NJPerformance dual valve springs set for 1.9 TDI 8v VE VEP Engines
Performance dual valve springs set 1.9 TDI 8v VEP. The set prevents valve float under high boost pressures due to springs greater stiffness compared to the OEM springs. The small spring has a reverse winding, which allows safe lifting of the working. If the valve springs are weak, the springs may not be able to push the valves all the way shut before the next opening cycle begins. If the valves fail to close, the cylinders will lose compression causing the engine to. Misfire and lose power. In some worse situation Pistons can also hit the valves. Direct fittment and require no machining. Installed seat pressure – 30kg (+35% over stock single spring and +50% over stock dual springs). 9mm lift pressure – 73 kg (+20% over stock single spring and + 35% over stock dual springs). Lift – 13.7 mm. Models that the springs fit. 1Z / AHU / AFN / AGR / ALH / AHF / ASV / ALE / AVG.
