Product Details

The Stainless Works HF4.6 header flanges are precision-engineered exhaust flanges designed specifically for Ford 4.6L 32-valve engines, including 2003-2004 Cobra applications. These flanges are laser-cut to accommodate the wide oval port configuration found on these high-performance engines.

Key Features:

  • Sold as a pair for complete left and right side installation
  • Designed for 1-3/4 inch diameter primary tubes
  • Laser-cut from heavy-duty 3/8 inch thick 304 stainless steel
  • Superior resistance to warping under high exhaust temperatures
  • Wide oval port pattern matches Ford 4.6L 32-valve cylinder heads
  • Backed by Stainless Works limited lifetime warranty

The extra-thick 3/8 inch construction ensures a flat, leak-free seal even after repeated heat cycles, making these flanges ideal for custom header fabrication or header repair projects. The 304 stainless steel material provides excellent corrosion resistance and longevity in harsh exhaust environments.
