Balanced Performance – Airflow, Temperature Control, and Fuel Efficiency
Every 6.7L Diesel intake horn from SPELAB is more than just a structural replacement—it’s a complete upgrade to your diesel engine’s breathing system. Using advanced airflow engineering and high-temperature resistant materials, these Dodge Ram 6.7L diesel intake manifold products deliver a balanced improvement in power, heat management, and efficiency.
1. Enhanced Airflow: Help Your Engine Breathe Better
With larger internal passages and optimized flow geometry, SPELAB intake manifolds deliver up to 88% more airflow compared to stock (especially true with the Intake Horn model). This allows significantly more oxygen into the combustion chamber, improving throttle response, engine output, and overall driving smoothness.
2. Superior Heat Management: Reduce EGT and Protect Your Engine
When towing or under heavy load, diesel engines can suffer from dangerously high Exhaust Gas Temperatures (EGTs). SPELAB’s air intake manifold designs reduce EGT by 50–200°F, relieving stress on your turbo, pistons, and other high-heat components—perfect for long hauls and demanding work environments.
3. Better Fuel Economy: Efficient Combustion, Real Savings
By optimizing airflow distribution, SPELAB intake manifolds promote more complete combustion. The result? Real-world fuel economy gains of 0.5 to 1 MPG for Dodge Ram 2500 and 3500 trucks in both highway and load-intensive conditions—saving drivers money over time.
4. Built to Last: Premium Materials and Structural Integrity
Each intake manifold is crafted from mirror-polished stainless steel or cast aluminum, offering outstanding heat resistance and corrosion protection. With reinforced wall thickness and precision welding, these manifolds are built to withstand the high-pressure, high-heat environments of heavy-duty diesel use—ensuring long-term reliability.
