Product Details

The Pioneer Automotive PE817R is a complete engine expansion plug kit designed to seal core holes in engine blocks, cylinder heads, and other powertrain components. These plugs — commonly referred to as freeze plugs, core plugs, or Welsh plugs — are pressed or driven into machined openings left over from the casting process, preventing coolant leaks and maintaining proper engine cooling system integrity.

Key Features:

  • Complete kit providing multiple expansion plugs for a full engine service
  • Manufactured to meet or exceed OEM specifications for a precise, leak-free fit
  • Constructed from quality steel for durability and corrosion resistance
  • Designed for easy installation using standard plug-driving tools
  • Ideal for engine rebuilds, overhauls, and cooling system repairs

Pioneer Automotive has been a trusted manufacturer of engine sealing products, gaskets, and related components for decades. The PE817R kit is well-suited for professional rebuilders and experienced DIY mechanics performing engine restoration or overhaul work. Always verify plug diameter and depth against your specific application before installation.

These people are just awesome! I got my Thule Bike Rack for a fraction of the cost compared to everywhere else. Shipping was very fast and cheap but when I received it there were a couple of missing hardware parts. Thule wanted to make me ship the whole thing back. Rob Fratu of Autoplicity took control of the situation and got Thule to ship me the missing parts and some extras, all within a couple of days. I cant remember a better experience with a retailer.

Very quick ordering, however I was unable to use the PayPal function.

Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

They had what I needed, No hassle ordering. and it shipped fast.

Great price, good e-mail communication and fast shipping. Positive experience with Autoplicity so far.

Easy to use web site. Quickly found what I needed. Smooth check out and SUPER FAST delivery. Couldn't ask for a better transaction experience. Bookmarked and for sure "GO TO" for next auto parts search. Thanks Autoplicity

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!

Great store! Best prices, fast fedex shipping. Very satisfied, will buy from Autoplicity again!

quick shipping

Wow super fast shipping and I ordered over a holiday weekend. Will be doing business with this site again soon.
