Silicon Bypass valve bipipe inlets
This hose pair is designed to replace the outrageously expenive, failure-prone factory rubber hoses with a boost-friendly automotive silicone one. Factory hoses sell for over $80 each, while you get both here for under $35.
This durable, reinforced high quality silicone hose was modeled directly off of the factory part to ensure perfect fit and finish.
