What's the best intake manifold for an engine that only revs up to 5000 rpms?

[PKRWUD]

I would go with the RPM. The regular Performer isn't much more than an aluminum stock manifold. The RPM is designed with a higher rpm band in mind, but because it's a dual plane manifold, it doesn't give up any bottom end or off idle responsiveness. It also allows for any future mods you may decide to add.

Take care,
