Well a massive thanks to Ecky for gving me his Vec B airbox to try and make a enclosure but even with chopping it up i dont think it would have fitted right in the astra.
I didnt really want to chop the Astra airbox up.
I then fitted but was a bit disapointed with the fitting as i had to make the oval inlet pipe fit the round neck of the inuction kit, the noise was good though lol. I am going to try and Vec inlet pipe and see if thats better fit with it been round.
I will post pics when i am happy.
