I fitted my Forge twin take air filters on Sunday last. The installation went well, except for removal of the clip at the turbo inlet pipe and the 24mm rubber screws for the heat shield to be installed. Driving around is so much nicer (partly because I did the fuel line mod at the same time - so no more rattles!), throttle response is much smoother and power delivery better! I am getting used to the noise, although initially I did feel it a little intrusive!
My mpg has gone up by at least 4-5 mpg which is an added bonus! The driving experience is so much nicer, I would definitely recommend this to anyone thinking of getting an upgraded air intake kit!
