Filter charger vs Intake system difference?

[chimpnumber2]

sorry for the stupid question but have been looking at getting some kind of induction kit for my mk2.5 for a while

What's the difference between the filtercharger and the induction kit?

The fitlercharger includes a cold-air intake kit, and retains most of the original plumbing. The Typhoon kit replaces the intake hose along the front.

TBH, I'd get some alloy hose, a few silicon sections and a cone filter and DIY it for a fraction of the cost of getting a K&N sticker on it. You'll 'sound' more powerful, but neither make any real significant difference.
