LS MAF Sensors

The LS engine family utilized 5 Mass Air Flow (MAF) sensor designs, most notably the early 3-pin and 5-pin "tube style" sensors found on 1998–2002 Camaros and 1999–2007 Trucks. This truck sensor featured a tongue style 5 pin connector, where the center projects past the outside of the connector housing.

Later, a unique hybrid style sensor was introduced on late 2007 (new body) through early 2009 trucks, featuring a removable round cartridge held by an internal clip rather than hold-down bolts like modern card sensors use. This hybrid style sensor was the first to adopt the modern 5 pin connector seen on newer Truck Card and LS3 style sensors.

Even though these three modern sensors share the same plug, they will not work interchangeably due to completely different wiring pinouts. They require one of our MAF sensor wire adapters to function. We offer a full line of adapter harnesses available for any sensor upgrade combination.

For high-performance applications, the modern "card style" LS3/LS7 sensor is the industry standard. Switching to the LS3 sensor allows you to build a custom air intake unrestricted by fixed tubing diameters. We stock weld bungs for all LS MAF sensors, as well as MAF plugs if you are moving your sensor to another location in the intake system.

If you are adding a supercharger, we recommend relocating the Intake Air Temp (IAT) sensor into the supercharger. This allows you to accurately measure post-intercooler temperatures while still maintaining the MAF signal. Any of the LS MAF sensors allow for the IAT signal to be relocated.
