The Full Tilt manifold for the 12.7L Detroit Diesel engine is designed to significantly improve performance and fuel economy in Freightliner and Western Star trucks with pre-emission, non-EGR engines. This high-performance manifold replaces OEM part #23532122 and offers substantial upgrades over the factory design.
Enhanced Airflow and Reduced Temperatures
The Full Tilt manifold features a unique joint configuration—male on the end piece and female on the center section—which is the reverse of the OEM design. This innovative approach optimizes airflow to the turbocharger, resulting in a noticeable increase in fuel mileage, typically between 0.2 and 0.3 mpg. Furthermore, the manifold is coated with CeramiChrome, a high-temperature ceramic coating that reduces heat and further improves air velocity. This coating contributes to lower manifold temperatures (by approximately 300°F) and lower exhaust gas temperatures (EGTs) by 80-100°F.
Durable Construction and Leak-Free Design
Crafted from a proprietary high-quality blended steel, the Full Tilt manifold boasts exceptional strength and heat resistance. Thicker exhaust flanges and center dividers ensure durability even under the most demanding conditions. Precision-engineered joints with tighter tolerances and 50% more surface contact are press-fit to guarantee a leak-free seal.
Engineering Excellence for Optimal Performance
Extensive engineering efforts have gone into eliminating sharp bends and restrictions in the manifold’s internal passages, creating a smooth and efficient path for exhaust gases. Hand-smoothing further refines the interior, maximizing airflow to the turbocharger. Each Full Tilt manifold undergoes rigorous flow testing to ensure it delivers at least 20 CFM more per port than the OEM equivalent. This meticulous attention to detail translates into reduced turbo lag and improved overall engine responsiveness.
Made in the USA Quality
The Full Tilt manifold is proudly manufactured in the USA, ensuring the highest standards of quality and craftsmanship. This commitment to excellence provides a reliable and long-lasting solution for boosting the performance of your Detroit Diesel 12.7L engine. By reducing heat, improving airflow, and enhancing durability, the Full Tilt manifold offers a substantial upgrade over the factory design, leading to increased fuel efficiency, reduced operating costs, and improved overall performance.
