Improve the exterior of your Peterbilt with these 16.25-inch stainless steel blank front air cleaner panels designed for trucks equipped with 15-inch breather systems. Built from durable 430 stainless steel, these aftermarket panels are made to fit select Peterbilt 378 and 379 models and provide full coverage across the front air cleaner area. Their blank design delivers a smooth, minimal appearance that pairs well with both restoration builds and custom exterior styling. Sold as a pair, the panels are designed for straightforward installation and are intended for heavy-duty applications. The polished stainless steel finish helps resist corrosion while maintaining a clean, consistent look alongside other exterior trim components. Made for compatibility with common Donaldson or Vortox 15-inch breather setups, these panels offer a practical way to refresh the truck's front-end appearance without altering core functionality.
