When it comes to the performance of your engine, Dura-Lite understands that every part of the process matters to make sure you maximize your uptime. The Dura-Lite Evolution charge air cooler features a patented high temperature silicone grommet tube-to-header seal system that allows tubes to expand and contract in the grommet/header, eliminating typical failure and leakage. The tanks are reinforced to reduce premature failure, and an offset outer fin design provides consistent performance by minimizing debris build-up. Dura-Lite Evolution charge air coolers are dyno tested to ensure highest performance and are engineered for performance, economy, longevity, and EPA certification. This Dura-Lite charge air cooler is tested under water to guarantee leak-free status before leaving the factory and fits Freightliner applications. Dura-Lite offers a 7 year warranty on this product unless otherwise specified, one of the best on the market.
