Best Spark Plugs for Ford F150 4.6

Choosing and installing spark plugs can be challenging for some folks, but let us do all the work for you.

Below, you’ll find our favorite spark plugs for the F150 4.6 and how you can install them.

How to Install Spark Plugs & Ignition Coils

You don’t need many tools for this job since it’s pretty simple. To install a spark plug, get a ratchet, a spark plug socket, a few extensions, dielectric grease, and anti-seize. That said, make sure you’re working on a cool engine.

Next up, disconnect the negative terminal before getting started. Do not skip this step, or you might get electrocuted.

After that, disconnect the electrical connector from the ignition coil and then remove the bolts holding the ignition coil together.

Now grab your spark plug socket and put it inside the plug, and then remove the spark plug inside.

Once that’s done, put some dielectric grease on the ignition coil and then shove a screwdriver inside and move it around.

Additionally, put some anti-seize on the spark plugs. That way, they’ll come out quickly next time you replace them.

Next, load the spark plug into the socket and then put it back in. Make sure to tighten it down using a torque wrench.

With that out of the way, install the new ignition coil and install the bolt you removed earlier. Finally, plug the electrical connector and then the battery terminal.

Cold Air Intake Kit for Ford F150 4.6

If you are looking for Ford F150 performance upgrades, then consider getting a cold air intake. That said, here’s how to install one and our top pick for the F150 4.6:

How to Install Cold Air Intake

Installing cold air intake is one of the easiest jobs out there, making it perfect for beginners. That said, you’ll need a drive ratchet, an 8mm socket, a T20 Torx bit, a 3mm and 4mm Allen key.

The first thing you have to do is unplug the MAF sensor. To do this, pop the little red tab using a screwdriver.

After that, pull out the MAF sensor. With that out of the way, disconnect the clamp holding the intake tube together and then pop the breather hose.

Once that’s done, proceed to pop off the top of the airbox by releasing the little tabs. Next up, pull out the entire intake.

Next up, install the little adapter into the tube. After that, put the MAF sensor in place. Make sure to tighten it down using the 3mm Allen key.

Now grab the intake tube, hold it against the adapter for the air filter, and then feed the screws. Building upon that, install the intake filter.

Now install the heat shield. When doing this, make sure to attach the clamps to secure the airbox.

Next up, install the rubber couplers. One must be installed on the throttle body and the other one on the airbox. After that, put the intake tube in place.

Finally, install the extension for the MAF sensor and then plug the breather hose. Need help setting it up? Then watch this video:

to make more power. But if you’re not sure how to install an exhaust header or choose one, then check this section:

How to Install Exhaust Headers

Before getting started, get jack stands and a floor jack. You also want to grab a bunch of sockets, ratchets, and extensions. Finally, get a breaker bar and wrenches.

Start by unplugging the negative terminal of your battery and then throw it aside.

Next, jack up your truck, put it on jack stands, and then remove the signal cable, the positive wire, and the safety cap.

Next, unplug the ground cable and then take off the bolts from the starter. With that out of the way, remove the starter.

From there, head over to the driver’s side of the transmission and then remove the O2 sensor and the wires.

Now before raising the engine, remove the intake tube. After that, loosen the bolts so that you can raise the mount and then pull out the manifold.

Once that’s done, take off the shield from the vehicle’s manifold.

That said, proceed to remove all the manifold nuts. With that out of the way, remove the studs to install the header.

From there, remove the bolts from the shield and then try to squeeze the new header in. Finally, put everything back on.

Other Performance Upgrades to Consider

All the Ford F150 performance parts we covered above are good enough for most drivers but if you still need more horsepower, then make sure to check these mind-blogging upgrades for the F150:

Diablo Tuner

If there’s anything car enthusiasts love, that’d be a Diablo tuner. This is one of the easiest, although expensive, ways to get more horsepower.

In fact, it’ll make a more significant impact than installing an intake and exhaust.

Cat-Back Exhaust

Installing a cat-back exhaust is more complicated than installing a Diablo tuner, but you’ll be glad you took the time to do so.

So why install one? A cat-back exhaust is an excellent way to increase your exhaust noise — the sound is not as loud as you’d think, but it’s more aggressive than the stock.

Finally, the cat-back exhaust will increase your horsepower. All things considered, it’s an excellent upgrade.

High-performance Intercooler

Another excellent upgrade to increase your horsepower is a performance-oriented intercooler.

However, keep in mind that you won’t notice that much of a difference if you haven’t installed other mods on your vehicle.

Bigger Throttle Body

Why stop with a high-performance intercooler when you could install a bigger throttle body and improve your car’s performance?

As you might know, the stock one is not the best for making more power.

On the other hand, a larger throttle body will allow more air into your engine, which increases your overall HP.

Frequently Asked Questions (FAQs)

You know pretty well the stock parts of your vehicle don’t cut it anymore, but learning about performance upgrades is somewhat tricky. So, here’s some exciting information to give you a head start:

How can I make my 4.6 F150 faster?

One of the easiest ways to make more horsepower is to install a Diablo tuner and a cold air intake. Those two upgrades will increase your vehicle’s horsepower.

Do spark plugs increase performance?

Sparks plugs alone won’t improve your performance unless the previous ones are bad.

Yes, cold air intakes increase horsepower. Keep in mind that these intakes are designed to flow more air into the engine, thus eliminating all the stock intake restrictions. And they’ll make your car sound louder.

Can exhaust headers increase horsepower?

Yes! Exhaust headers are designed to increase horsepower. In fact, if you’ve already done your exhaust and intake, installing a set of headers will drastically improve your vehicle’s performance.
