This is for those people who will have their cars stored all winter and don't mind pulling parts off. The deal is: if you send me your intake manifold, I will return it to you polished for free. I will even do your valve cover if you're interested. Throttle body will cost ya through. I want to do mine, but I don't have a second car, so I need cores, that's why I will do the work for free. Email me if interested email@example.com
Here are some pictures of the polishing I did on my bike for an example of my work.
