11. Vanity Shift Knobs
You can decorate your shift knob with just about anything, including a smashed PBR can or a piece of “Jurassic Park” mosquito amber, ranging in price from the traditional $20 eight-ball to a $85″ hand grenade. But in reality, unless you’re dealing with a carefully preserved old automobile, vanity shift knobs rarely offer character. The majority of these knobs are outdated and childish, which might prevent appropriate shifting.
12. Intake Vortex Devices
Intake vortex devices rely on drivers’ ignorance of how modern engines function, like so many other fuel-efficiency items that make bogus claims.
The claim that automobiles can benefit from accessories like intake vortex devices, which work to change how much air enters the combustion chamber, ignores the reality that modern vehicles already depend on sophisticated computers to continually modify airflow to meet fuel intake and vice versa.
13. Hydrogen Generators
The premise behind this kind of fuel-efficiency gimmickry is that hydrogen is a more potent fuel than gasoline. Even if there is some validity to such notion, it is just not applicable to automobiles.
According to hydrogen generators, hydrogen is produced by isolating oxygen from the water supply of your automobile and diverting it to your fuel supply. The type of electrolysis equipment utilized for this has the drawback of only producing minute quantities of hydrogen. They use your alternator, which they put under a great deal of stress, to drain power from your car’s electrical system in order to do this.
14. Fuel Vapor Injectors
The idea of fuel vapor injectors doesn’t hold water with individuals who understand how engines operate, much like the other ‘fuel-enhancing’ gadgets. The most you can expect for with this fuel-vaporizing device is performance that is similar to what you would have gotten from letting your factory-installed fuel-injection system handle the heavy lifting.
The worst case scenario for a fuel vapor injector is that it will cause your engine to run “rich,” with too much fuel and insufficient air. When it comes to so-called fuel enhancers, consider this: If manufacturers could install these components at the factory and still achieve significant fuel savings, why wouldn’t they do so?
15. Racing Engine Simulators
Any arcade in America will let you to indulge your desire of operating a race vehicle for a few quarters. That’s a lot better result than spending $40 on a sound simulator, many of which are poorly built and end up serving as nothing more than a diversion.
Adding sound to ultra-quiet electric engines can improve safety. However, it is unnecessary to drive a Camry that has been modified with a device that emits the recorded sound of a Shelby engine. Additionally, it consumes a lot of energy and, like bogus performance badges, is really depressing.
