Gates Integra Radiator Hoses Upper and Lower
Your 94-01 Integra has been cooking the same radiator hoses for a couple of decades. When the lower hose goes soft or the upper hose cracks, you smell coolant, you find a puddle, and your B18 starts climbing temp on the drive home. Gates 22703 is the molded lower hose. Gates 22920 is the preferred molded upper for GS, LS, and GS-R. Both are EPDM. They're not a silicone kit. You pick one position per order. DC2 chassis. B18B1, B18C1, and B18C5.
What It Is and Why It Works
You're buying one hose, not a pair in a box. 22703 is the lower. 22920 is the upper. RockAuto calls 22920 the preferred upper for GS, LS, and GS-R, and it supersedes OEM 19501-P72-000. 22703 is the lower, OEM 19502-P72-000. Clamps aren't in the bag. If both hoses are original, you're going to want both, but you still order them one at a time.
It's EPDM tube and cover with a synthetic fiber knit. That's the Gates molded coolant hose recipe, and it's built to fight electrochemical degradation, the galvanic attack that opens micro-cracks in old rubber. Per manufacturer, the line is rated from -40 F to 275 F. This hose won't look like a silicone dress-up kit, and it won't buy you extra intake room. It just puts the right-shape rubber back on a tired DC2.
Type R upper fitment is messy. Some catalogs keep 22920 on Type R. RockAuto lists Gates 22413 as the Type R upper. If you're on a B18C5, look at the hose you're pulling before you click Upper. The lower, 22703, is the generation lower hose.

Fitment
| Year | Make | Model | Trim | Engine |
| 1994-2001 | Acura | Integra | RS, LS, GS, GS-R, Special Edition | B18B1 / B18C1, DC2 |
| 1997-1998, 2000-2001 | Acura | Integra | Type R | B18C5, DC2 |
This doesn't fit a 1990-1993 DA Integra, an 02-06 RSX, a 94-01 Civic, or a K-swap unless you kept the Integra radiator and housing. There's no 1999 US Type R. RockAuto lists 22920 as the preferred upper for GS, LS, and GS-R, and lists Gates 22413 as the Type R upper. Confirm the hose on a B18C5 before you click Upper.
What to Know Before You Buy
A molded radiator hose isn't a silicone kit. You'll still need clamps, coolant, and a system that holds pressure. Gates tells you to replace the clamps with the hose. If both hoses are original, replace both. 22703 won't fix a bad radiator or a stuck thermostat.
