JB4 Universal Water Injection WMI Kit (Steel Braided Hardline Upgrade)Make tremendous amounts of power on pump gas! Water Methanol Alcohol injection commonly referred to as WMI allows you to make tremendous amounts of power on pump gas. The effect is similar to running 100 octane race gas or E85 fuel all the time with the additional cooling benefits allowing for more power than you can make on race gas or E85 alone. The key to a safe and effective WMI setup is tuning integration. All BMS kits integrate to the JB4 tuning

Make tremendous amounts of power on pump gas!

Water/Methanol/Alcohol injection commonly referred to as WMI allows you to make tremendous amounts of power on pump gas. The effect is similar to running 100 octane race gas or E85 fuel all the time with the additional cooling benefits allowing for more power than you can make on race gas or E85 alone.

The key to a safe and effective WMI setup is tuning integration. All BMS kits integrate to the JB4 tuning system allowing for precise mapping based on boost, throttle position, engine speed, intake temperature, advance, gear, and other data elements available to the JB4 through its CANbus system. In addition, a pump flow signal is fed back to the JB4 allowing for a safe and smooth progressive boost mapping. If the tank runs empty or flow drops for any reason the JB4 will safely back down performance to avoid knock. In addition, WMI can be activated or disabled from the driver’s seat, will automatically disengage during traction control or safety map situations, and WMI flow data can be displayed in dash and/or via your JB4 Mobile logging device.

BMS kits include a high quality 220psi Aquatec WMI pump (the industry standard), methanol compatible solenoid with filter, compression fittings reducing the risk of dangerous leaks, and all required wiring and mounting hardware.

The base kit includes a WMI pump, solenoid, FSB for JB4 integration, WMI solenoid, filter, 15' of steel braided hardline upgraded WMI line, pump AN fitting, and required fittings. Using the options when adding to cart you can add on a WMI nozzle (BM10 suggested for most applications), tank, and optional check valve tank tap to keep vapors inside the tank.

Injection Nozzle Options: (Single or Dual Nozzles)

The nozzles are determined by the intended power and how many bungs your charge pipe has. The nozzles are 1/8” NPT and screw into bungs included on most aftermarket charge pipes. Our "super atomizing" nozzles are well known for their great atomization and flow characteristics. The nozzle number represents the approximate gallons per hour of fluid when at full flow. Generally speaking, running two smaller nozzles is preferred to one larger nozzle for an equal flow to improve fluid atomization and distribution. Feel free to email us for nozzle advice if your situation is unique.

Effective
Very good product, not sticky, made my skin feel hydrated, it is very effective and has no scent, the only downside is that while it is good for preventing ingrown hair if used consistently (2x a day on clean skin), it does nothing for pre-existing ingrown hairs.

My new Holy Grail product!
This is INCREDIBLE! Ok, firstly, let me say that I apply it after shaving and razor burn is a distant memory now. It has also taken down the drastic redness and red marks that previous shaving had left my skin w. My skin is smoother and softer now.. including my bikini area. Not to be tmi but, I have a c section scar, it’s nearly impossible to prevent ingrown hairs in that area bc of the scar tissue .. or so I thought! OMG , I’ll never give this stuff up ! It also helps w my back acne and is easy as pie to apply , doesn’t smell weird and absorbs nicely .. bonus points.. it will tame the zits on your bum too .. but wait .. there’s more ! My super pale sensitive skin on my legs has been forever marked w scars from shaving and always has little red marks besides that so I’ve always been insecure about my legs even though they’re long and strong .. dude .. I kid you not, this has been taking the red marks out and no more razor burns.. or bumps plus all of the scars are starting to fade !! This is a HOLY GRAIL PRODUCT! I had literally quit shaving my legs before this and now.. I’m feeling so much better about it & myself and omg thank you for this product! Never ever stop making it !

Decent Product
Ok so I would take this review with a grain of salt because I feel like the results of this product really just depends on how and when you use it. I received my peach slices roller after I already shaved so I’ve been using it as my hair is growing back. And what I can say is … it doesn’t make the ingrowns and all the marks go away, but it definitely makes them appear lighter and they’re not as prominent. However, if I had used this either before or during shaving, I might have gotten a different result. So , as far as it being effective, it’s really the difference between preventing the ingrown and then making them go away. but it’s very smooth and easy to use has a pretty neutral smell.

Staple item!
Seriously so thankful I found this Peach Slices ingrown hair product. I’ve struggled with bumps and irritation for so long, especially after shaving, and this has made such a noticeable difference. My skin feels smoother, less irritated, and the ingrown hairs have improved so much with consistent use. It’s gentle, easy to apply, and doesn’t leave my skin feeling sticky or overly dry. Definitely one of those products I’ll keep repurchasing!

NEW HOLY GRAIL OF SKINCARE
Peach slices is now apart of my regular shaving routine. It got rid of old stubborn ingrowns after every hack in the book. Then it prevents new ones from forming. I’ve been using it for months. It has no smell so fragrance free. It’s also very moisturizing. The consistency is almost like a thinner aloe Vera. If it works my sensitive skin than I’m sure it would work for most skin types
