Peterbilt 367 Engine & Performance Parts

Frequently Asked Questions About Peterbilt 367 Engine & Performance Parts

Will these engine and performance parts fit my Peterbilt 367?

Most parts in this category are designed to fit the Peterbilt 367, but fitment can vary depending on the engine make and model installed in your truck (such as PACCAR, Cummins, or Caterpillar), as well as the model year of your truck. Always check the product listing for specific engine and year compatibility, and reach out to our team if you are unsure before placing your order.

What materials and finishes are available for these parts?

Depending on the specific part, you will find options in materials such as aluminum, steel, and stainless steel, along with finishes like chrome, polished, or powder-coated. Material and finish affect both durability and appearance, so consider your truck's environment and maintenance preferences when choosing.

Can I install these parts myself, or do I need a professional?

Many components, such as air intakes, filters, and exterior engine trim pieces, can be installed with basic tools and mechanical knowledge. However, parts that involve engine tuning, exhaust systems, or emissions components may require professional installation to ensure proper function and compliance. If a listing includes detailed instructions or hardware, that is a good indicator of a straightforward install.

Will installing performance parts affect my engine's warranty or emissions compliance?

Some performance parts, particularly those related to exhaust, emissions, or engine tuning, may impact your factory warranty or your truck's compliance with EPA and DOT regulations. We recommend reviewing your engine manufacturer's warranty terms and confirming that any part you choose meets applicable emissions standards for your operating region before installation.

How do I know if a part will actually improve performance or durability?

Product descriptions on our site outline the intended function of each part, whether that is improved airflow, reduced heat buildup, easier maintenance access, or increased durability under heavy use. If you're unsure whether a specific part addresses your truck's needs, our customer service team can help you choose based on your engine type and how you use your truck.
