I've got all the pieces to swap my TBSS intake and 90mm throttle body. What size injectors are common with this swap? The truck is a 99 but the motor is a lq9 from 2005 (injectors are also from 2005 ss truck) 224/228 114lsa cam , no cats, full length headers.

 

I'm of the opinion that any 6.0 should be running the 8.1 injectors at a minimum

 

Are the 8.1 injectors plug in play? Or do you need a pigtail adaptor for the wiring?

 

Assuming you have the 99 Engine wire harness they will be plug and play.

 

Yes all wiring is completely stock! Thanks for the info!

 

what years will not be plug and play with the 8.1 injectors?
