Please, I need some advice. I just recently purchased a 1990 GLI(2L 16valve) and I would like to make some upgrades to the engine so that I can produce more HP. I am currantly having a new transmission with modified gear ratios and an 80% locking differential as well as lightened flywheel and perfomance clutch put in. My next step was going to be a cold air intake or some kind of air induction. The problem is that I can't find anyone who makes cold air intakes for this engine. If anybody can help me with any info on this or any info on any other products that will work for my aplication and add some HP, it would be much appriciate.
