DIY Stock Intake Mod

Hi Guys,

Well, I got to thinking about the stock dual stage intake and figuring out a way to keep fender side intake opening open all the time. In case you didn't know, the fender side intake opening is closed until around 3600rpm, which is when it opens up, thus resulting in the now infamous and much beloved "IS-F Roar". As you can see from the picture below, all I did was just pull off the vacuum hose from the actuator and plug off the other end with a vacuum cap. Now the "IS-F Roar" comes on around the 2300rpm, and to me atleast, there seems to be a bit more power down low...which makes since because now the engine can breathe a bit better down low with both intake opening being open all the time. The only downside would be if this throws off the air/fuel ratio's from stock. I don't think it will drastically, but I'm not sure. Anyway, try it out and let me know what you guys think. Oh yeah, no check engine light either! Have fun...Darshana S...

Yeah teh K&N and MAF do not get along. That is why the amsoil filter was my choice. Completely dry and easy to clean. So far just turn 8K on the clock and no looking back.

Fig, can you tell me where i can get the amsoil filter?
I tried it for a day and somehow the car idled at 500 rpms as opposed to its usual 8 or 900... dunno y that was the case, i plugged it back in and the car went back to normal... does this happen with all of u?
If it's not causing you too much hassle, how bout leaving it like that for a couple of days to see if the ECU will "learn" or adapt to the new conditions, and retun to normal idle speed. hmmm...
