Only three things needed. You need 1xair compressor filter, 1x A-128 compression fitting and 1x A-122 compression fitting. Thats it, no ugly hose clamps or heater hose. Just cut the ends off the stock hard plastic piece. Cut off the bend area to where all you have is the straght pieces with the raised sections that fit into the stock rubber boots(pull the piece off you will see what i'm talking about). You will have to sand the ends of the side that u cut so that the compression sleeve can slide over. I also put a dab of silicon on the compression sleeve, because it kept sliding on me when i went to compress it down. Once you have your pieces put together all you have to do is screw them onto the filter and you are done. I also cut down the foam cover piece that previously covered the plastic hose so that it would fit around the exposed areas. Here's the pics.
*edit*If you read down the page there are some good time saving alternatives to using the compression sleeves.
