Hoses are currently shipping as EPDM (OEM) material.
Updates:
NEW Apr 2025: Nicer fittings, fancy hoses. Same price. Fancy, OAT Lined silicone hose assembly adopted over from EVO kit.
All billet and laser cut parts made and finished in the Pacific Northwest. Hoses made in the UK by certified british people.
Hose assembly includes 90deg union to mate with stock EGR to thermostat hose for perfect clearance with manifold, and align the temp sensor parallel to the cylinder head so there is zero strain on the harness. If you buy a competitors kit, PLEASE follow this routing and buy a 3/4″ 90, otherwise your hose will rub on the intake pipe bracket or the manifold and eventually fail.
