be tricky until you get the hang of it. Basically there are 4 clips on the airbox and 4 rubber knobs on the engine. You have to align the airbox over top of the rubber knobs and press down on the airbox. Also, you have to make sure the back part of the airbox (over the MAF) is pressed all the way down. When you think it is, press down on it again! A well lit work area or trouble light is your best friend here. I’ve often felt I was going to break something when I was taking it off or putting it on but everything is pretty robust…
