Product Details

The Pioneer Automotive PE300B is a professional-grade engine expansion plug kit designed to seal core holes in engine blocks, cylinder heads, and other castings. Also commonly referred to as freeze plugs, core plugs, or Welsh plugs, these components play a critical role in preventing coolant leaks and protecting engine internals from corrosion and pressure loss.

Key Features:

  • Complete kit containing multiple expansion plugs for comprehensive engine sealing
  • Manufactured to OEM specifications for precise, reliable fitment
  • Constructed from high-quality steel for durability and corrosion resistance
  • Seals engine block core holes left over from the casting manufacturing process
  • Helps maintain proper coolant system pressure and prevents leaks
  • Suitable for use during engine rebuilds, overhauls, and repairs

Pioneer Automotive has been a trusted name in the automotive parts industry since 1946, supplying quality engine components to the remanufacturing and repair markets. The PE300B expansion plug kit delivers the reliability and precision fitment that professional rebuilders and repair technicians demand.

Thank you foryou fast service, and knowledge. I will definitely be shopping again for my automotive supply needs.

super service and best price on the net

Im really pleased with the order process and will be ordering from them again

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Thanks for the great service, best prices, and fast shipping!!!

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.
