50psi or 3.5 Bar Stainls Sensor Kit

The AEM Electronics 50psi or 3.5 Bar Stainless Sensor Kit (MPN 30-2130-50) is a precision manifold absolute pressure (MAP) sensor designed for engine management systems requiring accurate intake manifold pressure monitoring. This sensor kit is essential for tuners, engine builders, and automotive enthusiasts who need reliable boost or vacuum measurement for fuel mapping, ignition timing optimization, and overall engine control. The stainless construction and complete adapter kit make it an out-of-the-box solution for custom engine builds and forced induction applications where pressure feedback is critical to performance.

This sensor operates across a 0–50 psi (0–3.5 bar) range, making it ideal for naturally aspirated and moderately boosted engines. The stainless steel construction resists corrosion and maintains accuracy in harsh engine bay environments, while the 1/8 inch NPT male thread input allows flexible port positioning on intake manifolds or custom enclosures. The complete kit includes all necessary adapters, electrical connectors, and mounting pins, eliminating compatibility guesswork and reducing installation time. AEM's reputation for sensor accuracy ensures consistent voltage output proportional to pressure changes, critical for closed-loop ECU tuning and real-time engine diagnostics.

Professionals and DIY tuners benefit most from this sensor kit when integrating standalone engine control units, upgrading factory ECU mappings, or troubleshooting boost control systems. The 3.5 bar ceiling suits turbocharged four-cylinder engines, supercharged V6/V8 platforms, and nitrous oxide applications operating within moderate boost levels. Installation requires only basic hose routing to the intake manifold and electrical harness connection to the ECU; the included pins and adapters ensure compatibility with AEM engine management systems and most aftermarket programmable controllers. Compact dimensions (3.35 x 2.35 x 4.75 inches) and lightweight design (0.3 lbs) permit easy mounting in tight engine compartments.
