I continue to see some slick Zs on here with the regular plenum polished. It looks really good when butted up again a shiny intake too. I'm curious if anyone has posted a how-to anywhere on doing this. I dunno where I would start (besides taking the plenum off)

 

we sell polished plenums... there is a core charge unless you send back your stock plenum...

 

Que mucho? And how much does the core charge run?
