Fits Honda / Acura B,D,F,H,J, and K-Series Engines! Whether utilizing one of our Street Series Cooling System Fill Pots, installing VTEC-Eliminating racing camshafts, or for aftermarket component clearance there are many reasons people rid their engine setups of the VTEC Oil Pressure Switch. Our ultralight, hollow-domed 6-point VTEC Oil Pressure Switch Delete bolts are machined from Ti-6Al-4V Titanium and are available in raw and burnt finishes. Each kit includes (1) bolt in finish of your choice. Simply remove your VTEC Oil Pressure Switch (If equipped) and install this bolt, re-using your factory O-Ring. Please see OBD1 wiring notes below if necessary. Wiring: Many common OBD1 and OBD2 JDM engines do not have a VTEC Oil Pressure Switch. The corresponding JDM ECUs for these engines do not use the pressure switch, so this will not be an issue. However, when using a USDM ECU on a JDM or USDM engine that does not have a VTEC Oil Pressure Switch, you will encounter a problem with VTEC not engaging because the USDM ECU will not be receiving the signal from the VTEC Pressure Switch. The VTEC Oil Pressure Switch Wiring can be easily bypassed as follows: 1) Locate the VTEC Oil Pressure Switch Plug on your engine harness (this wire comes from OBD1 ECU Pin D6). 2) Simply TAP this wire into the VTEC Solenoid Valve Wire (the VTEC solenoid wire comes from OBD1 ECU Pin A4). **Do not cut the VTEC Solenoid Wire (A4), simply connect the VTEC Pressure Switch wire to it. 3) Your ECU will now believe that it has a VTEC Oil Pressure Switch connected and your VTEC will now function properly.
