Features & Details

  • Gasoline Stage 2 Boost Cooler
  • MAF Triggered
  • More Horsepower and Torque
  • Enhances Octane Rating
  • Reduces Intake Charge Temperature
  • Best Suited for Fuel Injected Applications
  • Fits 1987 to 2010 Mustangs
Water Injection. Water injection, also known as methanol injection, is the method of cooling the combustion chambers of an internal combustion engine by adding a fine spray of a water/methanol mix to the incoming air-fuel mixture. This not only reduces the intake temperature, but also increases the octane rating of the fuel allowing for greater ignition timing for more horsepower and torque.

MAF Triggered. The Stage 2 system uses the 0 to 5 Volt output signal from the Mass Air Flow sensor aka "MAF" (on fuel injected Mustangs) to inject a fixed amount of fluid (49% methanol, 51% water) through the nozzle cooling the engine and boosting octane.

Complete Kit. The Stage 2 Boost Cooler kit includes a UHO (Ultra High Ouput) Pump, 3 Quart Reservoir, Variable Controller, 2 Nozzles all the required hardware needed for installation and comprehensive instructions.

Application. This Snow Performance Stage 2 MAF Boost Cooler Kit is designed for use on both naturally aspirated or force inducted Mustangs equipped with a MAF controlled fuel injected engine from 1987 to 2010.

Technical Note. Fluid is not included.

      Will sct xcal 2 work on this fir tuning?

      • An SCT XCal 2 will work for tuning this Stage 2 kit as long as you have a mustang between 1996 and 2008. We would, however, encourage upgrading to a newer handheld tuner.

      Can you use this kit on a performance n/a 2v? Stage 3 ported pi heads, 39lb injectors, Vic jr intake, comp 274 cams springs etc, 90mm tb, 6061 elbow, jlt cai, 90mm MAF, LTH, o/r x pipe. Also does it require a tune after installation? And what kind of power gains should I expect?

      • The Snow Performance Stage 2 MAF Boost Cooler will work on almost any application from 1987-2010 and aid in reducing intake air temperatures and detonation. A tune will be required after installation, however, the gains will vary from application to application.

      can this be installed on my 2010 v6 mustang with exhaust and also a custom tune?

      • Yes, this would be able to be installed on a 2010 mustang V6 with a custom tune for optimum performance.

      Do we need to go get tuned on the dyno after installation? Quick details about my setup : Kenne bell Supercharger 2.1 boosting 14 PSI, forged pistons, stroked, SCT Programer, headers, full exhaust, and more.. 560 WHP Thank you for the tip :)

      • A dyno tune with all of the mods you have done would be the best route to go with! however a good custom tune from VMP or Unleashed would also work!

      So there is no way to make it work on a 2014 mustang gt?

      • This Snow Performance Stage 2 MAF Boost Cooler will not work with a 2014. For your model year, you would want to look at the Snow Performance Stage 2 MAF Boost Cooler kit for the 11-16 GT, Snow Performance SKU 2132 which we do not currently offer.

      Is there anything els that I need to get other then a tune for this kit to work at its best, do I need to get new fuel injectors or anything like that. I have a 2010 v6 mustang. 1 answer
      How much HP with this gain you on a non boosted 08 GT? I've seen a video of a non boosted charger that gained like 80HP. Seems somewhat reasonable considering the super low intake temps and advanced timing, but wondering if that is really a realistic #. And is it worth getting the stage 3 kit? More power maybe? I have Long tube headers, high flow catted x pipe, Magnaflow catback, ford racing CAI, and a bama tune. 1 answer
      Injection Placement I have ready many different opinions about the topic. Should I run the injection point before or after the IAT sensor? If after, how far after? How close to the TB for a 99 mustang GT? If before, how much before? I am boosted and running 16 PSI from a 70 trim Turbo. My IAT sensor is after my MAF about Mid way between TB and MAF Running A Pro M MAF and 50lbs injectors if that matters. Thank you for your help. I will be running a 51/49 mix from boost juice. 1 answer
      Work with stock v6? WIll this work with a stock v6? it says something about the Mass Air Flow sensor, is that stock or? sorry i just bought this mustang i know more about trucks then cars. Thanks 1 answer

          Firebreathing Stang

          Who would have thought windshield washer fluid could make my SALEEN jump off the ground. Just make sure you get a good tune from someone you trust is not going to blow up your car because the sky is the limit on a supercharged/turbo Stang. 99 SALEEN S/C 14psi 4.10 rear upr tube k-member Stiffler subframe SLP loud mouth long tube headers full exhaust 42psi injectors patriot heads and cams. oh yeah and a Snow Performance Stage 2 MAF Boost Cooler.... I am going to get a larger holding tank and relocate it in the trunk...

          Would be nice if it worked. Snow Performance wants to replace the controller box, which is pretty cool of them. Now I know why they instruct us to test the unit after we hook it up. It's almost as if they expect that controller box to be faulty. My nitrous express kit is a lot more dependable with a micro switch and a relay. Wish this water meth kit had the same set up, because what happens if you're running nitrous, your timing is tuned higher for the meth and it doesn't fire. Guess what happens to your engine? All because of some cheaply made controller box? If I'm getting cheap I'd might as well pay cheap. So Give me my relay and micro switch instead.

          Excellent solution to protect your HP engine

          I purchased this SNOW kit for my supercharged Mustang. It has allowed me to increase boost without excessive fuel enrichment and in fact beyond the boost level that I could achieve with only fuel enrichment. It is as effective as an intercooler without all the piping, intercooler, fittings, etc that is involved with an intercooler setup and can be installed in just a couple of hours. I am running 12 pounds of boost with no detonation and a leaner A/F so I get more power on the dyno. This SNOW water/methanol also has advantages like cleaning the cylinders, valves and pistons of carbon. Being able to run a leaner mixture also reduces the chance of ring wash from excess fuel in the cylinders. Highly recommend this product.

          meth injection

          A very good and cheaper alternative to cooling your IAT's if you have limited space under the hood.

          works good

          I recently installed the water/meth injection to get rid of bad spark knock at higher rpms. I haven't had any spark knock when the water/meth injection system is working. my only complaint, is that the reservoir bottle is too small. I would get a gallon bottle instead

          Great way to get more HP

          I bought this kit in conjunction with my highly modified 95 GTS. I have a vortech T-trim and am currently pushing 17 psi of boost at 7,000 RPM and 653 HP to the tires. This kit not only cuts the intake charge temps down in half but it also adds octane to your fuel (something to the tune of running c16 race fuel). I did not buy the kit from AM, however it is well worth it. I also added the 2.5 gallon fuel tank and solenoid so I could mount it in the trunk, I rarely run low! This kit gives me the piece of mind that I won't be grenading my engine any time soon!
