Feature 1In the field of highperformance driving, springs are still the best way to regulate boost. Whether your goal is a moderate 3PSl, 14PSl or a custom boost level, the spring can achieve. 2Each wastegate actuator spring is designed to work individually or in groups, so you can mix and match different springs to get the best PSI. 3By stacking up to three springs in your waste gate, you can achieve the desired boost speed and the horsepower you need. 4It is exquisitely processed from highquality lowcarbon steel, has abrasion resistance, is not easy to damage, and has a long service life. 5Has extremely high heat resistance, can cope with difficult environments, it is a good replacement on the market.Item Type:Waste Gate SpringMaterial: Carbon SteelPurpose: Turbine Waste Gas Valve14PSI Spring:Initial Outer Diameter: Approx. 48.7mm/1.9inInitial Length: Approx. 105mm/4.1in8PSI Spring:Initial Outer Diameter: Approx. 37.8mm/1.5inInitial Length: Approx. 62.3mm/2.5in .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List2 x Waste Gate Spring
