PRODUCT DETAILS
TracTuff Water Bypass Block Off – K20Z3 / K24A2 / K24A4 / K24A8
The TracTuff Water Bypass Block Off is designed for enthusiasts running the K20Z3 and K24A-series engines found in the 2006–2011 Honda Civic Si and 2004–2008 Acura TSX. Built for those who want a simple, effective way to delete the factory water bypass, this precision-machined block off provides a clean and functional solution without unnecessary complexity or cost.
This product was developed after years of customer feedback surrounding the original TracTuff Water Bypass Adapter. Many users were simply plugging the adapter rather than routing coolant through it. To better serve those builds, TracTuff created a dedicated block-off plate that retains all the fitment precision and quality of the adapter, without the added expense of unused features.
Each block-off is machined from high-quality aluminum for strength and durability, featuring the same attention to detail that defines every TracTuff component. It installs cleanly and maintains a factory-like appearance while removing the need for additional fittings or hoses. While this part allows you to simplify your cooling setup, it’s important to understand that the water bypass serves a functional role in engine temperature management. Research the pros and cons of this modification to ensure it aligns with your build goals.
Note: If you plan to add a sensor port, drill and tap from the front side for your sensor’s thread pitch. Do not start tapping from the back.
