You know that whining sound your engine makes when it’s struggling to breathe? That’s often your inner air filter crying for help. While your outer filter catches most of the dirt and debris, this inner element is your engine’s last line of defense against the fine dust that’ll turn pistons and cylinders into expensive scrap metal. When you’re working dusty harvest fields or cultivating dry ground, this little filter keeps the microscopic particles from sneaking past and doing real damage.
What Makes This Filter Special
- Fine filtration media traps the particles that cause the most engine wear—stuff so small you can’t even see it
- Precise fit seals tight against your air box housing so nothing sneaks around the edges
- Heavy-duty construction won’t tear or collapse under the high airflow these turbocharged engines demand
- Works as part of a two-stage system with outer filter 1673 for complete protection
- Direct replacement that meets original Deutz specifications
Where This Filter Shines
Your Deutz Agrostar combining soybeans in September dust or that DX120 working cultivation when there hasn’t been rain in weeks—these are the conditions where this inner filter really earns its keep. It’s designed for the demanding work these tractors do, from heavy tillage that kicks up clouds of dirt to harvest operations where chaff and fine particles fill the air.
Built to Last
This isn’t a generic filter trying to do a Deutz job. The filtration media is specifically designed to handle the high airflow these engines pull while still catching particles down to microscopic levels. It maintains its filtering efficiency even when conditions get tough, keeping your engine internals clean when it matters most.
Installation Tips
Simple swap—remove the air cleaner cover, pull out the old inner filter, and slide in the new one with the airflow arrow pointing toward the engine. Always change this inner filter when you replace your outer filter, and don’t try to clean and reuse it. The fine media can’t be properly cleaned without damage, and the few dollars you might save isn’t worth risking engine damage.
