Has anyone replaced the coil springs with the Supersparkz? Just curious if it made a difference and where to find them

 

The guy you got the PP TB is the guy that makes them. IMHO they won't hurt anything.... but do not expect an improvement. As long as your OEM coil on plug packs operate without issue, you are getting a full and efficient burn.


Kinda like fancy spark plug improvements years back, like Splitfire, U Grove, multi electrode...... while that all sounds interesting, absolutely nothing shows up on a Dyno. My bro-in-law works at GM in the Tech Center lab, they tested all those plugs and if they made any power, they could not measure it at all.
