This plumbing kit includes the components needed to install an exhaust back pressure sensor (the sensor is available separately – part number 554-102). This type of sensor is often used with data acquisition, or EFI systems to monitor the exhaust back pressure just prior to the turbo. The exhaust heat and engine vibration are tough on the sensor, so it is mounted remotely and isolated by the stainless hardline & flexible Speed-Flex hose assembly. This kit includes: weld bung, pre-made stainless hardline, Speed-Flex hose assembly, sensor mounting clamp, adapters & hardware.

About Earl's Performance
Earl's Performance Products was founded by Earl Fouts in 1955 in Lawndale, California. The mission was to supply high-quality military aircraft surplus plumbing components directly to the racing industry from a small retail outlet. As the military surplus market dried up, Earl recognized the need for continuity of supply for the racing market and pioneered the Earl's range of hoses and fittings that are still used today. In doing so he created the racing aftermarket plumbing industry.
