polished upper spacer?

I tried to find every websites, but couldn't find one that sales polished upper spacer.

 

I think you mean a polished upper plenum. Not a spacer. The spacer isn't
visible once its installed i believe.

 

it's barely visible (thin strip of metal), and is less visible if you put the engine cover on.

 

just take it too a chrome shop and have it chromed or find someone to polish it. i dont know of any company that sells them. well actually i think crawford might. youll have to check it out

any wheel repair shop can handle this for you

 

Sorry to say, the 1/2" spacer is quite visible. Since the engine cover won't
fit and I altered a C/F cover and had it painted, the spacer is very visible!

 

whats the hp gain with a plenum?
and with a 5/16" spacer?
are they really worth it for 300$

 

^^ well everyone has it so i think it is. i dont know the gains tho

 

is it best to go with a plenum and a spacer
what about the MREV2?

 

i know nothing about engine modifications

 

**** im trying to learn im always lost

 

im confused
according to this a theres a plenum spacer and an mrev 2 how do these compare to the upper plenum?

technically, the spacer is supposed to do the same thing as a replacement plenum. People with the kinetix plenum disagree. I don't really have an opinion one way or the other.

Mrev2 is a replacement for the OEM lower intake runners (correct me if I'm wrong). There are mixed opinions on whether mrev2 is worth the extra cost on top of the spacer.

on almost any mod (with the exception of turbos and superchargers) there will be mixed opinions. you just have to decide for yourself.

 

The spacer is the best bang for the buck n/a mod you can do on the VQ.
