Now I have done a bit of research and I thought you guys might be able to help.
i have heard that the 325 manifold has a much wider air intake than the standard 328 one and that if I replaced my manifold with this, I could increase my BHP by up to 30.
Is this true? If so does anyone know where i can get a 325 manifold from, how much and are there any other parts that need to come with it.?
I saw one on ebay a while back for £80 was this a good price?
