Product Details

The Pioneer Automotive PE109 is a complete engine expansion plug kit specifically designed for Ford 400 cubic inch (6.6L) V8 engines. Also known as freeze plugs or core plugs, these essential components seal the casting holes created during engine block manufacturing and help prevent catastrophic engine block damage in freezing conditions.

Key Features:

  • Complete plug kit with all necessary sizes for one Ford 400 engine block
  • Engineered to OEM specifications for precise fit and reliable sealing
  • Prevents coolant leaks and protects against freeze damage
  • Designed for Ford 351M and 400 engines (1971-1982)
  • Steel construction for durability and long service life

Expansion plugs are critical wear items that can corrode over time, leading to coolant leaks and potential engine damage. The PE109 kit provides everything needed for a complete refresh during engine rebuilds, restoration projects, or when replacing leaking plugs. Pioneer Automotive is a trusted name in engine components, offering quality replacement parts for professional mechanics and DIY enthusiasts.

Always the parts I need in stock

Great price and reads up to 300lbs just what I needed. Thanks

I knew what I wanted, yet you don't provide much info on this product. You might make more sales if you informed the consumer of the part details.

Everything was fine, but your order page would not let me chose to pay with paypal yesterday. It worked today.

Ordered a product and received within 2 days. Easy transaction and quick delivery.

Wow, first time I ordered and they hit a homerun with me!! Shipped same day I ordered AND was the cheapest option I had including shipping. I'll be back. Thanks for the great service!!
