This Mishimoto kit replaces them with black silicone reinforced with heat-resistant fibers, rated to 330°F, hoses that won't degrade the way the old rubber has. Available for D-series or B-series setups.\u003c\/p\u003e\n\n\u003ch4\u003ePick Your Setup: D-Series Or B-Series\u003c\/h4\u003e\n\n\u003cp\u003eThe EF came with D-series engines, but a lot of them now run B-series swaps, so the kit comes in two fitments. Match yours before ordering.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eD-series (MMHOSE-CIV-88)\u003c\/strong\u003e is for the factory D-series setup (and D-series swaps). One important note: the D-series kit's \u003cstrong\u003eupper hose fits SOHC engines only\u003c\/strong\u003e, so confirm you're running a SOHC D-series before ordering this version.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eB-series (MMHOSE-CIV-88B16)\u003c\/strong\u003e is for a B16 or other B-series swap, routed for the B-series engine's cooling connections rather than the factory D-series layout.\u003c\/p\u003e\n\n\u003cp\u003eGo by what's actually in the car, not what it came with, since a swapped EF needs the kit that matches its current engine, not its original one.\u003c\/p\u003e\n\n\u003ch4\u003eWhy Silicone Beats Old Rubber\u003c\/h4\u003e\n\n\u003cp\u003eWorth understanding, because on a car this age it's not a question of if the rubber fails, but when.\u003c\/p\u003e\n\n\u003cp\u003eRubber coolant hoses degrade from the inside out. Heat cycles dry them out, they crack and get brittle, and pressure makes them balloon and weaken. On a factory hose that's been on the car for three decades, that failure is overdue, and it tends to happen under heat and load, exactly when you're driving the car hard or far from home.\u003c\/p\u003e\n\n\u003cp\u003eSilicone doesn't have that failure mode. It handles heat and pressure far better, it doesn't dry out or crack, and it doesn't balloon, so the connection stays tight and reliable. These are built from high-grade silicone with \u003cstrong\u003eheat-resistant embedded fibers\u003c\/strong\u003e, rated to \u003cstrong\u003e330°F\u003c\/strong\u003e and with greater pressure tolerance than the factory rubber. Fit them once and stop worrying about the aging hoses.\u003c\/p\u003e\n\n\u003ch4\u003eHeads Up: Clamps Not Included\u003c\/h4\u003e\n\n\u003cp\u003eImportant so you order everything you need in one go.\u003c\/p\u003e\n\n\u003cp\u003eThis kit is the \u003cstrong\u003eradiator hoses only\u003c\/strong\u003e, no T-bolt or worm-gear clamps are included. You'll need clamps to install them, so if you don't have good reusable ones, add a set to your order so you're not stopped partway through the job. It's an easy thing to overlook and a frustrating one to discover mid-install.\u003c\/p\u003e\n\n\u003ch4\u003ePair It With The Radiator\u003c\/h4\u003e\n\n\u003cp\u003eThe natural companion for a complete cooling system.\u003c\/p\u003e\n\n\u003cp\u003eThese hoses pair with the \u003ca href=\"https:\/\/www.hybrid-racing.com\/products\/mishimoto-aluminum-radiator-ef-civic-crx\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eMishimoto aluminum radiator\u003c\/a\u003e for the EF Civic and CRX. The radiator adds cooling capacity; the silicone hoses replace the failing factory rubber with material that holds up to heat and pressure. Doing both while the cooling system is open is the efficient way to refresh it, and together with the fan shroud they're the full cooling upgrade for these cars. The hoses also work fine on a stock radiator if you're just replacing the tired rubber.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e1988-1991 Honda Civic and CRX\u003c\/p\u003e\n\n\u003cp\u003eD-series (MMHOSE-CIV-88, SOHC upper hose) or B-series (MMHOSE-CIV-88B16, B16 swap).
