Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Snow Performance ProLine Meth Injection Solenoid Valve Upgrade

Lock out unwanted fluid run-on and keep your tune safe with the Snow Performance ProLine inline solenoid. This high-flow anti-syphon valve only opens when your controller commands spray, then seals tight to prevent gravity feed, drain-back and vacuum draw the rest of the time. Perfect when the tank is in the boot or the nozzle sits lower than the reservoir, this is the safety shut-off serious boosted builds rely on for clean, consistent charge cooling.

Key reasons to choose it

  • Stops unwanted flow when the system is off to protect engines on turbocharged and supercharged applications.
  • Class-leading flow for steady delivery and crisp atomisation under boost.
  • Female 1/8 NPT ports with supplied Dash 4 AN adapters for ProLine stainless braided hose.
  • 100 percent stainless construction for corrosion resistance and full methanol compatibility.
  • Universal inline valve that integrates with Snow Performance kits and advanced meth controllers.

We run this upgrade on our own builds at MJ Modifications and customer feedback has been excellent. Strong sealing, reliable operation and cleaner plumbing for water-meth setups of all levels.

What you get

  • 1 x Stainless solenoid valve with 1/8 NPT inlet and outlet.
  • 1 x Mounting bracket with 2 x screws.
  • 2 x Dash 4 AN fittings for ProLine steel braided lines, fully methanol safe.

Fitment guidance

Universal use across most charge-cooling and auxiliary injection systems. Designed to pair with Snow Performance ProLine braided hose. Running 1/4 inch nylon line with push-to-connect fittings? Choose the Rapid-Fittings version or contact us for advice.

Note: ProLine braided hose can be retrofitted to existing Boost Cooler systems that use 1/4 inch Nylon or FEP line. Swap the push-fit connectors to Dash 4 AN to convert.

Professional fitting recommended. MJ Modifications, based in Warwickshire, can install and set up your system. Request a quote via info@mjmodifications.co.uk.
