2 mi from Jim Beam n KY | Behind the air filter is a large black rubber plug, for the lack of a better term, that has about a 1 and 1/2 inch opening. Anyone ever removed it? It seems like it would be restrictive. What is its purpose?
Anyone tried running their bike without it???

Mechanicsville, VA United States | I'm not sure but I think it has to do with intake sound reduction, there are 4 holes in it or 4 tubes....if you get the Lloyds top filter it pretty much does away with any affect from the front filter or the need for it. |

Vineland, NJ United States | when I had my Lloyd's cams, intake and fuel controller installed, the mechanic removed that black rubber snorkel so I don't think it's too important. |

2 mi from Jim Beam n KY | The one in mine just has one hole.
I've tried both of Lloyds top filters and the work great! However, on my 2011, the injectors resonate and the noise is terrible. The noise hits me in the face. So i had to remove them.
Noise out the front shouldn't be bad. Next time i'm energetic I'll dig in and remove it. |

Lexington Park, MD | Question came up before, pretty sure it was on this forum that led into another forum but here are the summerized answers from Lloydz, Rylan and KevinX. If anyone has question about his I am not able to back track the threads I pulled these notes out of and this was in december of 2012. Leave it in as previously stated the 2nd filter resolves it and if I remember in a seperate thread it was mentioned the design of the 2nd filter takes into account the airflow of the bike with the cone installed. Here are the cliff notes:
Killing time and updating some threads.. lol.... I think you got this answered on another forum that it should stay in unless you have upgraded to the TWIN air intake at which time it can be removed (this was performed by KevinX on another riders bike during upgrade to twin intake and cams) Thank you Gunslinger for the Q's which I have now included the updated info in the post!
Also, I am not sure where I posted the Ness vs Lloydz 2nd filter but according to Lloyd his design will allow for up to 60% more air flow over the Ness square 2nd filter. That was taken from a conversation a few weeks ago btwn VicBuilder and Lloyd after there had been discussion about the filters and their designs.
As for upgrading the front filter, after what I have read I do plan on installing the Vic performance K&N STYLE filter when my stock'er is due for replacement. I have plenty of filter cleaner and K&N oil thats for sure... Darn sales... lol...

2 mi from Jim Beam n KY | I'm running the Ma Vic HiPo air filter and a VFC III. I miss the extra kick in the butt you get from Lloyds top filter.
That rubber stopper has to create tubulance because of the relatively sharp edges. I'm considering modifying it to flow more air or just remove it entirely. Modifying it seems like a decent compromise. |

I presume it comes out the front? What are folks using to grab it and pull it out with?

2 mi from Jim Beam n KY | Its too big to remove from the front. You have to remove it via the top plate. |

| I'm thinking leaving it in helps forcing the air flow backweard's. With air flowing into a square opening it has to have a direction to go.

Shit, and I just got done installing my Lloydz top filter with the flexible gasket sealer.... Grrrrr....

Almost like a venturi effect? Maybe.

Beer Collins, Colorado (there is no fort) | It has to come out the front if you want to pull it-no way your getting it out the top-I believe these torque tubes should be left in place as they direct & compress air flow.

2 mi from Jim Beam n KY | The 08 is WAY DIFFERENT than the '11. The '11 only has ONE hole(tube) that would appear to be about the size of ONE of the tubes from the '08! |

Yup. My 11 doesn't look like the one pictured either.... only one hole. I'm almost thinking of removing that plug and putting my top plate back on. I can't see how that wouldn't give the bike plenty of air. |

| the only way your going to pull it is out the front. How would you get it pass the stearing stem. or even reach it

Beer Collins, Colorado (there is no fort) | I looked up a 2011 and it looks like the single air tube (13) was added in addition to the quad tubes up front. this piece would have to come out the top opening I suppose. I'm guessing it's an EPA thing that was added to quite the intake a bit more?

I wager that the tubes are designed to smooth the air flow, before the throttle bodies ingest it. less turbulent air. Air boxes are designed today to work with the power pulse of the engine. It's engineering voodoo |

I would agree. It's the same reason we used to put velocity stacks on our old carbureted sport bikes-- to smooth the air flow and increase the intake air velocity for better performance. I suspect the guys who are pulling those tubes out are shooting themselves in the foot.

Georgia, west of Atlanta | Just replaced my old style Lloydz top filter ( two foam holes in metal plate ) with the new blue K&N style. There's no way any air is coming in the front filter now. Just leave the stock filter in place up front if you use this option............. |

Wouldn't the increased performance we all realize by adding the top filter (Ness or Lloydz) kinda negate that concept? |

Yep. But.. she is ingesting more air with the top filter... as opposed to just having the OEM forward filter and no tubes installed. That is the benefit. |

Georgia, west of Atlanta | I did not notice any increase or decrease of intake noise from the early lloydz foam filter to the blue K&N style filter. It ( the filter ) may flow more air, but but airflow is really the combination of the ports, cams and throttle body size, but it's doing it from a much larger filter area. New filter 25.5 sq inches of filter media vs the old 9.8 sq inches of filter area, plus the new media is better than the foam.............. |
