HPS Performance 837-579R 837 Series Cold Air Intake Kit Red

The HPS Performance 837 Series Cold Air Intake Kit (Part # 837-579R) is a free-flowing 2-3/4 inch mandrel-bent aluminum tube induction system engineered to replace the factory restrictive air box. By relocating the air filter outside the engine compartment, this cold air intake (CAI) delivers cooler, denser air to the combustion chamber to increase horsepower, torque, and improve throttle response — all while maintaining a safe air-fuel ratio. No ECU tuning is required after installation, and the kit will not trigger a check engine light (CEL).

Key Features:

• Bolt-on installation — no modifications required; includes a step-by-step manual with clear pictures
• Convertible design — can be reconfigured as a short ram intake
• 2-3/4 inch mandrel-bent aluminum intake tube — lightweight, heat-dissipating, and built for long-term durability
• HPS race-proven reinforced silicone couplers — high-temperature rated for reliable performance under demanding conditions
• Industrial-grade 100% stainless steel T-bolt clamps — corrosion-resistant and secure
• Washable and reusable HPS Performance air filter (Part # HPS-4275) — excellent filtration without restricting airflow
• Fine-tuned to deliver maximum power output through the top-end power band
• Not legal for sale or use in California — not CARB exempt
