Engineered to replace the factory hoses which are prone to failure under the high stress of competitive and high-performance applications, these PPE hoses are designed to withstand the pressures of racing and competition far beyond the capabilities of OE components.

• Superior Strength: Reinforced with 5 plies of polyester fibers for unmatched toughness.
• High-Performance Materials: Fluorocarbon lining for enhanced lubricity and chemical resistance, with silicone rubber construction capable of enduring constant boost pressures from -76°F up to +437°F.
• Compatibility: Directly replaces GM Part# 15034797, ensuring a perfect fit.

PPE Performance Silicone Hoses distinguish themselves by their resilience to fuel, oil, chemicals, UV, and ozone, maintaining integrity even under the extreme conditions of heavy use. Available in various sizes and configurations, there's a PPE hose suited for every design application, making them indispensable for those seeking reliability and superior engine performance.

Note: Given the hoses' 6mm wall thickness, ensure that hose clamps are 1/2" larger in diameter than the hose ID for proper installation.
