Pacific Performance Engineering 115901200 6mm 5-Ply Silicone Boost Hose Kodiak GM 6.6L Duramax

The Pacific Performance Engineering (PPE) 115901200 is a premium 6mm wall, 5-ply silicone performance hose engineered as a direct replacement for GM OEM part number 15020973 on the Kodiak GM 6.6L Duramax platform. Built to far exceed the capabilities of stock rubber hoses, this PPE silicone hose is the ideal upgrade for high-demand applications ranging from daily driving and towing to racing and sled pulling.

Key Features:

• 5-Ply Polyester/Nomex Reinforced Construction — multiple reinforcement layers deliver exceptional strength and burst resistance
• Working Pressure: 70 PSI (4.8 BAR) — rated for sustained high-boost applications
• Burst Pressure: 207 PSI (14.3 BAR) — superior margin of safety over OEM hoses
• Fluorocarbon Inner Lining — provides better lubricity and strong resistance to fuel, oil, and chemicals
• Wide Temperature Range: -76°F to +437°F — maintains structural integrity across extreme operating conditions
• UV and Ozone Resistant — resists environmental degradation for long service life
• 6mm Wall Thickness — built to handle constant boost pressure without collapsing or blowing out

PPE silicone hoses are designed to handle the rigors of increased pressures during racing and competition, while also serving as an excellent upgrade for everyday towing and driving demands. Unlike stock hoses, PPE's silicone construction will not blow out under pressure.

OEM Cross-Reference: GM 15020973

Important Installation Note: Due to the 6mm wall thickness, hose clamps must be 1/2 inch larger in diameter than the hose ID for proper fitment.
