Your INFINITI's hardworking engine relies on an airtight vacuum seal to contain gases, and your Engine Intake Manifold Gasket is crucial for protecting your engine's seal. In your INFINITI, the intake manifold ensures that air is properly distributed equally through your engine's components as you drive. The Engine Intake Manifold Gasket (part number 140351LA0A) sits between the manifold and the engine to prevent exhaust leaks, which could reduce engine efficiency if not repaired.

The Engine Intake Manifold Gasket in your INFINITI is built to withstand many years of use, but it may need to be replaced if yours becomes worn or damaged. A cracked Engine Intake Manifold Gasket can lead to sudden misfires or reduced power, meaning your engine is likely overworking and wearing itself down if your INFINITI Engine Intake Manifold Gasket isn't creating a perfect seal. If your engine hasn't had as much “get up and go” or you've seen a decrease in gas mileage in recent weeks, you'll want to have your INFINITI engine inspected to see what condition your Engine Intake Manifold Gasket is in. We recommend visiting a local authorized INFINITI dealer or service site.

For many INFINITI models, the Engine Intake Manifold Gasket could also keep coolant inside your engine. If you see patches of green or orange liquid on your driveway underneath where you park or detect the smell of coolant (it will likely smell a bit sugary) coming from your INFINITI, the Engine Intake Manifold Gasket could be leaking. Not surprisingly, low coolant levels can lead to an overworked (and extremely hot!) engine, which can produce other more serious issues in your INFINITI engine if it's not remedied.

Your INFINITI Engine Intake Manifold Gasket is an integral engine part, and installing a new one is no easy task. As such, we recommend purchasing a replacement Engine Intake Manifold Gasket from INFINITI today, then take your INFINITI to a local dealer or authorized service center to install it. When you buy direct from INFINITI, all parts are meticulously engineered to your vehicle's precise specifications, and are backed by a 12 month/12,000 mile (whichever occurs first) limited warranty (if they are installed by a dealer at the time of your purchase).
