6.7 Powerstroke Modifications That Won't Void Its Warranty

The 6.7-Liter Powerstroke is a popular engine for many reasons. It's reliable, has plenty of power, and can tow a heavy load. But, like any engine, you can improve it with aftermarket parts.

Several modification options are available if you're looking to add more power, torque, or fuel mileage to your 6.7-Liter Powerstroke without voiding the warranty.

Here are a few mods that won't void your 6.7-Liter Powerstroke warranty:

Cat-back Exhaust

Adding a cat-back exhaust is one of the best ways to increase power and fuel mileage in your 6.7L Powerstroke. Moreover, it's a simple mod that you can install without voiding your warranty.

A cat-back exhaust will improve exhaust flow and allow your engine to breathe better. This, in turn, will increase power and fuel mileage.

Suspension System

Adding a suspension system is another great way to improve the handling and performance of your 6.7L Powerstroke.

A suspension system will improve the ride quality of your truck and allow you to tow and haul heavy loads with ease. In addition, it's a great mod for those who use their vehicle for work or play.

Performance Module

Adding a performance module is a great way to increase power and torque without voiding your warranty. However, there is some confusion between a performance module and a tuner.

A tuner is directly plugged into the truck's computer and alters the truck's programming. While it can increase power and fuel economy, it can lead to issues with your car and void your warranty. On the other hand, a performance module is a stand-alone unit that doesn't alter the truck's programming.

The performance module is installed under the truck's hood and intersects the fuel pressure sensor and manifold sensor. The module manipulates the signals going to and from the ECM, allowing for more fuel and boost to the engine.

Since it doesn't override the ECM as a tuner does, it is undetectable and doesn't void the Ford warranty.

Cold Air Intake

Installing a cold air intake is one of the best ways to increase power and fuel mileage. It's a simple mod that can be done in an afternoon and doesn't require special tools or skills.

Like a cat-back exhaust, a cold air intake will improve airflow to the engine and help the truck breathe better.

Exterior Modifications

Adding exterior mods is a great way to customize the look of your truck and make it stand out from the crowd. But did you know that some exterior mods can also improve performance?

For example, adding a bed cover or tonneau cover will improve aerodynamics and help your truck slip through the wind. This can lead to better fuel mileage and performance.

In addition, you can change the hood for a carbon fiber or fiberglass version. These materials are lighter than the stock hood and can lead to better performance.

So, there you have it. These are a few modifications that won't void your 6.7-Liter Powerstroke warranty. Be sure to consult with a professional before making any changes to your truck to ensure they won't void the warranty.

What Is Ford's Warranty?

When purchasing a 6.7-Liter Powerstroke or any Ford vehicle, you will want to be aware of Ford's warranty.

Ford offers a 3-year/36,000-mile bumper-to-bumper warranty and a 5-year/60,000-mile powertrain warranty. These warranties cover the cost of repairs for defects in materials or workmanship.

The bumper-to-bumper warranty covers the engine, transmission, suspension, and electrical components. The powertrain warranty covers the engine, axles, wheels, and transmission.

Other Ford Warranties

In addition to these warranties, Ford also offers a corrosion perforation warranty that covers rust-through holes in the body for five years with no mileage limit.

Ford also offers a diesel engine warranty covering the engine for five years/100,000 miles for diesel owners. The diesel warranty covers the water pumps, gaskets, seals, and various sensors.

Lastly, Ford has an emissions warranty that covers the cost of repairs for emissions-related problems for two years/24,000 miles.

However, bigger components such as the catalytic converters, electronic emission control unit, and onboard emission diagnostic device are only covered for eight years/80,000 miles.

This is a lot of information to take in, but it's essential to know what isn't covered under your warranty. That way, you can make the best decision for your truck.

How Do You Increase Fuel Mileage Without Modifications?

There are a few ways to increase fuel mileage without modifying your truck.

First, you can make sure your tires are properly inflated. This will reduce rolling resistance and improve fuel economy.

Second, you can avoid excessive idling. Idling wastes fuel and produces emissions, so it's best to turn off the engine if you're going to be stopped for more than a minute or two.

Third, you can avoid excessive acceleration and braking. These activities waste fuel, so it's best to drive as smoothly as possible.

Fourth, you can use cruise control when appropriate. This helps maintain a consistent speed and can improve fuel economy.

Finally, you can keep your truck well-maintained. This includes regularly changing your oil and using the proper fuel for your engine.

You can improve your truck's fuel economy without modifications by following these tips.

What Happens If My Warranty Is Voided?

When a warranty is voided, the manufacturer is no longer responsible for covering the cost of repairs. This means that you will be responsible for paying for all repairs out of pocket.

You can void warranties for several reasons, such as modifying the vehicle, using non-approved parts, or failing to maintain the car properly. For example, if you don't change your oil regularly, you could void your engine warranty.

If you are planning on making any changes to your truck, consult with a professional first to ensure they won't void the warranty.

Does Adding A Subwoofer Void Ford's Warranty?

Technically, installing a subwoofer in your truck shouldn't void the warranty. However, if the subwoofer is installed improperly and damages another part of the vehicle, you could void the warranty.

New vehicles come equipped with impressive sound systems, so there's no need to add a subwoofer. However, if you decide to add one, be sure to have it installed by a professional to avoid issues.

In general, it's best to avoid making any modifications to your truck that could void the warranty. These modifications can be expensive and are often not necessary.

Will A Lift Kit Void Ford's Warranty?

Adding a lift kit is a cool way to customize your truck, but it can void the warranty. This is because lift kits can alter the suspension and cause other truck parts to wear down prematurely.

If you decide to add a lift kit, consult with a Ford mechanical professional first. They can help you choose a kit that won't void the warranty, and they can also install it properly to avoid any issues.

In other words, if Ford installs it, it's less likely to void the warranty. Don't take your modifications to a 3rd party as they more likely will not be covered.

Third-party modifications are a huge risk and not worth the headaches if something happens and needs repairs.
