The Power Plus 520 Nozzle is the best upgrade for most MK4 TDIs equipped with the manual transmission. It is also an effective upgrade on other VE TDI cars. 214.6um orifice diameter.

The OEM and their suppliers must compromise quality and performance characteristics to meet production numbers. These limitations are compounded by the bean-counters in the corporate office always demanding lower cost.

The Fratelli Bosio Power Plus philosophy removes these artificial OEM limitations, by applying industry-leading technology to decades of injector nozzle manufacturing know-how.

Each Power Plus nozzle embodies thousands of hours of testing to achieve the most effective design, without compromise.

The result:

- optimized spray pattern

- closer tolerances

- hardened wear surfaces

- More power than the OEM parts

- More torque than OEM parts

- Less exhaust smoke for the same power output

- Improved economy in many cases

The Power Plus 520 is recommended for most equipment configurations.

The absolute best results will be obtained when used in conjunction with the Q Loader Flash Programmer and Kerma Tuning (see 'ECU Tuning') and a mild turbo upgrade. (see drop in turbo upgrades) Such a set up will support up to 150-160 whp.
