Similar to the modified water necks on the Gen4 3SGTE we have been doing for some time now, this is a factory 2GR water neck with a water neck and sensor port welded onto it to make 2GR the cooling system work in the MR2. The 2GR utilizes a radiator cap on the radiator in the factory Rav4, Sienna, and Highlander applications. With this not a possibility on the MR2's this is the easiest way to get the cooling system ready to roll in your MR2. An added bonus with this water neck is the relocation of the radiator cap to the water neck itself, which cleans up your engine bay and makes things a little simpler, with fewer hoses to leak.
*When purchasing, you must send your factory 2GR water neck to us as a core
