I had the snow performance methanol injection kit on my mustang. Worked great, and would cool the intake charge so much it you couldn't touch it with your hand. Mine drew right from the wiper fluid reservoir.

 

That's going to be my next mod. It's almost a no-brainer at the cost of 1.5 walnut shell blastings.

 

Good choice. It's maintenance free other than just needing to make sure you get the water/methanol wiper fluid. Also, mine was boost referenced and only activated over a certain PSI. If I recall, my supercharged v8 would go like 5-7 dyno pulls on one reservoir.
