The spark optimizer, 1Spark, is marketed as the "latest technology in the world- easiest installation." This device is produced and distributed by the company Motorspark. This device is compact, it sits on or below your dashboard and plugs into your cigarette lighter. While driving, the capacitors in the device take power from the car battery whenever there is a fluctuation of excess power and stores it. This power is redistributed when fluctuations in power are less than optimal.
The makers of this product also claim that 1Spark stabilizes the engine combustion of fuel while emitting more power, and efficiently processes the fuel and air mixture so that waste is minimal which should save you money on fuel by utilizing its power more efficiently.
Most vehicle air filters are paper based. The K&N filter is cloth based with an oil seal, and is washable. The fibers in the cloth are crisscrossed and are suspended in place by the oil seal which leaves little room for clogging as there are no small holes unlike with the generic paper filters. Clogging prevents adequate air flow from entering the engine combustion process, which cuts back on the efficiency of fuel usage. K&N filters draw in more air flow, has a 30 percent higher efficiency rating than its paper counterparts, and its filtration system is more productive because it has a larger surface area. This product should be washed every 40,000 miles. The K&N filter has a 10-year warranty and is produced in Australia.
The Hiclone is a stainless steel, maintenance free, cylinder shaped apparatus. The Hiclone fits in the carburetor and creates a swirling effect in the air induction system. This optimizes air flow and assists in the fuel-air mixing to create almost pristine combustion. The makers recommend using two of these devices as one device helps fuel efficiency by 10 to 20 percent and when two are used together, they exceed the 20 percent incline in fuel efficiency. This product comes with a lifetime warranty.
