K&N Engineering Airforce Pre-Cleaner Foam Wrap * Red for Round Straight Air Filters
Description

The K&N Engineering Part Number knn25-3750 Airforce Pre-Cleaner is a high-performance foam filter wrap designed to enhance the longevity of your K&N air filter in extremely dusty environments. Made from large, open-cell foam, this pre-cleaner effectively captures dirt and debris before they reach your primary filter, reducing maintenance frequency and extending service intervals. The red-colored pre-cleaner is pre-oiled with K&N air filter oil after cleaning, ensuring optimal filtration efficiency, while the gray version uses smaller foam cells and does not come pre-oiled, providing flexibility based on your application needs. This versatile foam wrap is suitable for round, straight air filters and is easy to install, offering a reliable solution for off-road vehicles, heavy-duty equipment, or any application exposed to high dust levels. Built to withstand demanding conditions, the Airforce Pre-Cleaner maintains airflow while trapping large particles, helping to keep your engine cleaner and operating efficiently for longer periods.

Features:

  • Designed to extend service intervals of K&N air filters in dusty conditions
  • Constructed from large, open-cell foam for effective dirt capture
  • Pre-oiled red version for immediate use and enhanced filtration
  • Gray pre-cleaner with smaller foam cells for different filtration needs
  • Suitable for round, straight air filters with easy installation
