Product Details
- Improve your fuel economy and get cleaner emissions from your car when you add the BlueDEF Diesel Exhaust Fluid to your exhaust stream. BlueDEF is a non-flammable fluid that helps remove nitrogen oxide from your emissions. It converts the NOx into harmless nitrogen gas and water vapor.
