The 2014 Chevy Spark intake manifold torque sequence and torque specs depend on the engine type. Here are the torque specs and sequence for each engine type:
1.0L Engine:
Step 1: Tighten the bolts to 44 inch-pounds (5 Nm).
Step 2: Tighten the bolts to 89 inch-pounds (10 Nm).
Step 1: Tighten the bolts to 44 inch-pounds (5 Nm).
Step 2: Tighten the bolts to 89 inch-pounds (10 Nm).
Step 3: Tighten the bolts to 18 lb-ft (25 Nm).
Torque sequence: 8 4 1 5 9 7 3 2 6 10
It's important to follow the torque sequence and torque specs carefully to ensure that the intake manifold is properly secured and sealed. Over-tightening or under-tightening the bolts can cause leaks or damage to the engine.

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use after-market performance bolts like ARP's, you should follow the recommended torque specifications.
