Hi flow LT4 injectors
Just bought a set of LT4 hi flow OEM GM injectors but the part number on the injector is not one I have seen before. Number on the injector body is 12687710. Anyone seen or use these before?

Hey did you search that part number to confirm they sent you the correct injector to reflect they are in fact for LT4?

The only reference I can find to the part number is 2018 Silverado 6.2 litter. Listed as high flow 6.2.

There are 3 different injectors, the ones for the 5.3 engine, the ones for the 6.2 in the Camaro SS and the trucks (I think the SS and the 6.2 trucks use the same ones) and then the LT4 (Z06/ZL1) injectors.
If you didnt get the LT4 injectors and got the high flow ones for the truck 6.2 then you got the wrong injectors.
