Check your hardware!
This picture has been branded about many times, but it's so informative it deserves its own thread.
It shows the clear sizing and subsequent flow compromises that running cheap hardware can give.
Not all silicone intake pipes are the same, the picture shows the top intake pipe (Forge) as having a clear flow advantage over the THS intake pipe (bottom) and a generic Creation Motorsport/Autobahn/ebay crap intake pipe in the middle.
There is plenty of low end torque and top end power to be had by increasing the flow in this area.
That's without mentioning the SFS Supersize K03 fitment intake pipe; which has recently seen some of the best results ever recorded on a K03 hybrid.
Wanting a bit more, or looking to maximize your current setup. Take note, don't feel left out by the K04 boys having it all their way with a Badger 5 TIP
