    This is a great intake system. Bought for performance increase, overall look, and clearance for my legs for the forward controls. Only gripe I have with the system is the filter must be a harley only replacement because I can't find it anywhere on k

    I think the size was overwhelming at first, BUT the, performance is superb. Very noticeable improvement coupled with the stage II upgrade. Because of the oval shape and bend it is not in the way with my legs with the floorboards or Highway pegs.

    I bought this thinking it would make my motorcycle faster and look good. But after riding for 40 miles and 3k rpm it starts leaking oil everywhere. I’ve torqued the bolts several times and it still leaks. It has leaked over 5 times I will definitely be buying a new one

    • My HD dealer did not follow the installation steps. Had one of the main bolts work loose enough to become visible, one secondary bolt fell out, I disassembled, found no evidence of blue thread sealant, corrected their error and now no more oily issues.

    I have a 24 Breakout with factory heavy breather. Will I get any gains transitioning to this heavy breather?

    When will we see an option for the filter only? I don't need the kit, just the filter for a spare.
    Ram Man - Ontario
    • Answer:
      Hi Ram Man, Our Screamin' Eagle Heavy Breather Extreme Air Cleaners are washable, and don't require a replacement. Unfortunately, if you're in search of a secondary filter, the only option through the online store is to buy the kit. Alternatively, you may be able to acquire just the filter through the dealer. Thank you read more.

    Hello why does it say it will not fit a 21 road king special? The 117 has a similar version and that fits.
