Assure your cooling system is on point and leak free by replacing ke components with a JDM oem part like this one. Over time heat and corrosion can deteriate these waternecks. Replace yours today and save yourself a future headache.
**Note:S13 SR20DET users can upgrade to this water neck and run their turbo water inlet line directly to the water neck instead of the rear of the engine, which may be difficult to get to.
S14 Turbo Lines are required if use with S13 SR20DET.
