What is a good website for Ford Focus modification info with video reviews?

There are a couple interesting "mods" that I've found that make driving a Focus a bit more fun. However, a lot of these mods don't have decent review videos for me to see how they change sound, performance, etc (I have already tried YouTube). The video in particular that I'm trying to find right now is a one that shows how removing the air box from the Focus affects the sound of the car from outside of the vehicle while it is accelerating. Any decent source for info and reviews will be appreciated though.

So why as all cold air does is make a car engine more difficult to start from cold. That is fact number 1. Then we have the extra fuel it will suck in and not burn. Yes it does not burn all it sucks in. Fact 2. Then we have the next idiot thing removal of the exhaust pipe system. This reduces the back pressure which aids the engine cope with going up hill. And slowing down the engine down hill. Along with beer fuel consumption. Fact 3. Then we come to why the simple fact is when racing a car around a race track the rev's never go below 4000 rpm when out on a highway or in town it needs those low RPM's to get away and fast as well all gone when the car makes extra noise. Lack of acceleration and lack of top speed. The town is not a race track the noise is not what will help infact it lands you in court or fined so much and the car gets crushed.

It'll be somewhat louder. The reason being that the OEM intake is built to cancel out certain resonance frequencies so that it's quiet for the people in the car. Designers of aftermarket intakes don't bother with that because they know that people who buy these things *want* to hear more noise. Unless you have an ST or RS, there's not going to be a lot modification videos out there, as the base Focus isn't really a enthusiast's car with a huge following in the US
