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.\u003c\/p\u003e\n\n\u003ch4\u003eWhen You Need One\u003c\/h4\u003e\n\n\u003cp\u003eTwo situations bring people here, and both are common on built engines.\u003c\/p\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003cp\u003eEither 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.\u003c\/p\u003e\n\n\u003ch4\u003eDo It Right, Not With Whatever's In The Drawer\u003c\/h4\u003e\n\n\u003cp\u003eIt's tempting to jam something generic in there and move on, but this port is on the coolant side of the water pump, so whatever seals it needs to actually hold. A leak here isn't a minor annoyance, it's coolant loss somewhere you may not spot right away. This fitting is made for that specific port, so it seats correctly and seals the way it should. It's cheap, it's the right part, and it means you never think about that hole again.\u003c\/p\u003e\n\n\u003ch4\u003eWorks In FWD Or RWD Swaps\u003c\/h4\u003e\n\n\u003cp\u003eBecause it threads into the water pump rather than mounting to anything on the chassis, this works the same in any application. Original car, front-wheel-drive swap, or a rear-wheel-drive conversion, if you're running one of these three engines and you're not using the factory oil cooler circuit, this closes it out. RWD builders in particular tend to end up here, since those swaps often ditch the factory cooler arrangement entirely in the name of packaging.\u003c\/p\u003e\n\n\u003ch4\u003eFits These K-Series Engines\u003c\/h4\u003e\n\n\u003ctable\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth scope=\"col\"\u003eEngine\u003c\/th\u003e\n            \u003cth scope=\"col\"\u003eOriginally Found In\u003c\/th\u003e\n            \u003cth scope=\"col\"\u003eYears\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n\u003ctd\u003eK20A2 \/ K20Z1\u003c\/td\u003e\n\u003ctd\u003eAcura RSX Type-S\u003c\/td\u003e\n\u003ctd\u003e2002-2006\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003eK20Z3\u003c\/td\u003e\n\u003ctd\u003eHonda Civic Si\u003c\/td\u003e\n\u003ctd\u003e2006-2011\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eAll three engines share the water pump with the factory oil cooler port, so this fitting works across every one of them, in the original chassis or in a swap.\u003c\/p\u003e\n\n\u003ch4\u003eKeeping Your Oil Cooler Instead?\u003c\/h4\u003e\n\n\u003cp\u003eIf you're not deleting the circuit and you just want to convert that port to AN line for a custom oil cooler, you want our \u003ca href=\"#\"\u003e-6AN water pump port fitting\u003c\/a\u003e instead.
