FA-6296 High-Flow Washable Air Filter
After 40 years on diesel engines, I’ve learned that airflow problems rarely announce themselves — they show up as heat, soot, fuel burn, and regen headaches. OEM 6296 paper filters work when they’re new, but once they load up, restriction climbs fast. That restriction hurts boost response, raises EGTs, and feeds the DPF more soot than it ever needed.
That’s why I designed the FA-6296.
This is a high-flow, washable air filter, engineered to maintain airflow over time instead of suffocating the intake as miles add up. The synthetic filter media resists collapse and airflow drop-off under sustained load, keeping the turbo operating in its efficiency range and combustion stable.
Sealing matters just as much as airflow. The FA-6296 uses OEM-matched sealing geometry so air goes through the filter — not around it. No bypass means better protection for the turbo, charge-air cooler, and engine internals.
Instead of throwing away paper filters every service interval, you wash the FA-6296, oil it correctly, reinstall it, and keep running. One filter replaces years of disposable elements, reduces downtime, and lowers long-term operating cost without sacrificing engine protection.
Compatibility Note:
If your truck or equipment calls for an OEM 6296-style air filter, the FA-6296 is a direct drop-in replacement with no modifications required.

Competitor Differentiation
Disposable paper filters are designed to be thrown away — not to maintain airflow. As they load with dirt, restriction climbs and performance falls off.
I built the FA-6296 to hold airflow steady over time, not just test well when it’s clean. Washable media keeps restriction lower, sealing surfaces actually seal, and the filter doesn’t become trash after one dirty service cycle.
Disposable filters keep you buying. A properly engineered washable filter keeps your engine breathing right and your operating costs under control.
