Using this intake air temperature sensor adapter is easy. First, you have two options for installation. You can use the provided weld bung to attach it to any piping quickly and firmly. Or, if you prefer, you can thread the adapter into a 3/8NPT port and use a sealer to make it secure. Make sure to use the small spacer we provide when using K-Series Temp Sensors. The o-ring on the sensor will prevent any leaks. When it comes to maintenance, keep an eye on the o-ring and replace it if you notice any signs of wear. Also, check the connection to the stock harness regularly to ensure it's secure. This adapter can be used on K-Series Engines and OBD2 B-Series Temp Sensors, and even on newer Drive By Wire cars like the 8th and 9th Gen Civic to replace the MAF with a simple intake air temp sensor.
