What is DEF?
DEF, or diesel exhaust fluid is a liquid that is injected into the exhaust system. This part of the exhaust system is called the SCR, or the selective catalytic reduction. It is designed to remove nitrogen oxide emissions from the diesel engine. The issue with diesel exhaust fluid is that because it is 67% water, it can freeze during the winter. This can crack the DEF tank and lead to other problems. Some manufacturers use diesel exhaust fluid as their main, or only, source of emissions control. This can result in high costs, ensuring that the DEF is always full. The catalyst that is used for the DEF is not as restrictive compared to the diesel particulate filter. This means that it can stay in place, even after a reflash has taken place. We recommend that you rinse out the DEF system with water after the fluid has been drained. Diesel exhaust fluid if left alone for a long period of time can crystalize. That is why it is best to make sure everything is clean!

Emissions tuning is for off-road use only. Please consult your Provincial or State legislation, as this product may not be street legal. Removal of emissions systems cannot be performed on vehicles that are registered for highway use. It is up to the Consumer to know and understand their local legislation prior to purchasing.
