Does BMW 5 Series brush a first-class injury car?
It depends on the quality and adaptability of the project you choose. Generally, the first brush will be done with the B M3 program, which won't hurt the car. According to BMW's official explanation, the first-order program of B48 engine brushing BM3 does not need to change the hardware, and the second-order program needs to replace the exhaust head, so the first-order brushing with the original program has little effect on the engine. However, it should be noted that, in fact, no matter any car brushing procedure, there will be certain risks, and not all models can guarantee that the engine life will not be damaged after the first car brushing.
How much is the first-class brush of BMW 5 Series?
Different procedures, different prices. If it is BMW's official BM3 plan, the first phase will cost about 4,200 yuan. Although the BM3 program is expensive, the adaptability and quality of the program made by the manufacturer will definitely be more guaranteed. Secondly, if the budget is low, you can choose the Eisen plan. The price of series 3 first-order Essen scheme is around 1800-2500 yuan, and the power improvement rate is similar to that of BM3 scheme, but the stability is not as good as that of BM3 scheme. Other small factory schemes will not be introduced one by one. Anyway, it is best to go to a big brand modification shop to brush the program, so as to avoid unnecessary trouble in the future.
