Over time, the factory rubber intercooler boots can wear down, crack and leak. If they burst, or even bleed off air, you're losing precious air for power production. Silicone "cold side" intercooler replacement boots for the 10-12 Dodge/Ram 6.7L Cummins from Glacier Diesel Power can provide you a long term reliable solution. The kit consists of one silicone high pressure intercooler to boost tube coupler and one silicone high pressure boost tube to intake manifold coupler. Made of high quality 4 ply silicone rated for 200 psi, these couplers are made in the USA and are manufactured to withstand the higher boost on modified trucks. This kit also includes stainless spring clamps for an easy to install and secure fit.
