Sounds like a weird setup. The K&N doesnt come with any pipes and mounts straight onto the front of the MAF. All it does is suck in warm air.
I made a pipe that extends it all the way down to the bottom right hand side of the engine and the sound is great.
My mate had a similar 'flat' problem with his Golf GTI and it turned out to be the MAF. It might also have been killed by someone over-oiling the K&N.
If you unplug the MAF the car will stop using its 'out of range' readings and start using a default set of values. If the car feels ok then - New MAF is required.
