GM EGR plug PN change? Discontinued?
According to the search the GM PN for this is 12558346. This PN shows up on some GM dealers but it's always unavailable? Is there a new PN or is it just discontinued?
This will be a heavily boosted setup. Think I'd be better off with an expandable plug or a solid brass freeze plug JB welded in place?
Thanks
