The steps that come before it require no errors when fitting an intake manifold and an engine, starting from the very first step, right until the last step. The first step involves taking off the previous one by dismantling a few hoses, bolts and removing the sensors. In scrubbing surfaces after removing the manifold guarantees a better sealing outcome, attention to detail is very much required. While fastening the new manifold with the correct bolts, attention not to cross thread while applying the correct closing torque is vital as well. Care while applying torque is extremely crucial for tools that are not specifically set, and calibrated example, when properly set bolts are used. At the intake manifold’s bottom side, along the mounting surface it will meet the cylinder head, an intake gasket is to be put in place. Every hose, bolt and gasket is to be set as well showing that achieving proper placement of the intake manifold therefore averts any abnormal gas or vacuum fume leakage to boost engine performance.
