Spoon Sports Radiator Hose Set

Spoon Sports Radiator Hose Set - S2000, Integra, RSX & Civic

Your factory radiator hoses are rubber, and rubber has a lifespan. It swells when the bay gets hot, softens over years of heat cycling, and eventually loses enough structure that the upper hose can collapse under vacuum as the system cools. On cars that are now decades old, the originals are well past their prime. Spoon's answer is a thick-walled SEP hose set molded specifically for each chassis, built to hold its shape when things get hot.

SEP, Not Silicone

Worth being clear about the material, since a lot of people assume any upgraded hose is silicone.

These are ethylene propylene, thick-walled, with older Spoon documentation rating them to 160°C. The reason for that choice over silicone is collapse resistance: a thick EP wall holds its shape under the pressure and vacuum swings a cooling system goes through, which is exactly where tired factory rubber gives up.

The practical consequence is that you don't get color options the way you would with silicone. These are what they are, and they're chosen for how they behave rather than how they photograph.

Molded Per Chassis

Each set is molded for its specific application rather than being a universal hose cut to length. That means the bends are where they should be, the routing follows the factory path, and you're not fighting a hose into position or worrying about it contacting something it shouldn't. That's also why the applications aren't interchangeable, which brings us to the important part.

Get Your Chassis Code Right

Read this carefully, because several of these look similar in a dropdown and are not the same part.

FK7 and FK8 are different. One is the 10th-gen hatchback, the other is the Type R, same generation, different hose.

FL1 and FL5 are different. Same situation on the 11th gen. The FL1 is not a Type R.

The FD2 hose is for the FD2 Type R, the JDM sedan, not the USDM FG2 Si.

The EK9 hose covers the EK4 and EK9 specifically, not every 1996-2000 Civic.

And one fitment note on the 10th gen: the FK7 hose is listed for the hatchback. If you've got the FC1 sedan Si, confirm before ordering rather than assuming it's covered.

Don't Wipe The Logo

Small thing that catches people out. The Spoon mark is printed on the hose, and it will rub off if you wipe or scrub over it during installation.

So when you're routing them and cleaning up coolant, work around the printing rather than over it. It's the kind of detail you only get told once, usually after somebody's already erased half of it with a shop rag.

Do The Job Properly

You're draining the cooling system anyway, so make the most of it.

Replace tired clamps while you're in there, a new hose on a corroded clamp that won't hold tension is a leak waiting to happen, and clamps cost almost nothing. Bleed the system properly when you're done, air pockets in a Honda cooling system cause overheating that looks like a much bigger problem than it is, so take the time to get it right. And while you've got the coolant out, it's a sensible moment to look at your radiator cap, thermostat, and anything else rubber in the system, two-decade-old parts tend to fail in groups.

Fitment

Chassis codes are not interchangeable, select your exact application:

2000-2009 Honda S2000 (AP1/AP2)
1994-2001 Acura Integra GS-R and Type R (DC2/DB8)
2002-2006 Acura RSX Type-S (DC5R)
1992-1995 Honda Civic Si/SiR (EG6/EG9)
1996-2000 Honda Civic SiR/Type R (EK4/EK9)
2002-2005 Honda Civic Si (EP3)
2007-2011 Honda Civic Type R (FD2)
2017-2021 Honda Civic Hatchback (FK7)
2017-2021 Honda Civic Type R (FK8)
2022-2026 Honda Civic (FL1/FL1 RS)
2023-2026 Honda Civic Type R (FL5)

This is for the owner replacing hoses that have earned their retirement, and for anyone building a car where the cooling system should be as sorted as everything else. On an older Honda it's overdue maintenance done properly rather than with whatever the parts store had; on a newer one it's a Spoon detail in a spot that matters. Match your chassis code exactly (several look alike and aren't interchangeable), replace your clamps, bleed it properly, and stop thinking about your hoses.

Material: thick-walled SEP (ethylene propylene), heat resistant to 160°C (per older Spoon documentation). Type: chassis-specific molded upper and lower radiator hose set. Chosen for: collapse resistance under pressure and vacuum, where rubber fails. Applications: S2000, Integra, RSX, and multiple Civic chassis (see fitment list). Note: chassis codes are not interchangeable, confirm yours; the printed Spoon logo can rub off, avoid wiping over it during install. No color options (SEP, not silicone).
