Just a quick post on why as a head porter I like solid aluminum spacers over two inch ones.

Is that your finish in the plenum?
That's a great atomizer

Yes I leave a bur finish as it in known to perform better. It’s not as pretty as a sanded finish but if I had to sand finish everything I ported I would have to quadruple my prices closer to what Wilson charges. My stuff goes on even a little rougher but I can’t send it out the door that crude. Lol
