2010-2012 Cummins Turbocharger Boost Tubes (25998)

Fits

Banks hot and cold side tubes have up to 65% greater flow area than stock tubes. Produced from high-quality aluminized steel, the tubes are mandrel bent and have a constant diameter. This allows for a quicker turbo spool. Better flowing intercooler tubes improve retention of boost pressure (increases density) between turbo, intercooler, and intake resulting in maximum horsepower.

The red powder-coat finish stops before the end of the tubes for better grip ensuring our 4 and 5-ply heavy-duty high-temperature silicone couplers hold tight under high-boost conditions. Spring-loaded constant tension clamps maintain a stronger grip to prevent leaks or blown boots.
