  • Product Description


    The Power Plus 357 Nozzle is the best upgrade for most TDIs equipped with the automatic transmission, and A3/B4 chassis TDIs. It is also an effective upgrade on other VE TDI cars fo r improving fuel economy. 192.9um 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 357 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') Such a set up will support 110-125 whp.

    If you want to to buy a single nozzle CLICK HERE



    Important Note:  We highly recommend our Hot-Swap injector program featuring Injector Calibration Service.  It is the only way to properly set up your new Genuine Bosio nozzles for ideal performance.  Please  CLICK HERE for more details.


    Purchase any set of Genuine Bosio ALH nozzles from kermaTDi and pay for Mounting, calibration and flow balancing and we will ship a set of ALH injectors mounted with your nozzles and eliminate downtime of your vehicle.

    A $600.00 core deposit will be charged at the time of purchase. Once we receive your used set of ALH injectors complete* and in serviceable condition** to us you will receive your full core charge back without any hidden fees or charges!

    *Complete injectors mean (3) injectors from cylinders 1, 2 and 4 as well as the #3 injector. The #3 injector is expected to arrive without the T return nipple and banjo bolt. Injectors must be returned un-opened and with the nozzles installed to prevent loss of internal components. Note: If you require the nozzles mounted in your core injectors be returned to you, a modest fee of $10.00 will be charged and the nozzles upon receipt by us will be removed, bagged and shipped back to you via USPS.


    **Serviceable condition means no marring of the injector bodies such as vice grip marks or other surface damage to the return nipples and threads. The #3 injector must be in good condition without ANY damage, fraying or tearing of the sensor wire. If there is any damage to the injectors that renders them damaged or unserviceable we reserve the right to retain your full core deposit.


    Note: To prevent damage to the injectors you must remove the injectors using a slide hammer thus extracting them upward and out of the head. This will prevent damage to the injectors and allows easy and quick extraction with minimal effort. This extractor is available for purchase at low cost through kermatdi and there are plans to make your own on the net. In either case using this extraction method is the surest way to remove the injectors without damage.


    === We realize that at times injectors may be damaged we would like to remind you that we offer a complete set of NEW injectors at very competitive prices shipped to you ready for install.

    ***How To Instructions for injector nozzle installation will be in a link in your invoice. You must copy and paste to a web browser and have adobe acrobat reader installed.***

    1. Definitely an upgrade from stock

      At 186k the Jetta was a little sluggish, these nozzles did the trick. Makes me wish I had done the swap a long time ago. on 9th Jul 2017

    2. Works great!

      This is a good way to add a little more power without having to do any modification really other than check/adjust the injection quantity once installed. These did not create any smoke but did give me a noticeable increase in power. I'm very happy with the way they turned out. on 1st Apr 2017
