SPELAB has released a performance intercooler for the 2011-2016 LML 6.6L Duramax. A high-powered 6.6L engine needs an intercooler that can effectively reduce intake temperatures and withstand high pressures. The SPELAB 6.6L Duramax intercooler is manufactured with heavy-duty cast aluminum end tanks and a stout bar-and-plate core, designed to decrease intake temperatures, improve airflow, and reduce pressure drop. By decreasing pressure drop this intercooler will extend the life of your turbocharger and improve the efficiency of your 6.6L Duramax. The SPELAB 6.6L Duramax intercooler features a core with greater volume than the factory cooler; this results in numerous performance benefits including increased pressure tolerance and lower EGTs. We engineered this intercooler to provide substantial benefits on a stock truck, and also to support the power and boost levels of a highly modified truck. Offered in black, the SPELAB 6.6L Duramax intercooler, like all of our Duramax performance parts, comes protected by our signature Lifetime Warranty.
