Have any of you guys used them in your LS1 and if so how did they work???

 

if they are anything more than $2 each...they are a waste of money.

there isn't anything to be gained from fancy plugs other than a smaller bank account.

stick with the time tested NGK tr55s for $2 each

and dont bother with platnum either...for the added cost you can change the standard plugs several times over.

 

What, you didn't like the answers you got from your other post about splitfires? THEY'RE A GIMICK. If you are dead set on them then you might as well get you a turbonator, fuel catalyzer, and a tornado air.

 

 

Nope I changed the plugs but I used AC delco Ired. It feels a lot beter plus the back fiering problem went away.
