Skunk2 Fuel Injection Manifold Pressure Sensor

Skunk2 Manifold Absolute Pressure (MAP) Sensors for Forced Induction

When your engine build pushes beyond the limits of factory components, sensor accuracy becomes just as critical as the hardware making the power. Skunk2 Racing — a brand synonymous with Honda and Acura performance since 1994 — extends its engineering philosophy into the world of fuel injection sensing with a focused lineup of Fuel Injection Manifold Pressure Sensors designed specifically for high-boost forced induction applications.

Why the Factory MAP Sensor Isn't Enough

The Manifold Absolute Pressure (MAP) sensor is a cornerstone of any fuel-injected engine's electronic control system. It relays real-time manifold pressure data to the ECU, which uses that input to calculate accurate fuel delivery and ignition timing. The problem for performance builders is straightforward: the OEM Honda MAP sensor is calibrated to handle only around 10–11 psi of boost. Push beyond that threshold with a turbocharger or supercharger, and the factory sensor saturates — leaving the ECU working with incomplete data, which translates directly into poor tuning, unsafe air/fuel ratios, and lost power.

Skunk2's Solution: Multi-Bar MAP Sensors Built for Boost

Skunk2 addresses this limitation head-on with upgraded MAP sensors engineered for elevated boost levels. Their sensors feature sensor-on-chip technology that accurately and precisely measures manifold pressure well beyond what the OEM unit can handle — up to 29.0 psi of boost in their higher-bar configurations. Available in 3-Bar and 4-Bar variants to suit different power levels and platforms, Skunk2 MAP sensors cover popular Honda B-series, D-series, H-series, F-series, and K-series engines, as well as the Subaru FA20 found in the BRZ and FR-S/FT86.

Critically, these sensors are plug-in compatible with the OEM MAP sensor connector, making installation straightforward — no wiring adapters or custom harnesses required. This direct-fit design is a hallmark of how Skunk2 approaches the performance aftermarket: race-derived function without unnecessary complexity for the builder.

Engineering Backed by Real-World Racing

Skunk2's credibility in the sensor space flows directly from their broader engineering ethos. All Skunk2 products are carefully planned and designed in-house using computer simulation and modeling techniques, then validated in controlled laboratory environments with state-of-the-art equipment. Each component is subsequently subjected to dyno, street, and race track testing to confirm performance under the most extreme conditions — the same conditions their MAP sensors are designed to operate in reliably.

For builders running big boost on Honda or Subaru platforms, Skunk2's MAP sensors offer a precise, proven, and hassle-free upgrade that ensures your ECU has the accurate pressure data it needs to make every tune count.
