High pressure fuel pump upgrade piston for 4.0 TFSI
What does the High Pressure Fuel Pump upgrade kit exist for?
During the tuning process and increase in power, stock high-pressure fuel pumps usually quickly reach maximum level of output and capacity.
On some cars, this problem can appear even on Stage 2 level of upgrades, leading to "fuel cuts" especially in the midrange (3000-5000 rpm), that can lead to disastrous consequences...
The modified plunger pair (as in the picture) in the injection pump increases its productivity by 32+%, which is quite enough even with Stage 3 level of modifications, when more effecient turbochargers are installed.
Not only increases the throughput, but also increases the pressure and shape of the injection, thereby allowing to increase the efficiency of the engine output while tuning.
