The procedure starts by removing the brace bolts (1 and 2 from the Intake Manifold brace and then the brace and upper Intake Manifold while keeping the fuel pipes and hoses uninjured. First disconnect Ignition Coil electrical connectors and Ignition Coil bolts before removing the ignition coils. Installation begins with placing ignition coils before using Ignition Coil bolts to secure them at a torque setting of 10 N.m (89 lb in) while reconnecting the Ignition Coil electrical connectors. Follow Intake Manifold reinstallation with the engine cover installation.
