Because our stock manifold isn't that restrictive, I'm all for a company to build a higher flowing intake manifold but I just don't see much room for gains

These manifolds are not prone to cracking unless you have reverse detonation (read of one account), or are running more than 0.5 bar. None of which should be an issue if you're N/A.

I've read of only one cracked intake manifold here, and that was because someone didn't let the TB cleaner dry before starting up the car!
