Vehicle / Engine Applications: 02-06 RSX Type-S + Type-R K20A/A2/Z1 (PRB head), 02-06 RSX Base K20A3 (PNC head), 02-05 Civic Si (PNL head), 02-06 CRV K24A1 (PPA head), 88-00 Civic / 90-01 Integra K-swaps using any of these cylinder heads.
The recently updated simple version of Tractuff's upper water neck for PRB/ PRC/ PPA cylinder heads is now on the shelf! The new changes include a raised lip that serves as an o-ring seat for those that want to use the NEW -16 ORB threads for either a hose barb or AN fitting or as a generous spot for a fillet weld (for those that want to fabricate something custom). The flange now has counter sunk M6 socket head bolt holes for that finished look and still has the OEM o-ring grove for a positive seal!
The flange still has space just above the port to drill and tap for a pressure transducer or coolant temp sensor if needed.
