If i remember correctly some guy took in his heavily modded B58 with JB4, water-meth, etc, etc and they blamed all those parts for the failure.... they come to find out the injector failed after further investigation which caused the cylinder to fail. I mean i don't think water-meth would harm the engine if anything it helps it in every way possible... help keep the intake valves clean, keep the IAT low, good octane bump, and of course the M4 GTS has water injection
I just don't understand how a intake can cause the engine to fail and misfire lmao.
