Stock intake modification - Toyota Yaris Forums

For my stock airbox, I did a few steps:

1. Used a dremel to cut out the mesh filter padding that is located in the top part of the airbox, and then blew out all of the residual particles with pressurized air.

2. Replaced the stock filter with a K&N replacement.

3. Opened up the driver-side fog light cover and covered it with 3 layers of screen mesh (to keep dust and debris from entering the engine bay).

4. Hacked off half of the bottom part of the snorkel, rotated it 180 degrees so that it points downward, and then attached a series of PVC piping that leads to the back of the fog light cover, so that my forward motion will aid the intake process. I superglued the snorkel into place, the PVC piping is secured by rubber couplers and the wide-mouth PVC coupler that leads into the fog light is secured by several plastic fasteners.

I've noticed a very big improvement in terms of throttle response and acceleration, especially as the weather chills up more and more. Obviously, I get the best results at night.

The only downside is that I get a little worried anytime I have to drive over 40mph in the rain...
