Change exhaust - reduces exhaust back-pressure, low torque will drop, engine exhaust valves will be easy to burn because of the ultra-high temperature.
2. Mounted mushroom head - to reduce gas into inertia The low torsional will decline, increased fuel consumption, low speed weakness.
On balancing rod, tie rod - local vibration more severe, permanent damage to bodywork.
The converted audio subwoofer - exaggerated the volume of the subwoofer owners will unknowingly damage hearing, high-power sound often makes the circuit is overloaded with work, easy to burn the switch and cause a fire.
5 plus gasoline, lubricating oil additives - the gasoline oil line cleaners will dissolve the impurities in the fuel filter after direct clogging fuel injectors, oil additives only applies to moderate burning oil and old cars, any new car will lead added fever and severe wear.
Change tires - started inability to accelerate the slow, steering wheel-Agency accelerated wear.
7. Installation of multi-point coarse ground - resulting in the high-pressure line is not normal, shortening the life of Fireworks plug, sometimes confusing computer will increase fuel consumption.
Car perfume - almost all chemical flavor, toxic interior plastic embrittlement corrosion for a long time will somehow burst, causing great harm to their health. Stuck in the air conditioning vent perfume bottles often cut off from the outlet wind guide piece.
9 car door soundproof - sound only to complete the vehicle production process, and can not tamper with. The silencer principle, not posted there, this is a problem of acoustic equalization offset. Often you every door would listen to the engine sound is more obvious every engine sound will lead to the car the abnormal sound sounds more messy.
10. Sealed plastic chassis - 99% of the original car has a tract processes, and are thick enough. And then spray mess up the only closure under the chassis should not seal consequences only discovered later maintenance.
11. Changed the headlamps - increase the lamp power directly over the original design of the temperature value, not a few days will melt burning lamp bowls reflective layer, the lights are dim, and the reason is that the lamp bowl thoroughly reimbursement. Transparent cover headlamps now are synthetic materials, over temperature will turn yellow, and slowly a section of the small crack, the lamp current will slowly burned headlight switch line, causing a fire.
12. Sealing glaze - 100% scam, it is just hard wax like something, you need to use high temperature dissolved before light, this process will cause the paint to overheat internal injuries.
13 the car leather waxing - leather class fine pores, penetrated to anything very difficult to sustain clean out suture is one more encounter wax should not even think about wash out.
14 glass of water - I do not know specifically what substances harden wiper rubber, also coated with a layer of film on the glass will leave a piece of uneven after failure.
Rear window stickers Solar Films - above the rear window are printed thin-film circuit, once the film will never be torn, printed circuit when the Solar Films failure needs to be replaced, a tear will tear the piece of the rear window almost scrapped.
The 16 tires filled with nitrogen gas, plus self-complementary glue - nitrogen content of the air is 70%, nitrogen is not an inert gas, in other words: Is Pianqian to. Tire self-complementary glue limited effect, side effects damage the tire balance, corrosion wheels and tires.
17 surrounded by large - supercar ground clearance only in the super-highway to travel, mostly surrounded by large non-original soil falling nondescript do not say, first broke several expensive and still can not find the accessories parts, before loading up after every day should be careful when will fall to the encounter collision, such non-original pieces guard the security of your life will produce great harm.
