Spoon Sports Oil Filler Cap (ALL-15610-001)
Some brands you buy because of what the part does. Spoon you buy because of what it means. Since the 80s they've been the name people point to when they talk about Hondas done right, blue and yellow race cars, engines built to a standard nobody else bothered with, and a catalog full of parts that look like they belong on something serious. This billet aluminum oil filler cap is one of the cheapest ways to put that on your car.
The Entry Point To A Spoon Bay
Here's why these are so popular. Most Spoon parts are a real commitment, a header, a clutch, suspension, an ECU. Nobody starts there. What people start with are the small pieces: the oil cap, the reservoir cover, the radiator cap. Cheap enough to grab on impulse, visible every time the hood goes up, and unmistakably Spoon to anyone who knows the brand.
An aluminum Spoon cap sitting on your valve cover changes how the bay reads. It's a signal that the person who built the car knows the history and cares about the details, and that's worth more in this community than most parts costing ten times as much.
Why The Blue Matters
Spoon's blue and yellow comes off their race cars, not a marketing meeting. That livery has been on Hondas at circuits around the world for decades, long enough that the color alone identifies the brand without anyone reading a logo. It's why Spoon pieces look right together and why people build entire bays around them.
Add one piece and it stands on its own. Add a few and they start looking like a theme, which is exactly how most Spoon bays get built, one part at a time.
It's Aluminum, And That's Not Just For Looks
Spoon is direct about this: the cap isn't purely cosmetic. It's machined from aluminum, which means it handles the heat cycling and vibration that eventually makes factory plastic caps brittle and crack. So while you're buying it for the badge, you're also getting a piece that outlasts what it replaces.
Check Your Filler Neck First
One thing to confirm before you order, and it takes ten seconds. This is a screw-in cap with M33 x P3.5 threads, which is what Honda has used across most of their lineup for decades.
What matters isn't the badge on your car, it's how your current cap comes off. If it unscrews, you're almost certainly fine. If it pops or twists off with a cam lock, this won't fit, because that's a different filler design entirely.
So go pop your hood and turn your cap. That's the whole check.
Fitting It
Hand-tight is enough. Aluminum onto an aluminum or plastic head will gall if you crank on it, and there's no benefit to going past snug. If your neck uses an O-ring, take a look at its condition while you're there, since old rubber is old rubber and it's an easy thing to sort while the cap is off.
Fitment
Compatible with most Honda and Acura engines using a screw-in M33 x P3.5 oil filler neck, from the classic B and D-series through K-series and up to the current K20C. Confirm your cap unscrews rather than assuming based on model, as cam-lock and push-on fillers are not compatible.
Who Should Grab One
This is for anyone building a Honda who wants a piece with genuine history in it, and for anyone already headed down the Spoon path filling in the details. It's the kind of part you add because you like opening your hood, and because a bay full of good parts should look like it. Check your neck, thread it on hand-tight, and enjoy it.
