Hi. I just bought a new GranSport and I take delivery of it next week. I want to upgrade the air filter/intake just to get a little more power because it is a pretty easy and cheap mod. The only company I could find that lists air filters for our cars is a company called BCM. They list 5 different options for this engine. I want to contact them, but they are an Italian company and I can't find a phone number on their website. I live in America so it makes it hard to contact them. Anyways, I was wondering if anyone on this forum has a BCM filter and knows which one is best or if there is another alternative that is better. I did a search under BCM and air filters on this site and didn't find anything. Their web site is bcmairfilters.com if anyone wants to check them out. Thanks.
