they have dates on the injector body, my aunt workes for bosch she was telling my how to read the production dates on them but i forgot. when the bodies started failing bosch did find out the cause and made the bodies a little stronger, but they still fail... just not as often.

going on set #4 on my truck, remans suck -

are there any other less expensive upgraded injectors for the LB7? $1,100 for a set of injectors that bump 50hp at the wheels seems high.......or am I off-base? -

ill have to ask my aunt again, she knows it all to well. i need some numbers to tell her though -

I saw the numbers but had no clue what they meant I'll see if I can sneak into parts and check out a few. -

No go. Parts manager said if I open the box I bought it . Which at the rate my truck is going I may as well. -
