HOHOHOHoooooooooooo aw man is that sweet or what? Geez, I was going to get this https://www.4multimaster.com/default.jsp to assist me in laying the Queens walnut floor but I may have to just remove all the trim because what the heck it should be replaced too.

Yes, very very sweet !! Been waiting for such a piece. I was seriously thinking about taking the stock unit and port and polishing it to get a better flow through it. This unit will do the trick very nicely.

Now with an opening to full size like this one ....

Doing a small amount of polishing and smoothing the edges, it will make for some serious flow

Polish the internal to the fullest extent, soot build up will drop to nothing since it will have no pores to stick to. Do the same to the manifold and soot build up in the intake would be null !

Been thinking about that same tool for a long time, so far, been able to do all my work without

Cheers,
Roberto

There are a few other intake horns out on the market aswell that flow even better !

Yes there is (just slightly better), all have a design flaw which makes then not flow to max efficiencies even with the smog ports fully operational. None of which are smog legal except for one and that company makes it a pain in the arse to purchase one in a oem looking form. Nothing but bright screaming colors ..... Not my style.

Think its time to fire up the machine shop and make my own
