Hi everyone, just wanted to share my latest mod. Stock intake with a Green filter. It normally comes dyed in green color (hence the name). I attached it to the stock pipe using a universal reducer. I just had to smooth out some edges on that piece as they were rough and added heatshrink to make a tight connection. The reason I wanted to use my stock intake was to eliminate or reduce the vacuum cleaner noise associated with aluminum tubing. The stock rubber pipe has many ridges by design, so the noise is cut by about 50% vs. metal pipe. Before this I ran a K&N drop-in filter with a modified factory box, so the sound was already better than stock. But I wanted to get more out of it and possibly hear the turbo spool. Having tried regular cone filters before I knew I had to go with something even more open, so the dual cone design was my pick. Having run that filter on my fiesta it was the only one I heard the spool with.
You can see from the video, on cold start (early morning) it still sounds fairly quiet. Overall, I am very happy with the sound. Having tried a few different setups I can say this is so far exactly what I wanted out of an intake. It's quiet enough to be subtle on the street, yet loud enough to be fun once some throttle is applied. There is that loud and deep psshhhh sound and you can hear the turbo spool in every gear (not as pronounced as on the fiesta, but more so than a regular cone filter due to open front cap). This is a fairly inexpensive mod and allows for all the factory hoses to remain plugged in. Perfect alternative for anyone like myself who is concerned with noise.
Filter name: Green Filter 2896 3.5x6.5 dual cone.
The inside diameter of factory pipe is 3.25"
Filter inside diameter is 3.5"
