Bosch Engine Air Filter 5436WS for Chrysler 300 & Dodge Challenger/Charger — 98% Efficiency, High-Pleat Seal

The BOSCH 5436WS Workshop Engine Air Filter is a high-pleat, high-efficiency intake filter engineered to capture 98% of small airborne particles and protect your engine.

Replacing a clogged or low-quality engine air filter is one of the simplest ways to preserve engine life, maintain performance, and help fuel economy. The BOSCH 5436WS uses a dense, high-pleat media and a resilient polyurethane seal to balance strong contaminant capture with low airflow restriction, making it a fit-for-purpose option for many Chrysler 300 and Dodge Challenger/Charger model years listed below. These filters are built to resist heat and moisture while maintaining even pleat spacing for consistent filtration performance.

How does this filter reduce engine wear?

The 5436WS traps fine particles before they enter the intake, preventing abrasive dust and debris from contacting internal components. Its cured cellulose media is engineered to hold contaminants in the pleats rather than pass them through, reducing long-term abrasive wear on cylinders and valves.

• 98% efficiency at capturing small particulates
• High-pleat design increases contaminant holding capacity
• Even pleat spacing keeps filtration consistent over time

Will this filter affect my vehicle's airflow or fuel economy?

Bosch balances filtration efficiency with minimal airflow resistance by using high-velocity media; the result is cleaner intake air without significant restriction. When a dirty filter is replaced with the 5436WS, many drivers notice a restoration of throttle response and can see improved fuel efficiency compared with a heavily soiled filter.

• Low-resistance cured cellulose for efficient airflow
• Design aims to restore factory-like intake performance
• Proper sealing prevents unfiltered air bypassing the element

What makes the seal and construction reliable in real-world conditions?

The BOSCH 5436WS uses a polyurethane foam seal that stays elastic across temperature changes, maintaining a tight fit in the airbox. This material also helps block water intrusion and reduces the chance of unfiltered air entering the intake system under demanding conditions.

• Polyurethane foam seal for durable, flexible sealing
• Heat- and moisture-resistant construction for varied climates
• Solid frame and consistent pleat placement prevent collapse or channeling

Which vehicles does this filter fit and how should I verify fitment?

The 5436WS is compatible with many model years of Chrysler 300 and Dodge Challenger/Charger as specified, but fit can vary by trim and engine. Always confirm compatibility using the vehicle fit checker or consult your owner's manual before purchasing to ensure correct fit and performance.

• Compatible examples: Chrysler 300 (2011–2023)
• Compatible examples: Dodge Challenger and Charger (2011–2023)
• Verify by VIN, trim level, or Bosch/retailer fitment tool

Who is this for: The BOSCH 5436WS is aimed at vehicle owners and professional technicians who want a direct replacement air filter that prioritizes particle control and durable sealing. It's a practical choice for drivers of compatible Chrysler and Dodge models who seek to restore intake protection and maintain engine performance without altering factory airflow characteristics.
