When combined with the 7766 NTK wideband module you can read AFR accurately with up to 75psi of back pressure.  With other widebands this is not possible due to their lack of back pressure compensation.  You can use a single 7766 and 7767 module to get per bank information on your engine, or use 4 7766 modules with a single 7767 to get per cylinder AFR readings on your 8 cylinder turbo charged engine.  You can easily pair the 7766 and 7767 with a Power Grid for plug and play operation or use the supplied analog outputs on each module to read AFR and back pressure data on your data logger or EFI system of choice.","brand":"MSD","offers":[{"title":"Default Title","offer_id":50694110675259,"sku":"BCCX_22691","price":147.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/8438\/2523\/files\/22691_0119241.jpg?v=1761961881"},{"product_id":"earls-exhaust-back-pressure-plumbing-kit","title":"Earl's Exhaust Back Pressure Plumbing Kit","description":"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 \u0026amp; flexible Speed-Flex hose assembly.  This kit includes: weld bung, pre-made stainless hardline, Speed-Flex hose assembly, sensor mounting clamp, adapters \u0026amp; hardware.","brand":"Earl's Performance","offers":[{"title":"Default Title","offer_id":50869177188667,"sku":"CFRL_PK0001ERL","price":145.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/8438\/2523\/files\/pk0001erl_011931.jpg?v=1766222666"}],"url":"https:\/\/shop.apexracinglab.com\/collections\/exhaust-backpressure-sensor.oembed","provider":"Apex Racing Lab","version":"1.0","type":"link"}
