3 different options available in progressively stronger stages!
– Piston has over than 50% area than OEM (OEM Piston Size: 8.0mm versus VIS Piston Size: 9.xxmm)
– Piston head optimized for ideal hydrodynamic flow
– Piston surface hardened and heat treated in 3 diferent stages
– Uses OEM-style spring keeper,redesigned piston tip end for more stability inside retainer,ensures that it will not weaken by constant contact with the cam follower,tested at 12.000 rpm
-Oem spring is used for protecting cam follower
-Get the most out of the direct injection fueling system on your 2.0T FSI. Not only does the upgrade increase the amount of fuel your high pressure fuel pump can deliver but it will also decrease the duty cycle of the N276 solenoid on your pump. Lowering the duty cycle of the N276 will extend the life of this solenoid – an item that commonly fails on these pumps but isn’t available separately.
-Even a standard stock or Stage 1 car will see benefits from running these internals,not only do you extend the life of the N276 solenoid since it’s not working as hard but you already have an upgraded HPFP giving you more headroom in your fueling system should you decide to do more modifications.
-Simple install on stock car will give 10 bar rail pressure
-can sustain easy 600 hp and over 150 bar tested now for over 4 years in many configurations,and different hardware/software setups
