Just bought a new 15' fourty eight and was wondering what filter I should go with running the V&h shorts exhaust... Arlen? Roland? Joker? V&h? Etc.... Performance and looks is what I want ... Thx for the help guys

 

I went with Figure machine

 

DK 578 Outlaw Highflow.

 

I've just got the stock air intake on it now. (2015 Iron 883).

I am still stocking my garage with tools/equipment so I can do all the labor myself on most projects and bypass the 400% markup the dealers put on everything.

I'm going to collected up three things to do the project all at the same time.

Vance & Hines - short shot pipes (black)
Vance & Hines - V02 air intake
The black cover for the air intake
Fuel Pak

All items from the Vance & Hines website.

 

DK Custom's Outlaw 587 Chrome Bobber Stage 1 AC


Check out this thread for pics of a lot of different air cleaners.

im installing a figure machine

 

K&N 3" from Hammer Performance

 

There are only a few companies making true performance intakes anymore.

DK Custom
NRHS
Hammer

I don't know of any others.

Pushing blow-by back into the air cleaner is counter productive to performance. What comes out of the breathers is primarily exhaust and oil.

It is also hot. Engines perform better with cool dry air and gas...not hot oily air and gas.

Additionally the exhaust gas has a lower oxygen content, displacing oxygen on each combustion stroke. Another performance robber.

Oil will build up carbon deposits on the pistons, leading to pinging/tuning problems down the road.

It's just a bad idea...the only upside is you make the EPA happy.

You can see the dozens of different looks of the DK Custom Outlaw A/C's, we have the 587, 425 and 636v. Also at those links are dyno charts showing the bump in torque and HP, by just NOT venting the hot oily air into the intake.

Here is an example of each one...

636v

 

K&N.....just cleaned and oiled it this week

 

I went with Rough Crafts. It's not a K&N filter but I will be replacing with one after a while. It came with everything to mount. Has internal breather system.
