Here is a good one from another thread by JackandJanet.
The snorkel with the small opening is separated and removed from the large opening of the flex section.

well when the motor breaths better it runs better just like people if thy smoke its like the stock intake and some one who didn't smoke is like the modded intake plus cold air is dincer and thus creates more volume and better combustion due to that and if my math is on its like 7 more cfm in to the motor stock is 1.75" and modded intake is 3" now i got a k&n drop in as well so when i dynoed mine it was and will be higher than a stock paper filter plus if you have duels exhaust this help expel the air easier thus breath better

This mod just removes the restriction at the snorkel end. When Bill Cohron tested it on the dyno he saw a gain of 7-8 RWHP in the upper RPMs(above 2000) over stock.

Got all of my stuff today. I recommend going to lowe's because they had no clue what the rubber piece was and they didnt even have it. I went to lowe's and gave them the part number from page one and they gave me the missing part. I put everything together and even got rid of the ULGLY front and rear silencer boxes and plugged the holes. I will post pics up later!!!
