    Fits my Ironhead.

    I’m happy with this filter, and it fits in my 1974 Harley Davidson Sportster XLCH 1000. It was my first time buying a sponge filter, and I didn’t realize it needed to be oiled. It would be helpful if this product was sold with a tube of the proper oil.

    Right part for the tight bike.

    The part is exactly what I needed to fit my 68 sportster.
