Z-RAM Firing Bolt + Powerkit.50 V2 for Umarex HDP50 TP50,  export valve,  Gen2 + Gen1 , 7.5j version 20-30J

 

Includes Powerkit.50 V2 + Z-RAM Stainless Steel Bolt
Output: up to 30 Joules

Take your Umarex HDP50 / TP50 to the next level with this high-performance combo! The Powerkit.50 V2 delivers massive output (20–30J), and the included Z-RAM Stainless Steel Bolt lets you skip the nightmare of removing the factory aluminum pin — which often breaks or gets damaged. Just screw the new pin into the steel bolt, drop everything in, and go. Easy install. Big results.

💡 Why this combo saves you stress:
Removing the original Power-Pin from the factory bolt is a major pain — it’s press-fitted, fragile, and frustrating. This kit solves that by giving you a ready-to-install steel bolt. Time saved. Nerves spared.

This stuff really works fast and improves mpg like you won’t believe
Size: 300 Milliliter
I’ve tried many other types of fuel injector cleaners but this brand is amazing. I ran my truck down to less than a quarter of a tank of gas and poured it into the tank. I then drove 30 miles to an appointment and spent an hour in the appointment on the way home I noticed my mpg had gone up significantly. My truck tells me how many miles per gallon. I’m getting as I drive. I had gotten a code and I replaced the mass air filter and found a slight crack in an air hose, which I replaced that help with my code a little bit, but cleaning the fuel injectors with this product made such a significant difference. I just simply had a hard time believing it, but it’s true. I’m done with all those other brands of fuel injector cleaners which never really seemed to help much if you really want an amazing experience give this product to try.

Perfect for the 2016-2017 Honda Accord. Specifically the two holes on the sides of the front grille that are on top of the headlights.
