I am looking to add a little capacity to my small sump for my 99 VW Passat 1.8T. I have heard there might be a larger filter that fits the engine. Is this a good idea? Or is it better to stick with the stock Mann filter. Any recommendations on filters?
I also have heard that the stock filter has a check valve which protects the turbo somehow??? Can anyone "school me" on this??
