The Best V8 Stories One Small Block at Time
The reason most people don't buy aluminum intakes is because so many people are scared of something they are not educated about, heatsoak. more people talk about it that have never even owned a aluminum intake than anything. Tuners don't like then b/c some people can get them installed correctly without vacuum leaks.
I have seen plenty of cars with aluminum intakes without have a single issue. Plus if your that worried about it while at the track you can toss a ice bag on it, but I wouldn't bother.

You are right on the money. I have a alluminum intake on my car. It spent hours on a dyno with no cool down time. No signs of lost power due to heat soak
