Exhaust Manifold Gasket.

• Creates a seal between the engine and exhaust system
• Helps maintain pressure in your exhaust system
• Replace when worn out or leaking

The Exhaust Manifold Gasket in your INFINITI is a multi-piece gasket that seals the connection between your vehicle's engine and exhaust system When your INFINITI Exhaust Manifold Gasket is operating properly, it helps to maintain constant pressure inside the exhaust system so that engine byproduct gases are pulled away from the engine and surrounding systems.

If you hear hissing, sputtering, or tapping sounds under the hood (especially when you first start your INFINITI), an old or cracked Exhaust Manifold Gasket may be the culprit. A damaged Exhaust Manifold Gasket can cause exhaust gases to be trapped in the area beneath the front hood. As a result, these gases may reduce the engine's performance and fuel efficiency. Engine byproducts and exhaust gases are very hot, which means that a compromised seal from the Exhaust Manifold Gasket may lead to significant burns and warped parts on nearby parts in your vehicle's engine bay. In those cases, you may detect a burning plastic smell, and you could see smoke coming out of the engine bay, too.

Your INFINITI can't get you anywhere without an engine, so an old or damaged Exhaust Manifold Gasket is a problem that you shouldn't let it linger. When it comes to a replacement Exhaust Manifold Gasket, trust INFINITI Genuine Parts. Buy new parts from your vehicle's OEM for a tailor-made, reliable fit, then visit a nearby INFINITI retailer for installation and other engine care services.
