The Skunk2 4 BAR MAP Sensor is a high-precision, direct-replacement sensor designed specifically for forced induction setups in Honda K-Series engines (excluding K24Z) and FA20-equipped vehicles such as the Subaru BRZ, Scion FR-S, and Toyota 86. Engineered with advanced sensor-on-chip technology, this MAP sensor accurately measures up to 43.5 psi of boost, making it ideal for turbocharged and supercharged applications.

This sensor is built to withstand the high heat and harsh conditions of high-boost environments, offering excellent durability and reliability. It installs directly in place of the OEM sensor, eliminating the need for modifications. A programmable ECU is required for proper calibration when upgrading from the OEM 1 BAR MAP sensor.

Key Features:

• Supports up to 43.5 psi of boost (4 BAR)

• Designed for forced induction (turbo/supercharged) applications

• High-precision sensor-on-chip technology

• Water and heat resistant construction

• Direct OEM replacement – no adapter required

• Ideal for custom-tuned ECU setups

• Reliable performance under extreme engine bay conditions

Important Reference:

• 1 BAR – Naturally aspirated (atmospheric pressure only)

• 2 BAR – Supports up to ~14.5 psi boost

• 3 BAR – Supports up to ~29.0 psi boost

• 4 BAR – Supports up to ~43.5 psi boost (this sensor)

A programmable ECU is required when upgrading MAP sensors to avoid incorrect AFR readings and engine performance issues.
