2007 Focus LS airbox/intake project

[trenchtractor]

Jane has started whining about the price of fuel. So it's time for me to start searching for better fuel economy. lol.

One of my favourite mods to a bike is to cut the intake side of the airbox wide open and use a better flowing filter. It's been my experience that BMC is the best but my brother works for a parts shop, so K&N is usually what he can get me cheap.

In the case of jane's LS, I want to make sure the car looks stock during cursory inspection. I would love to open a massive hole in the bottom of the airbox, but I'm still undecided about the best way to get fresh clean air in.

This thread is a place for me to dump photo's, ideas, thoughts and eventually a final outcome.
