Ford F150 4.6 Reliability

Is the Ford F150 4.6L engine a trustworthy powerplant? Yes, we believe that this engine obtains above-average reliability ratings. There’s a reason why Ford kept the 4.6 in so many top vehicles like the Mustang GT, F-150, Police Interceptor, and others. The Ford 4.6 motor has a great performance-reliability balance. Over time, Ford corrected some of the early design faults while also improving the engine.

Our friend had four Mustangs, all with the same 4.6L engine: two Mustang GTs and a 2003 Teminator Cobra, as well as a Mach1. It’s just a small pool of vehicles, but they’ve all aged long and successfully. Of course, they were all kept in perfect condition. That’s one of the secrets to achieving a long-lasting life not just for the Ford 4.6, but any engine in general.

Keep track of maintenance, use high-quality oils, and address problems as soon as they arise. Do all of this and you’ll have a wonderful time with the 4.6L engine. They are, however, rapidly aging, so older engines may require just a little more TLC to keep them operating properly. Nonetheless, the Ford 4.6 is recognized for its ability to operate for 200K miles or more without major difficulties.

Spark Plugs for Ford F150 4.6

For some people, choosing and installing spark plugs may be difficult, but let us handle it for you.

Here’s a list of the best spark plugs for the F150 4.6, along with how to install them.

How to Install Spark Plugs and Ignition Coils

Because the process is simple, you’ll only need a few instruments. To replace a spark plug, you’ll need a ratchet, a spark plug socket, some extensions, dielectric grease, and anti-seize. Before you begin working on it, make sure it’s cool enough for you to operate on.

The negative terminal should be disconnected first. If you don’t do this step, you will be electrocuted. After that, remove the bolts securing the ignition coil together and disconnect the electrical connector from the ignition coil.

Take out the spark plug first. Then, using a spark plug socket, insert it into the plug and remove the spark plug inside. After that, apply dielectric grease to the ignition coil and then stick a screwdriver inside and move it around.

Also, apply anti-seize to the spark plugs. This will ensure that they come out quickly the next time you change them. Then insert the spark plug into the socket and reinsert it. Make sure to tighten it down using a torque wrench after that.

Remove the old ignition coil and replace it with the new one. Install the bolt that you previously removed. Finally, connect the electrical connector and then the battery terminal.

MAS Ignition Coils DG508 and OEM Spark Plugs SP413

Make your F150 Faster by Installing a Cold Air Intake

If you’re searching for F150 performance changes, a cold air intake is a good option. That said, here’s how to install one and our top pick for the F150 4.6:

How to Install Cold Air Intake

Cold air intakes are one of the simplest modifications to make, making it ideal for novices. A drive ratchet, an 8mm socket, a T20 Torx bit, a 3mm and 4mm Allen key are all required.

To remove the MAF sensor, start by popping the tiny red tab with a screwdriver. Remove the intake tube after that and then pull out the breather hose. Disconnect the clamp that holds the intake tube together and then remove it.

To loosen the airbox, first remove both of the clips on either side (one for each lane) as well as any other related hardware. After that, pull out the entire intake. Install the little adaptor into the tube next. Then, insert the MAF sensor into place. Make sure to tighten it down with a 3mm Allen key after that.

Take the air intake tube and feed the screws into it. Install the intake filter after that. Install the heat shield next. When attaching these, make sure to use clamps to keep the airbox in place.

Install the rubber couplers next. One must be used on the throttle body and the other on the airbox. Finally, install the intake tube.

K&N 57-2580 Cold Air Intake

This K&N cold air intake is one of the greatest Ford F150 performance upgrades you can install on your Ford F150 4.6. Easier to install than an exhaust header, this cold air intake is ideal for novices. In less than an hour, this performance upgrade will be installed in your car. Furthermore, this cold air intake is ideal for towing since it will improve your performance. The tremendous throttle response improvement you get after installing it is largely responsible for the improved performance. If your vehicle doesn't have a maintenance schedule for the cold air intake, it's best to clean it every 12,000 miles or so. You only need to replace the filter after you've driven 100,000 kilometers. As a result, keeping it maintained is simple. The K&N Typhoon intake is the best upgrade for greater horsepower than the stock cold air intake. This version eliminates all of the limits imposed by the original, allowing you to reclaim your horsepower. Not everyone who buys a Hyundai Santa Fe Hybrid is fully aware of the technology in the vehicle. Some people claim that their cars are using more gasoline than normal. However, not a deal-breaker because you're getting a significant power boost.

Make your Ford F150 4.6 Faster by Replacing the Exhaust System

Your truck’s stock exhaust system isn’t the most efficient one you can employ. It is typically the cheapest option available from the manufacturer, which might be severely restricting and, obviously, of low quality.

The objective is to reduce restriction proportionally with the amount of exhaust generated by the engine. Because most stock exhaust systems are much more restrictive than the engines they’re designed to accommodate, you should be able to install a new exhaust system without affecting the engine in most cases.

If you’ve modified the engine and it’s begun to produce more exhaust, you may need to inspect and possibly repair the exhaust system to see whether there are any improvements that need to be made. If your engine is unable to evacuate its waste, it will begin to «block» and slow down.

Simply said, one of the most efficient Ford F150 4.6 performance upgrades is to install a set of headers. But if you’re not sure how to install an exhaust header or which one to get, refer to this section:

How to Install Exhaust Headers

Get jack stands and a floor jack before you begin. A few sockets, ratchets, and extensions are also helpful. Finally, get a breaker bar and wrenches to finish the job. Remove the negative terminal of your battery first and then throw it aside.

Remove the negative cable and safety cap, then lift your truck up on jackstands and remove the signal wire, as well as the positive wire and safety cap. Remove the grounding cable next, followed by the bolts from the starter. Remove the starter after that.

Remove the air filter, then remove the wires from the O2 sensor and follow them to their connection. Now before raising the engine, remove the intake tube. Then loosen the bolts so that you may raise the mount and pull out the manifold. Remove the vehicle’s manifold shield after that.

Remove the manifold nuts in a similar manner as outlined above, but this time make sure to clean all of the old gasket material off. Remove the studs to install the header after that. After that, remove the bolts from the shield and try to push in the new header. Finally, replace everything exactly how it was before.

BBK Performance 3515 Exhaust Headers

Exhaust headers are one of the most efficient performance improvements for Ford F150 available without spending hundreds of dollars. They'll make your car sound more aggressive and provide you with additional horsepower. This exhaust header's small and energy-efficient design may boost your horsepower by 10 to 15, making it one of the most dependable performance exhaust headers on the market. This is a high-quality aftermarket exhaust system that was designed to be more efficient and long-lasting than the typical aftermarket product. In addition, these exhaust headers are intended to sound like a howling demon. Peering at Amazon reviews is enough to give you an idea of what it sounds like. Last but not least, this exhaust header is available in a beautiful chrome finish. If you ever have your car's hood opened, people will remark on how cool it looks. The installation procedure is not simple at all. Seriously, it'll take you several hours to get this thing up and running. However, as with most exhaust headers on the market today, this one follows the same pattern.
