Hey Dudes, Jake here:
When you use a DPF delete kit on your diesel truck,
you're removing the Diesel Particulate Filter (DPF).
This filter works with Diesel Exhaust Fluid (DEF) to reduce emissions.
Once the DPF is gone, your truck won't need to use DEF anymore because there's no filter to work with it.
In short: No, after installing a DPF delete kit, you won't need DEF fluid for your truck.
This can save you both time and money since you won't have to buy or fill up on DEF anymore.
However, always remember that using a delete kit might have legal implications depending on where you live,
as it changes the emissions system of your truck.
Make sure you're aware of local regulations before making any modifications.
Hope that clears things up! If you have more questions, feel free to ask.
