Description

K&N Universal Apollo Black Cold Air Intake - 70mm Flange (RC-5052AB)

Boost horsepower and torque with the K&N Apollo Black Closed Induction Intake System. Features a 70mm flange, protective housing, and washable filter.

The K&N Apollo Closed Induction System (CIS) is a universal, high-efficiency cold air intake engineered to unlock hidden power in both naturally aspirated and turbocharged engines. Featuring a durable, lightweight injection-molded outer shell, the Apollo housing protects the internal filter element from ambient engine bay heat soak, channeling cooler, denser outside air directly into your intake tract for maximum oxygen delivery.

At the heart of the system is K&N’s legendary oiled cotton-gauze air filter, designed to provide high airflow while trapping microscopic harmful debris. The internal geometry is engineered to smooth out incoming air currents, minimizing turbulence and optimizing volumetric efficiency. Equipped with a universal 70mm (2.75 in) base flange, it integrates smoothly with custom ducting, flexible cold air hoses, or optional stepped adapters to fit a vast range of engine setups.

Best Uses

  1. Custom cold air intake upgrades for naturally aspirated engines up to 250 BHP.
  2. Forced induction and turbocharged applications up to 350 BHP requiring heat-shielded intake ducting.
  3. Performance project cars, track builds, and engine swaps where standard model-specific intakes cannot fit.
  4. Vehicles operating in warm engine compartments where isolating intake air from ambient heat is crucial.

Features

  1. Heat-Shielded Housing: Lightweight polypropylene outer shell protects the inner filter from engine bay heat soak.
  2. High-Flow Cotton Filter: Premium oiled 4-layer cotton gauze media engineered for high airflow and up to 99% filtration efficiency.
  3. Optimized Internal Flow: Smooth interior contours reduce turbulence and increase volumetric efficiency.
  4. Universal 70mm Base Flange: Built with a standard 70mm (2.75 in) outer diameter outlet flange for easy pairing with universal ducting or stepped adapters.
  5. Washable & Reusable: Removable internal filter element designed to be cleaned, oiled, and reused for long-term service.

Benefits

  1. Increased Horsepower & Acceleration: Delivers cooler, denser air to the engine for improved combustion power and faster throttle response.
  2. Prevents Heat Soak: The enclosed shell prevents hot radiator and engine bay air from degrading intake temperatures.
  3. Cost-Effective Lifetime Protection: Washable design eliminates the need to replace disposable paper filters, saving money over time.
  4. Versatile Custom Fitment: Universal layout adapts effortlessly to complex or tight engine bays across various makes and models.
  5. Reliable Engine Shielding: Advanced filtration media traps dust and debris, protecting vital internal components under high-stress driving conditions.
