This is the newest offering it comes with Stainless Steel braided Teflon lined hoses.
See video below for more info.
Note: this is a Hose and fittings kit only for reusing the original GM cooler, the oil cooler is not included. Look at this listing if you want a kit with a new oil cooler
In an effort to insure you get everything you need you can now buy extra block fittings with 3/8″ npt (the kit already comes with 1/2″ npt fittings). If you are unsure what size block fittings you need for an extra $14 you can buy both by adding these to your cart. (note there are no returns/refunds allowed on these).
