Rendrox Intake MAP Pressure & Temperature Sensor Kit with Black Spacer for 6.6L L5P Duramax 2017–2024 — Plug-and-Play Heat-Resista

Rendrox Intake Air Pressure and Temperature Sensor with black spacer relocates the MAP sensor to reduce heat and contamination, restoring stable pressure readings for 2017–2024 6.6L L5P Duramax Silverados and Sierras.

If your 6.6L L5P Duramax-equipped Chevrolet Silverado or GMC Sierra has experienced unexplained power fluctuations or intermittent MAP/engine codes, excessive turbo/exhaust heat and oil contamination at the stock manifold sensor is often the culprit. This kit replaces GM part numbers 12681993 and 12707766 with a dedicated pressure and temperature sensor plus a heat-resistant spacer that moves the sensor away from hot exhaust manifolds and contaminated airflow.

How does this kit reduce heat-related sensor errors?

By extending the sensor away from the manifold, the spacer blocks direct radiant heat and keeps the sensor body in cooler intake air. Cooler operating temperatures produce steadier electronic readings and cut down on false fault codes caused by thermal distortion.

• Heat-resistant spacer relocates sensor from manifold to safer position.
• Sensor housing designed to tolerate elevated under-hood temperatures.
• Reduces thermal drift that triggers intermittent power or diagnostic issues.

Will this stop contamination and oil buildup on the MAP sensor?

Yes—moving the MAP sensor away from the exhaust side and adding the spacer reduces exposure to dirty exhaust gases and oil-laden intake flow. That cleaner environment helps the sensor maintain accurate pressure and temperature readings longer between maintenance intervals.

• Spacer blocks particulate and sticky oil from settling on the sensor tip.
• Sensor positioned for cleaner intake airflow and fewer false readings.
• Works with stock intake plumbing; no custom housings required.

Is installation complicated or does it need vehicle tuning?

Installation is plug-and-play and designed for a quick DIY swap—no wiring or ECU programming required. The kit uses OEM-style connectors to ensure an error-free fit, and most installs take only a few minutes with basic hand tools.

• Remove the factory sensor, bolt in the spacer, mount new sensor.
• Uses original connectors—no cutting or splicing wires.
• Typical install time: about three minutes for experienced users.

Which vehicles and part numbers does it replace?

This Rendrox kit is formulated specifically for 2017–2024 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L V8 L5P Duramax. It’s a direct replacement for GM part numbers 12681993 and 12707766.
