Injen 19-20 Chevrolet Silverado 1500 V8-5.3L Evolution Intake - EVO7104

When it comes to durability, Injen's Evolution series can't be beaten! Some of our competitors use an inferior HDPE linear polyethylene to mold their intakes. HDPE is cheap for manufacturing but doesn't come close to the strength and durability of XLPE polyethylene. The XLPE that Injen uses has 20 times the environmental stress crack resistance of HDPE, 10 times the molecular weight of HDPE, and 5 times the impact and tensile strength of HDPE. In other words, Injen's Evolution intake systems are built tough and designed to last!
