• Exhaust Systems for 2011 - 2016 LML Duramax: Replacing your stock exhaust with a high-flow system improves airflow, reduces backpressure, and lowers EGTs (Exhaust Gas Temperatures), resulting in more efficient engine operation and an increase in horsepower.
• Cold Air Intakes for LML Duramax: Installing a cold air intake allows your engine to pull in cooler, denser air, which helps with combustion and leads to gains in both power and fuel efficiency. This upgrade can have a noticeable impact on the performance of your 2011 - 2016 LML Duramax.
• Injectors for Duramax LML: Over time, stock injectors can lose their edge. Upgrading to high-performance injectors helps ensure optimal fuel delivery, restoring lost horsepower and improving overall fuel economy in your LML Duramax.
