Exposing that aluminum intake manifold to direct contact with exhaust gas is a really bad idea. Ther's an alternative method to get exhaust heat into that area, but that kit would be the absolute last option I would consider. Send me a private message for a phone number, and I'll describe a much more effective and safer method. It's a bit too involved to discuss with a series of forum entries.
