- Optimized spray pattern
- Closer tolerances
- Hardened wear surfaces
- DLC Coated needle for superior wear characteristics with ULSD fuel
- More power than the OEM parts
- More torque than OEM parts
- Less exhaust smoke for the same power output
- Improved economy in many cases
Optimized 216 µm Nominal Hole diameter
ULSD nozzles carry a small premium over the non-DLC types but with nearly double the service life (or more) of the nozzle your direct savings are realized not only thru greater durability but improved function of the nozzle meaning better fuel economy and lower emissions all of which translate into greater longevity of your diesel engine.

Nozzles Explained: Please click here to read the fact sheet.
The key advantage to a DLC coating is the superior sliding surface it creates between two moving parts. This allows significant reductions in friction, and far greater durabiltiy due to reduced reliance on the lubricity of the fuel.
Standard Needle and Nozzle
A standard needle is uncoated and relies on the end result of the precision machining. This leaves very slight imperfections in the surfaces that increase the reliance on the fuel to prevent wear. Also this slightly increases the friction and thus lowers the response time of the needle consequently lowering its overall efficiency.
After speaking to Kerma and their support, I decided to start with these injectors for lightly modifying my car recently purchased 2002 Jetta TDI with 190k on it. I wanted something that would give my car a bit of a boost for acceleration and these have definitely done that. I don't plan on heavily modifying my car but I do plan on chipping it for sure and possibly a slightly bigger turbo - but that's all stuff I'll do as I save up. These were super easy to install and with the Hot Swap program my car was only down for a few hours while we installed and calibrated my car. I will note that it did make starting the car in the extreme cold (0 Fahrenheit and below) a bit harsher however I've never had a problem with it starting. I have noticed an improvement in my fuel economy as well - which surprised me since I enjoy driving my car a little more spirited than before. Definitely a good investment and Kerma did a wonderful job of suggesting the right injectors for my need. Scott B on 8th Feb 2017
I had just put a auto swap in my 2003 Jetta Wagon and started to get a misfire due to the injector. I replaced the injectors in about 2 hours and right away felt a power difference as soon as I started driving.
I would recommend this for anyone that wants just a little more power out of the TDI!!!
It should be the first thing you do so that you have plenty of fuel for the other mods you do in the future.
I have a 3" down pipe to a 2.5" back exhaust with a stage 2 daily clutch. I'm making to the wheels 135 HP and 260 TQ. I am still getting 41 to 45 MPG daily driving. (witch includes some 3rd gear to 5th- 40 to triple digit pulls)
One other thing, the intake tube running from behind the headlight to the intake box. I removed mine and made more power, I also got an over boost condition from it for hitting over 25 PSI just WOT in 5th with the injectors and a straight pipe. the car will learn not to over boost but it will take about a month for it to learn. no code now, and stays at 15 to 17 psi all the time.

Just bought this car with 175,000 and original nozzles and compared with my friends TDI Jetta it needed some help. Kerma advised the 1019's and were very helpful in making the decision. i did the hot swap and am very happy with the results. Just have to go easy to keep tires from spinning and that with an auto. Thanks Kerma!!! Thomas on 23rd Jun 2015
Did the hot swap program and had them pop tested. The results are incredible. Now have a tune. My car is a monster now, smokes black real nice too when u get on it. Recommended for sure . But, if you do these nozzles stage 1 with a tune I recommend a better clutch!!! Trenton Wosmek on 10th May 2015
I got these nozzles from Kerma with the flow balancing and the complementary ECU tune. I dropped them in, and the car is WAY quicker. No additional smoke from what I can tell. It's amazing how moddable these cars are! And this is a GREAT upgrade. Unknown on 27th Apr 2015
We installed the 1019 nozzles after A long conversation about our future plans with our car!
We one the first start up we smoked like a freight train due to the last timing belt change and that mechanic messing with the settings, after getting the setting to what kerma recommended she's a great little wagon now and we're not making conductors jealous!!
We have noticed a increase in the seat of the pants dyno and a very slight increase in fuel economy and that's all good! Tony on 19th Apr 2015
I purchased these nozzles with the hot swap option. great mid to high range. some smoke when pedal is pushed, none at normal driving performance. With a tune I was surprised at the power increase. pulls hard now. Unknown on 11th Feb 2015
