PHR - Powerhouse Racing Stainless Freeze Plug Set for Toyota 1JZ / 2JZ Engine Block

Leaky freeze plugs can be a serious pain in the ass on brand new builds.

If you are building a motor, you know cleaning the coolant passages decently requires removal of the factory freeze plugs. Reinstalling the stamped steel Dorman or OEM plugs sucks. Even being very careful they easily warp or damage edges of the holes. And there is nothing worse than having to pull apart a brand new build to repair a stupid freeze plug.

These new billet freeze plugs eliminate that problem. They have an aligning minor diameter to square up the plug for the initial press start. Then press in easily and firmly by simply tapping them in with a hammer. There is a shoulder on the outside edge that you can apply FIPG or silicone to to ensure it will be perfectly sealed even beyond the press seal, and the should assures it to be installed perfectly square at at the perfect depth.

Not to mention, they are threaded in the center to be easily removed for block cleaning and are totally reusable and transferable to a different block.
