There is nothing to say about the ignition system. You can change it if you need to. The car at this price has weak ignition ability and great loss. The manufacturing cost of Sail's original ignition cylinder line is only15m, and it is estimated that 206 is not too much. 1)。 Replace the spark plug with iridium, platinum, iridium platinum and double platinum (the main difference is that the service life is longer when you go to the back). I don't know what type of NGK 206 corresponds to. Ask TX for help. Denso should be IK20. 2)。 The cylinder pipeline must be replaced, otherwise even the best spark plug will collapse due to the current loss of the cylinder pipeline. It is recommended to adopt the latest ESE blue tube cable with grounding wire. I have seen it, and the work is very good, about 380 meters. You can also use Li Shuang ignition tube wire made in China, with the ground wire diameter of 10.8mm (about 380m in blue and 280m in green, which can be bought everywhere) or Lishuang wire with the diameter of 9.8mm (about 220m). Or use a better ER- 1 ignition wire. 3)。 If you are keen on speeding up, you can also replace the capacitor ignition coil (the original factory is inductive and the current is unstable), which is helpful for speeding up. 4)。 You don't have to waste this money, and when you install it, you need 10000 km to wash the oil circuit. You can add five groups of ground wires, and it will take tens of meters to repair anyway.

Exhaust system modification-the exhaust system modification of the corner head is the most important part of the vehicle power modification, which occupies an absolute position in the whole power modification, so we must pay attention to it and spare no expense to modify it. 1)。 The first banana is modified, and the first section of the original exhaust pipe (that has four pipes) of 206 is blank cast iron, and the estimated cost is about 20-40 meters. It is precisely because this thing seriously hinders the exhaust of the 206, so that the excellent engine of the 206 can not achieve perfect power. The interior of this part is rough (the air forms turbulence), and the four S-shaped exhaust branches turn very hard and converge into one pipe, so that the air stumbles through. Therefore, it is necessary to use 304# high temperature resistant stainless steel modified bananas (such as brand Hulox with oxygen sensor holes) to replace the original garbage, and the exhaust pipe must be cut! ! ! ! . If you directly install the so-called modified banana in the original position, it will not work. The modified banana was originally used in racing cars, and now it is widely used in civilian cars. Domestic POLO, BORA 1.8T, 1.8 and Honda Fit are all equipped with modified head bananas. The cost of top banana modification is about 1200- 1400 meters, which can be completed in an ordinary garage. The first banana is the first tonic to improve the strength of 206 in an all-round way, from low, medium and high speed. After changing the first banana, the speed is increased by at least 0.5- 1.0 second.

It is also a good thing to modify the exhaust system-tail drum, which can focus on medium and high speed (such as S-type silent back pressure tail drum) or medium and low speed (such as G-type silent back pressure tail drum). 206 is relatively strong at high speed and relatively weak at low speed, so if the position can fit, use G drum (or S drum, the low speed is relatively weak, but the medium and high speed is G, for example, Hong Kong Weixun series, which has a good reputation in China, has a silent back pressure tail drum, and the speed increase is only in silence. The cost is about 1300- 1600 meters.
