FAQ

Q: Is there a difference in intake heights?
A: Yes. Select the correct intake for your vehicle, and check your vehicle's hood clearance before selecting a high rise intake.

Q: Can intake bolts be overtightened?
A: Yes. Tighten the intake bolts to manufacturer's specifications. See the engine service manual for torque specifications and sequence.

Q: Can a leaking intake gasket cause an engine miss?
A: Yes. It could suck additional air into the cylinder, which will cause less efficient combustion.

Q: Are there signs that there may be a problem with a vehicle's intake?
A: Yes. Reduced engine power and abnormal sounds or vibrations are signs that there may be a problem with a vehicle's intake. Engine oil and/or coolant leaks/consumption can also be signs of an intake issue.

Maintenance & Troubleshooting

Signs of Wear & Troubleshooting

Signs of wear for engine intake manifolds include but are not limited to:

Oil or coolant leaking at the top of the engine
Poor engine performance
Hissing or whistling sound at the intake manifold
Reduced engine power
Unusual odors while the engine is operating
Visible vapor from the engine compartment
Fluid level loss or coolant mixing with engine oil

Good Maintenance Practices

Before purchasing and installing an engine intake manifold, make sure it is the correct size and fit for your vehicle.
Keep the air duct assembly clean and properly sealed and the engine air filter clean or changed at every oil change, or more frequently if the vehicle is operated in dusty environments.
Tighten the intake bolts to the proper manufacturer's specifications, and do not overtighten.
Refer to the engine service manual for proper torque specifications.
Clean the engine's exterior as needed - buildup of oil and dirt can cause the engine to run hot or hide leaks.
Have your vehicle inspected as soon as possible if the ‘Service Engine Soon' light illuminates.
Have your vehicle inspected immediately if the ‘Service Engine Soon' light flashes rapidly, as this could indicate an engine misfire condition which may damage your engine and/or engine emission components.
Do not run an overheated engine, or damage to components or gaskets could occur.
Regularly inspect engine intake manifolds for signs of damage or wear, and replace them if signs of damage are found.
