No way.
The K&N didn't save you 25% in fuel economy. Your old filter must have been clogged so bad it was choking the engine.
Any improvement claimed must be due to other changes such as plug, leads, pumping up the tyres, better quality fuel, accurate fuel pump reading or bad maths in calculating the original fuel economy etc. The 25% improvement claim over the ADR fuel economy test, NO Way, or Holden would install K&N filters at the factory.
A brand new OEM filter would have done the same thing as the new K&N.
K&N filters are for racing not for street use. Its been discussed too many times on BITOG oil site. All the K&N does is allows extra dirt into the engine and requires the engine oil to be changed earlier.
On the VS or VX just drill a 3" (76mm) diameter hole in the lower air box behind the headlight area,
1. this will allow it to breathe better and its fully legal
2. will also improve throttle response ie quicker revving.
3. slightly quicker off the mark
4. you don't need the 2nd snorkel for cold air pickup for street driving(This is a ...ank factor only IMO).
5. you wont pickup water as some 2nd cold air intake snorkels can do
6. retains factory setup and factory look
It doesn't increase total power though.
Making this change removes any restriction there is across the air box / intake.
I recall on the other commodore website a member changed their Cold Intake setup as it affected the fuel economy due to the air being too cold and dense. In that case the member claimed it improved 2L/100 after the 2nd and 3rd cold air in takes were removed.
