It's common for the plugs to fall out, lose coolant externally or even internally into the oil. Unfortunately, most of the freeze plugs are located behind the timing cover and valve covers, so you would never know if they popped out. This can happen on OEM cars as well as cars with performance upgrades causing a number issues that could be catastrophic.\u003c\/p\u003e  \u003cp\u003eTo solve the issue, the failure prone pressed-in freeze plugs are removed from the cylinder heads and threaded plugs are added in place. IAG provides the threaded plug upgrade on all of our FA cylinder head packages. In order to install the plugs IAG machine threads into (x4) freeze plug locations on each cylinder head. IAG offers the machine service separately (Service# IAG-MSS-2920).\u003c\/p\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e(x8) Threaded zinc plated plugs  \u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e \u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eInstall Recommendations:\u003c\/strong\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003eHeads must be removed from the long block and require machine threading\u003c\/li\u003e \t\u003cli\u003eProfessional Machining Services Required\u003c\/li\u003e \t\u003cli\u003eProfessional Install Recommended\u003c\/li\u003e \t\u003cli\u003eLoctite 577 is required for install (Not Included)\u003c\/li\u003e \t\u003cli\u003ePlugs should be torqued to 55 N.m\u003c\/li\u003e \u003c\/ul\u003e \u003ca href=\"https:\/\/www.prospeedracing.com.au\/IAG-Performance-Cylinder-Head-Threaded-Plug-Set-of-8-Subaru-WRX-VA-BRZ-Toyota-86-FA20-IAG-ENG-2020\" style=\"text-decoration:none\"\u003e \u003c\/a\u003e","brand":"IAG Performance","offers":[{"title":"Default Title","offer_id":49201434722607,"sku":"IAG-ENG-2020","price":259.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/IAG-ENG-2020.jpg?v=1712727266","url":"https:\/\/www.prospeedracing.com.au\/products\/iag-performance-cylinder-head-threaded-plug-set-of-8-subaru-wrx-va-brz-toyota-86-fa20-iag-eng-2020","provider":"Pro Speed Racing","version":"1.0","type":"link"}
