    • Massive problems
Size: 2 FIR + 2 IH+ 8 Inj + 1 Press Sens
AD Auto provided substituted injectors that were correct for a 5.7L but not my 6.2L. Caused 25% mpg drop, multiple codes and problems that were masked by the fuel pressure sensor not torqued down causing low mpg and spraying fuel onto the engine and exhaust. Codes pointed to bad O2 sensors. The injectors subsequently damaged the original plus a replacement set of O2 sensors and required another set of expensive high pressure fuel lines to replace the injectors with ones I had to by elsewhere as the AD Auto help form fails to complete, the phone lines are never answered or get a message "User Busy" on my cell phone. Tried Amazons contact procedure. AD Auto stopped communication and told Amazon problem was resolved. ... show more

Review Image by Catherine
Warning!!!!!! 2018 and new use a three pin pressure sensor. Wiring harness and pressure sensor will not work for 2018 or newer. On live data you will see 95k pressure which is impossible. If u do use this for 2018 or new you will have to repin the connector to a three pin and buy a new pressure sensor to a three pin instead of a 4 pin. Other than that they work fine. ... show more
