Has anybody got any insights into whether or not its a good idea to install a K&N 57i induction kit to my mk3 2.0L GTi 8V??
I've heard from some people its a good idea and from others that it isnt, so some clarity would be muchly appreciated 
Don't.
They just let the engine suck in lots of hot air, which reduces performance...but sounds loud.
A better option is a K&N panel filter in a modified airbox...proven to ADD power as it keeps the air cold.
But then, the airboxe soen't sound as 'fast'
