Boost airflow, enhance throttle response, and enjoy a washable, lifetime filter.The K&N 04 BMW 545i 4.4L V8 Drop In Air Filter is a high-flow replacement engineered to improve airflow and engine performance while keeping out harmful dust and road debris.

The K&N High-Flow Drop-In Engine Air Filter (Part # 33-2294) is custom-designed for the 2004 BMW 545i 4.4L V8 engine. Constructed with 4 layers of oiled cotton gauze media held in place by an epoxy-coated aluminum mesh, it provides up to 50% more airflow compared to standard paper filters without sacrificing filtration efficiency.

This filter arrives pre-oiled and drops directly into your factory BMW airbox without requiring modifications or special tools.

  2. Performance Upgrades: Enhances airflow to complement other intake or exhaust modifications on the 4.4L V8.

  2. Direct Drop-In Fit: Specially contoured frame drops straight into the OEM factory airbox with no extra hardware needed.
  3. Washable & Reusable: Designed to be cleaned and re-oiled for repeated use throughout the vehicle's lifespan.
  4. Extended Maintenance Interval: Requires service only every 50,000 to 75,000 miles under normal highway driving conditions.
  5. Durable Urethane Frame: Constructed with a rugged, molded frame and coated aluminum wire mesh for structural stability.

Benefits

  1. Improved Airflow: Delivers up to 50% more air to the engine, helping improve combustion efficiency and throttle response.
  2. Long-Term Cost Savings: Eliminates the need to repeatedly purchase disposable replacement filters over time.
  3. Engine Protection: Traps up to 99% of dust and dirt particles to safeguard internal engine components.
