FA-2722 High-Flow Washable Air Filter – Replaces OEM 2722-Style Paper Filters

FA-2722 High-Flow Washable Air Filter – Replaces OEM 2722-Style Paper Filters

FA 2722 High Flow Filter

When I climbed into the seat of that W900L and saw the stock paper filter choking under boost, I knew we needed a serious upgrade. That’s where the FA 2722 comes in. I designed it for heavy-duty long-haul use on trucks fitted with the Detroit Diesel 12.7 DDEC4 engine—machines that haul loads up mountain grades, sit idle in traffic, or slog through dusty job sites.
Why airflow matters: when your engine is forced to breathe through a clogged filter, turbo pressure drops, EGTs climb, throttle response suffers, and fuel economy drops. The FA 2722‘s high-flow washable design keeps restriction low, meaning the turbo spools faster, the CAC sees less heat soak, and the whole engine package stays sharper.
OEM paper filters are fine for mild duty—but out here in real trucking, they turn into restriction bricks by 10-20K miles. They lead to more regens, more downtime, more guesswork. I engineered this unit to pull out, clean, reinstall and keep going. That means fewer filter changes, fewer surprises, and long-term cost savings.
Fitment is tight for the Kenworth W900L + Detroit Diesel 12.7 DDEC4 combo—so you know the sealing surface, the canister mount, the bypass protection all work together. I’ve seen the difference on shop floors: cleaner air, smoother boost curves, fewer “why did the turbo die” phone calls.
If you haul hard, climb grades, spend days on the road, or run fleets with uptime as the top KPI—this filter is your insurance. When I built the FA 2722, I had one goal: keep your air clean, your engine breathing, and your costs down.

(OEM #s tbd) Kenworth W900L / Detroit Diesel 12.7 DDEC4 Based on OEM match FA 2722

Features & Benefits

Features:

  • Premium washable media — engineered for multiple cleanings instead of single-use paper

  • Rigid aluminum canister with high-integrity sealing flange and clamp system

  • Large surface area + optimized pleat geometry to maximize airflow while still trapping dirt

  • Compatible wrap option available for custom fleet graphics

  • Designed specifically for Detroit Diesel 12.7 DDEC4 in Kenworth W900L, so fitment and sealing are exact

Benefits:

  • Improved throttle response and turbo spool-up thanks to lower restriction

  • Fewer regens and lower EGTs because cleaner air equals better combustion and less soot buildup

  • Long-term savings — no frequent disposable filter replacements, fewer service interventions

  • Less downtime — cleanable design means you’re back on the road faster

  • Better engine life — keeping the turbo and CAC cooler and cleaner reduces wear

Competitor Differentiation

Here’s the no-fluff mechanic truth: many filters claim “high flow” but still choke when the engine is under load. Others are washable in theory but built with cheap media or weak sealing, so they bypass dirty air or collapse under boost. I designed the FA 2722 from the ground up to fix those exact gaps: strong sealing surface so no dirty air sneaks in, high-density pleats so the flow stays strong even when you rack up miles, and construction built for heavy trucks, not light-duty fluff. If you’re serious about uptime and engine protection, this one beats the common solutions out there by a mile.
