I would have to disagree with you guys on this one, well partially for some cars. I use to have a 2000 Mitsubishi Galant and I put a cheap intake from ebay on it and since it was made crappy with no good braces to support it well it wound up cracking my intake manifold. So I got it fixed thought I had it supported really good even had my mechanic help me support it and it still wabbled too much and I had to replace the mnifold again so I went back stock. So I would deff go with a good quality one such as AEM so it has proper support brackets built on.
