Hello, The manifold itself doesn't need to be replaced unless there is a problem with it that's causing it to not seal such as excessive corrosion at the gasket surface. The most important thing is to thoroughly clean the gasket surfaces, use threadlocker on the bolts, and properly torque them in the correct order, otherwise it'll leak every time. The factory intake gasket set(p/n 19169127) comes with new bolts that have threadlocker applied to them from the factory and is usually the best way to go.

The torque sequence for the intake bolts are as follows.

1. Tighten the vertical lower intake manifold bolts (1) to 7 N.m (62 lb in).
2. Tighten the diagonal lower intake manifold bolts (2) to 7 N.m (62 lb in).
3. Tighten the vertical lower intake manifold bolts (1)to 13 N.m (115 lb in).
4. Tighten the diagonal lower intake manifold bolts (2) to 25 N.m (18 lb ft).
