CNRAQR 12mm Fuel Cell Breather Filter with 8AN Fitting – Performance Air Intake Kit

Upgrade your engine’s breathing with the CNRAQR 12mm Fuel Cell Breather Filter. This compact kit combines a 0.85 micron 20 mesh grid with a chrome coated aluminum body designed to reduce heat soak and promote steady air flow. When paired with an 8AN female fitting, it helps to draw larger volumes of air while maintaining filtration quality, which can support a crisper throttle feel and cleaner intake charges.

In practice, the combination of precise filtration and straighter flow reduces the chance of pulling hot air from the engine bay into the intake. The result is improved air handling for a cleaner intake charge, while the durable aluminum construction keeps weight down and resists corrosion in harsh environments. The filter’s low profile—2.2 inches tall and 2 inches wide—fits into tight engine bays without adding bulk.

Filtration performance is described as up to 95 percent efficiency, thanks to the fine mesh that captures fine particles without overly restricting air flow. This design helps to straighten the flow and reduce the intake of hot air from the engine bay, contributing to a more consistent air supply under varying driving conditions. The entire assembly is built for lightweight durability, combining aluminum alloy with chrome coating for long-term reliability in demanding environments.
