Below you will find basic 4DPF offer of Isuzu NPR Delete.

Isuzu NPR DPF+def Delete Kit
Isuzu NPR Delete Kit for DPF+DEF is designed for Isuzu Trucks equipped with both Diesel Particulate Filter (DPF) and SCR (Selective Catalytic Reduction – also called DEF or AdBlue)
The installation of Isuzu NPR Delete Kit is completely non-invasive and does not void warranty in any way as it does not make any changes to the original software. It is installed in place of the original sensors like a digital bypass.
With Isuzu NPR DEF Delete Kit installed you can forget about adding exhaust fluid or expensive and time consuming DPF cleaning. The kit will still indicate fluid level on the dashboard and filter regenaration in your Isuzu truck will become a thing of the past.
This version of the Isuzu NPR DEF Delete fits not only the Isuzu NPR but also other Isuzu Trucks like: Isuzu NPR HD, Isuzu NQR or Isuzu NRR.
If you’re Isuzu Truck is not equipped with SCR system and does not take DEF have a look at our offer for Isuzu NPR DPF Delete Kit below.

ISUZU NPR DPF DELETE KIT
Isuzu NPR DPF Delete Kit for DPF only Isuzu Trucks – this version of the Isuzu Delete was designed for the older type of Isuzu Trucks but it fits more than just Isuzu NPR.
For example Isuzu NPR HD, Isuzu NRR, Isuzu NQR or Isuzu D-Max are all supported as well.
The installation principle is the same as with Isuzu NPR Delete Kit for DPF+DEF trucks. Plug and Play installation assures that the warranty will not be voided. Same as with the other kit the software is not changed or modified in any way making this Isuzu NPR DPF Delete Kit completely safe and hassle-free.
Isuzu NPR DPF Delete Kit is the right choice for those that wish to get rid of the emission system without the need for reprogramming, removing the ECU (Engine Control Unit) from their Isuzu Truck and just simply electronically remove the emission without the extra hassle.
Plug and play. Simple and Effective. That’s what Isuzu NPR DPF Delete Kit is.
Once the installation is complete all the physical components of the DPF system can be safely removed from the Isuzu Truck.

Frequently asked questions
How does the emulator installation and DPF removal work?
Installation of the Isuzu NPR DPF Delete Kit is non-invasive, this is achieved thanks to the original plugs that the emulator is equipped with. The plugs match the ones from the machine. Isuzu DPF filter removal with the help of our emulator is fully safe to the engine and does not require any interference with the engine controller whatsoever. After installing the device, the diesel particulate filter must be removed.
How does the installation of the emulator and removal of DPF and SCR work?
Similarly to the installation in machines with just the DPF the emulator must be connected using the plugs which the device is equipped with. Then disconnect the DEF pump controller and disconnect the nitrogen oxide sensors. Connect the emulators plug in the place of one of the NOx sensors, A detailed manual with a complete description of service steps is included in each order.
How does DPF regeneration work after filter removal?
The emulator simulates the operation of an efficiently working emission reduction system. The engine controller does not activate DPF regeneration because the signals generated by the emulator reports that the diesel particulate filter is in perfect condition. Isuzu NPR DPF Delete Kit will make you forget about regen.
Should I continue to add DEF (AdBlue) fluid?
No. The DEF/SCR pump no longer pumps the fluid. Refilling it is not necessary.
My machine has been diagnosed with a defective temparature sensor. Can I install this product?
Yes! Any sensor that monitor the operation of the DPF system becomes obsolete after installing the device, so the sensors can remain damaged or be removed completely.
