I had one of my original fuel injectors fail. I replaced them all with what I thought was a new DENSO set OEM. They were not and I had error codes my truck was running rich. I came across your site doing research and was impressed when you described the 23250-62040 fuel injectors failure mode. Also the correct solution. I bought a set of 6 of your OEM remanufactured and matched fuel injectors ready to install. You also included spare O-rings. It all went well no leaks it idled perfectly. I will come back to MotorWest Performance if I need anymore injectors. I can’t express how satisfied I am. Fedex service parts delivered fast. Outstanding. Thank you!
