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

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.
