5Ply Wire Reinforced silicone upgrade tubes are a must have upgrade for tuned and high powered machines. This kit replaces the factory unstable charge tubes with RPM's industry leading, durable silicone that is heat & burst resistant. This heavy duty 5Ply silicone hose construction boasts a wire reinforced construction, essentially lining the 2nd layer with wire before continuing with the 3 remaining layers of construction. This makes the tubes nearly impossible to expand and burst in any conditions or power levels. While creating smooth interior transitions we have created an easy bullet proof installation all while creating a smooth path of air flow. The smooth free flowing design reduces turbulence while increasing airflow efficiency resulting in the performance you demand from your machine.
