1. Just tryin to see what you guys are runnin for plugs with E85 and what gap. (part #'s would be great too lol)

2. those that are running the LS4 TB what did you use to connect the TB to the intake? I have a injen currently.

thanks

 

For the LS4 you need a coupler that goes from 3.5" to 3",you can buy it from OTTP or ZZP.

 

Stock heat range plugs gapped from .030 to .035 for E85.
