Right here is the time for all the silly questions, unfotunatly (well not unfortunatly for me, just for you lot) I have spent the last 3 years of car ownership with SEATS, so I know a fair bit about them. But hardly anything about the Astra's.
I have just bought myself a shiny silver 2001 Astra Coupe Bertone, the 1.8 16v. I was thinking about either removing that great big air box and replacing it with either a cone or something like that, or just getting a good panel filter.
Just need a bit of advice with what will work best with that engine.
