Injector Tuning Bolt S-1

[GUTS CHROME GSC-014 Injector Tuning Bolt S-1 GUTS CHROME gsc-014]
This is an injector tuning bolt.
Commonly known as the "magic screw".
It's a seemingly mysterious part that, simply by replacing existing screws, claims to offer benefits such as smoother acceleration and improved fuel economy. Its role is to "remove static electricity."
The spikes at the tip of the screw discharge static electricity, which reportedly allows the air-fuel mixture to flow more smoothly from the injector to the engine, thereby increasing combustion efficiency.
While effective for carbureted vehicles, the effect tends to be more pronounced in fuel-injected vehicles.
Since the effect varies depending on the installation location for each vehicle model, please try various methods.
For tightening, please use a hex wrench to tighten the screw body itself, not the outer nut.
Size M5-P0.8, length 15mm
