DIY: Adding In-Cabin air filter to the 370Z
Gross. The Fram CF10157 (from Amazon.com) I put in is tons better quality and much sturdier it seems. Fits a wee bit tighter but its great. Took ten minutes to do.
Last pic on the right is the Fram in the packaging with the carbon and baking soda impregnated filter.
