Quality and reliability: OEM parts are manufactured to meet the exact specifications of the engine manufacturer. The manufacturer ensures that the parts are made to the highest quality standards, using the best materials and production processes. This means that OEM parts are more reliable and durable than aftermarket parts, which may be made to lower quality standards. Compatibility: Using OEM parts ensures that the engine will operate as intended without any compatibility issues. OEM parts are designed to fit perfectly into the engine and work seamlessly with other components. Using non-OEM parts may result in compatibility issues that could affect the engine's performance, efficiency, and even safety. Warranty: OEM parts come with a warranty from the manufacturer, which provides additional peace of mind for the customer. The warranty covers the cost of parts replacement or repair in case of defects or malfunctions. Using non-OEM parts may void the warranty, leaving the customer responsible for any repairs or replacements. We have the best warranty in the business Safety: OEM parts are tested and approved by the engine manufacturer to ensure they meet all safety standards. Using non-OEM parts may compromise the safety of the engine and potentially lead to accidents or injuries. For example, using non-OEM parts in the engine's fuel system may result in leaks or other malfunctions that could cause fires or explosions. Using OEM parts in a remanufactured engine ensures the highest quality and reliability, compatibility, warranty coverage, and safety. These factors are critical to ensuring that the engine operates at peak performance and efficiency, and that it lasts as long as possible. While OEM parts may be more expensive than non-OEM parts, the benefits they provide in terms of quality, reliability, and safety make them well worth the investment.
