I've put on a Pipercross Venom a few days ago and very very impressed with the kit, not had chance to log the peak g/s yet but throttle response feels much better compared to std airbox and less lag.
Had a good 2 hour drive today (an hour of that stuck in road works) and the filter housing was still cold afterwards, MPG has increased slightly and holding 17-18psi before was just about seeing 16psi with smoothed airbox, additional 3" air feed from lower bumper and a K&N panel filter.

Used to have a big Jetex cone on a while back with an air feed and while it sounded awesome there was defiantly a noticeable hesitation before the turbo kicked in. Did some logging and got same peak g/s figures of 186.96 with the Jetex and a CAI with Apexi filter on an hour before but felt better with the CAI on.
5th air filter setup this is now and providing peak figures are decent and can cope with the planned K04-001 will not be changing anytime soon.
