Peterbilt Fresh Air Pre-Filter

The Peterbilt Fresh Air Pre-Filter is a practical and efficient solution for improving the performance of any exposed air filter. Made of 1/8 inch thick ABS plastic, this pre-filter features a proprietary polyester mesh with uniform micron openings that filters debris down to 0.005 inches. It is treated with a hydrophobic water-repellant process, making it resistant to water and UV rays. With its shatter-proof and puncture-resistant design, this pre-filter is suitable for freezing temperatures and can withstand heat up to 450 degrees Fahrenheit. Its elastic mesh ensures it returns to its original position even after impact or shifting. Designed to fit most Peterbilt 377, 378, 379, 386, 388, and 389 series trucks, it installs on the passenger side exterior, making it a practical choice for those with external air cleaners.
