STI Oil Filler Cap

An oil filler cap that combines a resin cover with an aluminum base cap that has been die-cast and cut.
The shape of the cap is carefully designed so that it can be easily rotated even when wearing mechanic gloves.
In addition, a service hole that can be removed with the wheel wrench of the in-vehicle tool is provided under the resin cover in case it is difficult to remove, improving the detachability.
Coloring that combines silver aluminum, black with grained cap, and cherry red with the STI logo adds functional beauty to the engine room.
