St 2 Water/Methanol Injection Kit Gm Maf Referenced
Product Information
This kit uses the unique GM MAF frequency Hz output signal. Perfect for naturally aspirated applications and forced induction applications that build boost quickly at lower rpms. This allows for accurate delivery of water-methanol and allows the most cooling and performance improvement over the widest range. More power and driveability is the result.Kit includes:
• SHO (Special High Output) Pump
• 3 Quart Reservoir
• Digital Variable Controller
• 2 Nozzles To Cover a Wide Range of Horsepower
• All Required Hardware Needed For Installation
• Comprehensive Instructions
• SHO (Special High Output) Pump
