Bosch Engine Air Filter 5436WS for Chrysler & Dodge — High‑Pleat, 98% Particle Capture, Polyurethane Seal

The BOSCH 5436WS Workshop Engine Air Filter is a high-pleat replacement filter that captures 98% of small airborne particles to protect engine internals and help restore fuel efficiency.

Replacing a clogged air filter is one of the fastest ways to recover lost engine performance and lower wear. The BOSCH 5436WS is built for workshop-grade durability: dense pleating for large contaminant capacity, high-velocity cellulose media to reduce intake resistance, and a resilient polyurethane foam seal that resists heat and moisture. Together these elements keep incoming air cleaner while maintaining smooth airflow to the engine.

How does this filter improve engine protection?

The 5436WS traps a high percentage of small particles before they reach the intake, reducing abrasive wear on cylinders and valves. Its many pleats increase the available filtering area so more debris is held without restricting airflow quickly. That combination helps prolong engine life compared with a worn or low-quality filter.

• 98% efficiency at capturing fine airborne particles
• High pleat count raises particle-holding capacity
• Cellulose media minimizes air resistance while filtering

Will this filter affect performance or fuel economy?

Designed for minimum flow resistance, the filter’s cured cellulose media maintains even pleat spacing to allow steady airflow under load. Cleaner air and unobstructed intake reduce the work the engine must do to draw air, which can help restore fuel economy lost to clogged or degraded filters.

• Low-resistance media sustains efficient airflow
• Even pleat distribution prevents uneven flow and hotspots
• Helps recover factory fuel efficiency by replacing dirty filters

How does the seal and construction hold up to real-world conditions?

The 5436WS uses a polyurethane foam seal engineered for elasticity and long-term sealing performance. That seal blocks unfiltered air, while the filter body resists heat and moisture exposure typical in engine bays. The result is consistent protection even in varied driving conditions.

• Polyurethane foam seal prevents bypass and resists heat
• Durable build withstands moisture exposure and vibration
• Cured media keeps pleats stable over service life

Which vehicles is this filter compatible with?

The 5436WS fits a range of Chrysler and Dodge model years but always verify fitment for your specific trim and engine. It’s commonly used on full-size sedans and performance models where a robust filter and steady airflow are priorities.

• Chrysler 300 — model years 2011 through 2023
• Dodge Challenger — model years 2011 through 2023
• Dodge Charger — model years 2011 through 2023
• Confirm exact fit with a vehicle fit checker before purchase

Who is this for? The BOSCH 5436WS is aimed at owners and technicians who want a dependable, workshop-quality air filter that balances strong particle capture with low airflow resistance. It’s a good choice for drivers of compatible Chrysler and Dodge vehicles, performance enthusiasts monitoring intake protection, and maintenance-focused shops that replace filters at regular service intervals to preserve engine condition and efficiency.
