We provided a CT4-V Blackwing airbox sample and worked in conjunction with Green Filter to design these air filters for maximum performance. Green filters are constructed with four layers of tightly woven cotton gauze, rather than open cell foam. This is thinner, stronger and easier to clean than other materials. If you look closely at the competitor’s aftermarket filter design, you’ll see they avoided adding the angle, which reduced the overall surface area. By increasing surface area, this design actually increases air flow.
Green Filter uses stainless or annealed steel mesh, which is stronger and allows more intake pressure, compared to the competition which uses aluminum instead. Green’s filter oil is 100% synthetic, which is safe for all engine sensors. The oil provides a positive magnetic charge, which attracts negatively charged dust, trapping particles as small as 5 microns. Easy to install, clean and maintain. Sold in pairs.
Green high performance air filters come pre-oiled. As a general rule, they should be cleaned at every 30,000 miles. However, this interval can be greatly influenced by your environment and driving conditions.

There are 12 screws that will need to be removed to install these filters. They go around the perimeter of the airbox, and there is one in the very middle of the airbox. This includes both MAF screws.
