Hybrid Racing Water Pump Port Block Off for K20A2/K20Z
Hybrid Racing Water Pump Port Block Off Fitting - K20A2, K20Z1 & K20Z3
Pull the factory oil cooler setup off a K20A2, K20Z1, or K20Z3 and you're left with an open port on the water pump that has to be sealed. This is the fitting that does it. It fills the oil cooler port cleanly and permanently, so you can delete the factory cooler or run a custom setup that doesn't use the sandwich plate, without ending up with a coolant leak where that hose used to be.
Two situations bring people here, and both are common on built engines.
The first is a straight oil cooler delete. Plenty of builds don't need the factory oil cooler, especially swaps where the sandwich plate and its plumbing are just complexity you'd rather not carry. Pull it off, block the port, done.
The second is a custom oil cooling setup that doesn't use the factory sandwich plate on the back of the engine. If you've gone to a proper remote cooler with its own plumbing, the water pump's oil cooler port isn't part of that circuit anymore. Blocking it off is how you close out the factory system and keep everything sealed.
Either way, this is the small part that finishes the job properly instead of leaving you improvising with a plug that wasn't made for it.
