if its an 8.1L they should

 

thanks

 

What size injectors do the LQ9 6.0L engines come with?

Jim

 

same as the 5.3s and 4.8s

 

will i need a new harness for the 8.1 inj's??? or is it the same style clip?

 

Nope the harness will be the same as for the clips. i just did a 220/224 .572/.577 114+4 and put the 8.1l injectors in it. i got them off ebay for 95 shipped just last week. they pluged right in and now no more maxing the injectors out.

 

we'll see after this weekend lol, picked mine up from dark halo sunday for 100 bucks.

 

do you need to retune for the new injectors?

 

yes, but you shouldnt need to get bigger injectors with just that cam
