Water/Meth Injection Questions

[Jaym14]

Not sure if this falls under tech or talk but here goes:

I'm considering installing a water/Meth injection kit on my car but have a few questions.

1. How easy is the install? It appears simple and straight forward
2. Is there much benefit on a NA car? (10-5-1 CR)
3. Will my car require a retune after installation?
4. How often must the kit be refilled and how costly is it?
5. Anyone know of any negatives associated with these kits?

water meth is just like another form of intercooling, if you are not having any problems with detonation right now then you probably wont benefit from it at all

i thought that it was only for supercharged cars or turbo cars. not may people run these setups that i know of. they seemed popular at first but they some how died, i've only seen them on a handfull of cars.
