Special 107 / 114 CI Racing filter element. filtering efficiency is extremely high at 98-99% filtering efficiency (ISO 5011); with 4 layers of DNA® cotton material. Designed for racing use but installs as a drop-in replacement filter and fits the stock filter housing. Offers a staggering 35.23% more flow than the stock H-D filter element and about 30% more flow than the standard replacement DNA filter element (MCS 934217). This Racing filter reaches its excellent flow figures purely by design; not by removing filtering layers as some manufacturers tend to do. I therefore offers the same excellent 98-99% filtering efficiency as the Standard DNA filter element. OEM replacement reference 29400212
