Many piezoelectric crystals can be used in water with no issues.
No
Yes they have to be wired correctly. All the injectors do not run at the same time. They only work when needed to supply fuel to a cylinder on the compression stroke.
There was a recall on the fuel injectors on the M30's due to leakage. Just take it to a dealer and they will replace the injectors for free. You'll even get a loaner car while they work on yours.
yes
it is piezoelectric
quartz
Piezoelectricity is the property of a material to generate movement from an electric current, and vice versa. A common piezoelectric material is quartz.
Ur car doesn't work
No, the injectors are rated differently, you would be dumping fuel into the engine. The computer and injectors wouldn't match up.
yes - but they have to be top feed injectors. you can also get low and high impedence injectors, i cant rember which the RX7 uses but it has to be the same impedence. CC can change to suit the desired amount of fuel. cheers.
