Show original supplier description
The K&N RC-5052AL Apollo CIS (Cold Intake System) is a universal air intake designed to provide increased airflow and performance for your vehicle's engine. This system utilizes a high-flow cotton gauze filter, known for its efficiency in capturing contaminants while allowing maximum air passage. The filter is housed in a durable blue polypropylene casing, contributing to its overall robust construction. Key specifications include a 70mm outer diameter (OD) base flange, which is the standard connection point. This design ensures compatibility with a variety of intake setups. For applications requiring different tube sizes, K&N offers optional stepped adapters, allowing for a more customized fit. This versatility makes the RC-5052AL a adaptable choice for many engine builds. While K&N does not specify exact horsepower or torque gains for this universal kit, cold air intakes are generally engineered to improve engine breathing, potentially leading to better throttle response and a slight increase in power, especially for normally aspirated engines up to 250BHP and turbo engines up to 350BHP. The 'Apollo CIS' designation indicates a closed intake system, which helps to draw cooler air from outside the engine bay, further enhancing performance.
