Nozzle throttling

Car owners have a misunderstanding: they think that washing more cars is good for the car, but it is not. Throttle valve is better. Nozzle is a precision product, including multi-point injection, single-point electric injection, direct injection and other types. Usually, it is generally recommended to use something similar to additives to keep the nozzle clean. If it is disassembled and cleaned, it will have a little influence on the subsequent assembly. ?

In short: if it can be dismantled, it will not be dismantled, and if it can be cleaned without damage, it will be cleaned without damage.
