Product Details

The Airflow Research (AFR) 6324 is a premium CNC-ported aluminum cylinder head engineered for high-performance and racing applications. AFR's cylinder heads are renowned in the performance aftermarket for their exceptional airflow characteristics, precision CNC machining, and out-of-the-box race-ready quality — delivering significant power gains over stock cast-iron or OEM-style heads.

Key Features:

  • CNC-Ported Runners: Fully CNC-machined intake and exhaust ports for optimized airflow velocity and volume
  • Aluminum Construction: Lightweight, high-strength aluminum alloy reduces overall engine weight and improves heat dissipation
  • High-Flow Design: Superior intake and exhaust flow numbers compared to factory cylinder heads, supporting significant horsepower increases
  • Precision Combustion Chambers: CNC-machined combustion chambers ensure consistent volume and promote efficient combustion
  • Premium Valve Train Components: Assembled with high-quality valves, springs, retainers, and seals suitable for street and strip use
  • Race-Ready Finish: Each head is inspected and finished to exacting tolerances for immediate installation

AFR cylinder heads are a trusted choice among engine builders, professional racers, and serious performance enthusiasts. The AFR 6324 is designed to maximize power output while maintaining streetability, making it an ideal upgrade for builds targeting increased horsepower and torque.

Great price cheapest around super fast shipping will go to for all other performance parts needs!!!!!

Thanks

Very fast shipping, always great prices.

After shopping around for a specific cargo carrier, Autoplicity had the best total price by over $50 and great ratings, so I gave them a try. I received the SportRack Aero XL - A90275 last Thursday and am VERY impressed with their price and service. The cargo carrier arrived quickly (ordered Sat, rec'd Thurs) and in fine shape. I will recommend Autoplicity to my friends, and plan to shop with them for my future automotive needs.

Wanted to buy my parts on another audtion site but found the price much better on Autoplicity, and the service seems friendly.

Very pleased with product and shipping prices. Best price on the internet.Took a few to many days between order placement and shipping. Once the product was shipped the timing was very good.Talked with support-they were helpful and friendly.
