Hey guys i recently bought a motordyne plenum spacer 5/16 iso thermal ... I was just on conceptZ and saw there was a package that provides a copper piece for snowy snowy temperatures? Im in oregon where it mostly rains but can get pretty cold sometimes in the winter do i really need to purchase the copper unit? I tried asking motordyne but its been 3 weeks no reply.... Inputs?!

 

dont need it, just put the one you bought on

 

I'd get on the phone, email them and be a bit of a pest until you get an answer. The copper piece is there for a reason and you want to know what that reason is so unless someone comes up with a definitive answer on this site you'd be better off knowing for sure from Motordyne.

 

Just call tony at motordyne

 

Sonny, Its called the copper isothermal kit, I have a link for you
