A Ford Fusion Owner's Guide to the Engine Intake Manifold Gasket Set (2006-2020)
Fixing rough idles, vacuum leaks, and Check Engine Lights in your Fusion often starts with the right intake manifold gasket.
- The most common sign of a bad intake gasket on a Fusion is a vacuum leak causing a rough idle and lean codes (P0171/P0174).
- Always verify your exact engine size (e.g., 2.5L, 3.0L, 2.0L EcoBoost) before ordering, as gaskets are not interchangeable.
- While the manifold is off, it is highly recommended to also replace the PCV valve, which is often located underneath it.
- On 2014-2017 1.5L EcoBoost models, check for TSB 17-0028 regarding a loose manifold bolt causing coolant leaks before assuming a simple gasket failure.
Is Your Ford Fusion's Intake Manifold Gasket Failing?
A bad intake manifold gasket is a common issue that can cause a range of frustrating engine problems. The failure is usually due to the constant expansion and contraction from engine heat, which can cause the gasket material to become hard, brittle, and cracked over time. The most common failure is a vacuum leak, which allows extra air into the engine that the computer doesn't know about.
Choosing the Right Aftermarket Gasket Set
When replacing the intake manifold gasket, you don't have to buy an expensive OEM part from the dealer. Quality aftermarket brands offer reliable seals, often at a much better price. The key is to choose a brand known for using durable materials that can withstand modern engine temperatures and fluids.
- Reinz (Victor Reinz): Often considered a top-tier aftermarket brand, Reinz is an OEM supplier for many European car manufacturers. Their gaskets are known for using soft, pliable rubber compounds that seal well, even on surfaces that aren't perfectly flat. This is a great choice if you want OEM-level quality and peace of mind.
- Apex: Generally viewed as a reliable budget-friendly option. While sometimes associated with overseas manufacturing, user feedback is often positive. For a daily driver, an Apex gasket set can provide a perfectly adequate seal and restore engine performance without the higher cost.
Pro Tip: Many Ford Fusion engines, like the 2.5L, have the PCV valve located under the intake manifold. Since you have to remove the manifold to replace the gasket anyway, it's a perfect time to replace the PCV valve and its related hoses. These parts are inexpensive and can prevent future oil consumption or leak issues.

While there are no widespread recalls specifically for the intake manifold gasket itself across the entire 2006-2020 range, some related issues and Technical Service Bulletins (TSBs) are worth noting:
- 1.5L EcoBoost (2014-2017): TSB 17-0028 was issued for a condition where an intake manifold bolt could back out, causing damage to the charge air cooler (CAC) and leading to coolant loss and white smoke. Symptoms included a low coolant level and multiple engine codes like P0300 (misfire) and P0217 (engine overheat). The fix involves replacing the intake manifold and CAC assembly.
- 3.0L V6 Engines: These engines are known to develop vacuum leaks around the intake area, which can cause lean codes (P0171, P0174), a rough idle, and a hissing sound.

Frequently Asked Questions
Do I need upper and lower gaskets?
It depends on your engine. V6 engines like the 3.0L and 3.5L have a two-piece intake manifold with an upper section (plenum) and a lower section. In these cases, you will need both upper and lower gasket sets. Most 4-cylinder engines have a single-piece manifold and only require one set of gaskets. Always verify your specific engine's needs before ordering.
Should I use sealant on the new gaskets?
No. Modern molded rubber gaskets are designed to be installed dry. Applying RTV sealant or any other chemical can interfere with the seal and may even cause parts of the gasket to break down prematurely. Simply ensure the mating surfaces on the cylinder head and manifold are perfectly clean and dry before installation.
Is this a good DIY job for a beginner?
This job is moderately difficult. For a 4-cylinder engine, it is more approachable for a DIYer with some experience. For V6 engines, the process is more involved due to the two-piece manifold and tighter access. You will need a good socket set, a torque wrench, and patience to disconnect various hoses and electrical connectors. If you are not comfortable, it's best to leave this job to a professional.
🎬 See this walkthrough for removing the V6 intake manifold.What are the most common mistake when ordering this part?
The most common mistake is ordering a gasket set for the wrong engine. The Ford Fusion was available with several different engines over its lifespan (2.3L, 2.5L, 3.0L, 3.5L, 1.5L EcoBoost, 1.6L EcoBoost, 2.0L EcoBoost). The gaskets are not interchangeable. Always use your vehicle's VIN or specific engine details (e.g., "2.5L 4-Cylinder") to confirm you are buying the correct part.
