MCS, Blue Lightning air filter element for Harley Davidson

At an economical but high quality price, it offers a higher flow, longer service intervals, better fire resistance and will last much more than comparable paper or foam filters. 
The filter elements are built with 4 layers of previously greased cotton filter filtering. 
This will maximize air flow but will still provide adequate filtering capacity, matching the best market performance filters. 
Very durable thanks to the use of coated wire mesh. 
Washable and ready to provide years of use without problems. 
Note: All air purifiers mentioned here are for HDI (HDI = International H-D models or simply "out of the United States models.") Unless otherwise indicated.

Compatible with:> 86-89 Big Twin with round air purifier
