Are you considering replacing the intake manifold on your 2003 Lincoln Town Car and wondering about aftermarket options? Specifically, you might be asking: will a Ford Racing intake manifold, like part number M-9424-P46, work for your 4.6L engine? Let’s dive into the compatibility and what you need to know about this essential Intake Car Part upgrade.
Ford Racing Intake Manifold M-9424-P46: A Direct Fit for Your 2003 Town Car
Good news for Town Car owners! The Ford Racing M-9424-P46 intake manifold is indeed compatible with your 2003 Lincoln Town Car’s 4.6L engine. This model year comes equipped with PI (Performance Improved) heads, which makes it a direct fit for this performance-oriented intake manifold. This is a significant upgrade over some aftermarket intakes, particularly Dorman manifolds designed for non-PI engines, which can actually lead to a decrease in performance for PI engines.

Essential Replacements When Upgrading Your Intake Manifold
Replacing your intake manifold is a significant job, and while you’re at it, it’s wise to replace other wear-and-tear parts. Here’s a list of components you should consider replacing to ensure the longevity and reliability of your engine:
- Intake Manifold Gaskets: Always replace the gaskets when installing a new intake manifold. OEM Motorcraft gaskets are highly recommended for their quality and perfect fit.
- Spark Plugs: With the intake manifold removed, spark plug replacement becomes much easier. It’s a good opportunity to install fresh plugs.
- Thermostat: The thermostat is relatively inexpensive and is easily accessible during this job. Replacing it proactively can prevent future cooling system issues.
- Water Pump: If your Town Car has around 100,000 miles or more, consider replacing the water pump. A failure-prone component, replacing it now can save you from potential breakdowns later. OEM Ford water pumps are a reliable choice.
- Radiator Flush: A coolant flush is recommended when replacing the water pump to ensure the entire cooling system is in good condition.
- Injector O-rings: While optional, replacing the injector O-rings is a preventative measure that some mechanics recommend to avoid potential leaks.
- Metal Coolant Pipe: Crucially, replace the metal coolant pipe located beneath the intake manifold. This pipe is prone to corrosion and is much easier to access and replace when the manifold is off.
