Air Filter Compatible With FC90 FS87 HL90 HT101 KM100 Replaces 4180 120 1800

This is a high-quality aftermarket replacement part, these parts are often made by the same company that make the branded parts, these Stens parts offer a really good alternative to OEM parts and are brilliant value, yes you may find cheaper but I doubt you will get the same quality of part unless you buy genuine replacement parts.
