Injector Tuning Bolt T-4

【GUTS CHROME GSC-018 Injector Tuning Bolt T-4 GUTS CHROME gsc-018】
This is an injector tuning bolt.
Commonly known as the "magic screw".
It's a seemingly mysterious part that, by simply replacing an existing screw, can lead to effects like smoother acceleration and improved fuel efficiency. However, its role is to "remove static electricity."
The spikes on 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 experience tends to be more pronounced in fuel-injected vehicles.
The effectiveness also varies depending on the mounting position for each vehicle model, so please try various methods.
To tighten, use a hex wrench on the screw body itself, not the outer nut.
Screw size M4-P0.7, length approx. 12mm, and one washer are included.
Compatible with: Fuel-injected vehicles from 2006 onwards (excluding electronic throttle models from 2008 onwards)
