On the K20Z3, the oil cooler hoses carry oil to and from the cooler, and they're EPDM rubber, which means they live a hard life. Constant heat cycling, engine bay temperatures, and years of flexing eventually take their toll, and a tired hose either seeps, cracks, or lets go at the worst possible time. These are the genuine Honda replacements, and they're sold individually, so you can replace just the one that's leaking without paying for both.\u003c\/p\u003e\n\n\u003ch4\u003eWhich Hose Do You Need?\u003c\/h4\u003e\n\n\u003cp\u003eThis is the important part, since you're buying them separately, and telling them apart is easy once you know what you're looking at. The two hoses are shaped differently, so identify the one that's leaking and order that part number.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003einlet hose (19422-RRB-A01)\u003c\/strong\u003e is the U-shaped one. It has the tighter bend that curves back on itself, so if the leaker is the short, sharply curved hose, that's the inlet.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eoutlet hose (19423-RRB-A01)\u003c\/strong\u003e is the longer, straighter one. It runs with a much gentler shape, so if you're looking at the long hose without the tight U bend, that's the outlet.\u003c\/p\u003e\n\n\u003cp\u003eTrace the wet hose back to figure out which one has gone, match it to the shape, and order that part number. If both are old and seeping, or you'd just rather do it all at once on a car this age, grab both and be done with it.\u003c\/p\u003e\n\n\u003ch4\u003eWhy Genuine Honda Is The Move Here\u003c\/h4\u003e\n\n\u003cp\u003eThis is an oil line, so this isn't the place to gamble on a cheap universal hose. These are the exact EPDM rubber hoses Honda spec'd for the K20Z3, shaped to route correctly and sized to seal at the factory connections without fighting them. OEM rubber holds up to the heat and the vacuum conditions in the engine bay the way a generic hose won't, and it fits right the first time so you're not wrestling it into place or worrying about a connection that doesn't seat properly. On something carrying your engine's oil, correct and reliable beats cheap every time.\u003c\/p\u003e\n\n\u003ch4\u003eDo Both While You're In There?\u003c\/h4\u003e\n\n\u003cp\u003eWorth thinking about. If one hose has aged out on a 15-plus-year-old Si, the other one usually isn't far behind. Replacing just the leaker is the cheaper fix and totally reasonable, but if you're already in there and the second hose is original and tired, doing both now saves you a repeat trip under the car in a few months. Your call based on what shape the other hose is in.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003eThese fit the K20Z3 engine found in the 2006-2011 Honda Civic Si, both the coupe and the sedan. If you're running a K20Z3, whether it's still in an Si or it's gone into a swap, these are the correct oil cooler hoses for that engine.\u003c\/p\u003e\n\n\u003ch4\u003eWho This Is For\u003c\/h4\u003e\n\n\u003cp\u003eThis is for the Si owner chasing down an oil leak, doing preventive maintenance on a high-mileage car, or freshening up an engine during a build or a swap. Old rubber is old rubber, and oil cooler hoses are one of those wear items worth replacing before they fail rather than after. Figure out which one you need, or grab both, and stop worrying about that line.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e Honda K20Z3, 2006-2011 Honda Civic Si (coupe and sedan), plus K20Z3 swaps. \u003cstrong\u003eSold individually:\u003c\/strong\u003e inlet hose (19422-RRB-A01, U-shaped) and outlet hose (19423-RRB-A01, longer and straighter). \u003cstrong\u003eMaterial:\u003c\/strong\u003e genuine Honda EPDM rubber. \u003cstrong\u003eType:\u003c\/strong\u003e OEM replacement oil cooler hoses.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003e2007-2011 Honda Civic Si\u003c\/p\u003e \n\u003c\/li\u003e\n\n\n\n\n\n\n \n\u003cli id=\"Included\"\u003e\n\u003cp\u003e(1) Inlet Hose*\u003cbr\u003e(1) Outlet Hose*\u003cbr\u003e\u003cem\u003e*Sold Individually\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"Honda","offers":[{"title":"Inlet","offer_id":46099086901282,"sku":"OHA-19422-RRB-A01","price":11.39,"currency_code":"USD","in_stock":false},{"title":"Outlet","offer_id":46099086934050,"sku":"OHA-19423-RRB-A01","price":13.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/honda-k20z3-oil-cooler-hoses_u2xs.jpg?v=1784923531","url":"https:\/\/www.hybrid-racing.com\/products\/honda-k20z3-oil-cooler-hoses-19422-rrb-a01","provider":"Hybrid Racing","version":"1.0","type":"link"}
