Flyin Miata DOTD: Spearco Water Injection
 

Best get on it!

Spearco water injection kit

Water injection makes your car cooler. No, seriously! You can either use it to quell knock or to drop intake temperatures. Nicely suited for use with superchargers in particular when you're worried about throttled volume. This isn't the most sophisticated kit around but it does the job. Nicely fabricated aluminum tank too.

Fits 1990-2005
Price: $60

hmmm, simple enough. Uses a pressure switch to activate a the pump in boost. That's a steal for a super simple entry level WI kit. Still, with the size of the bottle and lack of warning lights, it's probably something I'd want to use in conjunction with an IC or as a IC sprayer.

I know this deal is gone, but a Shurflo pump of at least 60 psi is going to cost the average person $60 for just the pump.

Yeah that was a good deal. Last week they offered their additional injector controller for $100. I should have bought one.
