Spotted the Dbilas Flowmaster kits on their web site the other day so figured I might sus out their Z22SE application. My intention was to investigate a true performance filter option with a CAI as my BMC CDA is sweet but due to the nature of the Z22SE airbox I cant get outside air into the filter without major modification.
Here's the info that I've been provided by Dbilas...
thanks a lot for your interest in our products.
For the Opel Astra G with the Z22SE engine we have a sport filter "FlowMaster" in our program.
The kit contains the FlowMaster air filter box with filter cartridge, hoses and necessary holders.
The price for the sport filter is € 199,-- incl. 16 % VAT.
Additional we could offer an air inlet dukt "FlowPipe" for € 110,20 incl. 16 % VAT.
The air inlet dukt fit with the original air filter box or with the FlowMaster.
Advantages of the both parts:
more fresh air = - less consumption
- better torque
- super sound
Attention! If you order FlowMaster-System and FlowPipe you save 10 %.
Please find enclosed a picture of the FlowMaster which is fitting in the Astra G Z22SE engine.
For further questions do not hesitate to contact us.

I think these would beat the BMC CDA for application/installation on the 2.2 at least. However I would be interested to get some figures for sound and performance variances.
