TCS Gen4 & Gen5 Water Neck Modification

This modification is for the Gen4 & Gen5 3SGTE engine ONLY. When you swap a Gen4/5 3SGTE into your MR2, you also have to track down a hard to find Gen3 water neck in order to finish your swap! We take the existing Gen4/5 water neck and modify it to retain your factory coolant cap, all the while really cleaning up your engine bay! PLEASE NOTE: This price assumes that you will be sending us your Gen4/5 water neck to be modified. These cores are rare, so we require you to send us yours after you place your order. Turn around time is typically 2-3 business days.
