Snow Performance Diesel Water Methanol Injection Kit VC50 52mm BAR OLED, 300 PSI Pump – Universal Turbo Diesel WMI for TDI TDCi dCi CDI HDi JTD – EGT/Intake Temp Reduction, Boost Cooler Stage 2E Power-MAX Europe Spec – SP10251

Diesel Water-Meth Injection System for Turbo Applications - Europe Spec - Part No. SP10251

Unlock cooler charge temps, safer EGTs and repeatable power on your boosted diesel with this Europe spec diesel water methanol system. Featuring a 52 mm OLED display controller in BAR, an ultra high output 300 psi pump and precision atomising Hyper-Sonic nozzles, this universal kit delivers progressive, boost-referenced injection for reliable gains on tuned TDI, TDCi, dCi, CDI, HDi and JTD engines, plus trucks, vans and marine diesels.

If you are searching for a diesel methanol injection kit, water injection for turbo diesel, WMI for TDI, diesel charge cooling upgrade, diesel EGT reduction kit, methanol injection for towing, diesel performance cooling or universal water-meth for remapped diesels, this package is the one our customers keep choosing. We run this hardware on our own builds and feedback has been consistently strong for intake temperature drop, smoother delivery and clean, dependable performance.

Why enthusiasts choose this diesel water-meth system

• Progressive, boost-referenced delivery through a 52 mm OLED controller in BAR for smooth and accurate fuel mix control
• Up to 60°C intake temperature reduction for denser charge air and repeatable power on road, track and when towing
• Helps bring down exhaust gas temperatures to protect hard-worked turbo diesels under sustained load
• No intake restriction, no intercooler pressure drop, outstanding charge cooling under boost
• Assists with knock suppression on suitable applications and reduces NOx by cooling the charge
• Steam-cleans valves and piston crowns to combat carbon build-up
• Headroom for more boost and timing where appropriate with proper calibration
• Integrated system monitoring for boost, tank level and injection quantity

Real-world gains

On turbocharged engines, users typically see up to 10 to 25 percent more power thanks to the dramatic drop in charge temps and improved air density. Expect crisper throttle response, stronger mid-range and safer sustained output when driving hard, towing or hauling.

Nozzle and tank guidance

We will help you choose the correct nozzle size to match your boost and power level. V engine layouts with dual intakes typically need one nozzle per bank. Supplied with a 3 litre tank as standard, with optional 9.5 litre and 26.5 litre upgrades available for extended range.

Compatibility

• Universal for turbo diesel engines up to 3.5 bar boost
• Popular across TDI, TDCi, dCi, CDI, HDi, JTD platforms, pickups, 4x4s, vans and marine applications
• Works brilliantly with remapped diesels and larger turbo conversions

Setup made simple

Set the boost where injection begins, then set your maximum boost. The controller progressively varies delivery between those points for seamless performance. Add Dual Stage Technology to define a second nozzle map for high-load or high-boost operation.
