AFR Introduces Versatile New Plastic Intakes For SBC Engines

Plastic intake manifold intake technology has been a part of the high performance landscape for more than a decade, as Ford has employed them in their modular engines, while GM has done likewise with their LS family of engines. So, while Airflow Research’s new plastic intake manifold offerings are nothing new, their modular design is rather unique.

AFR’s new composite plastic manifolds feature an interchangeable runner design with a standard baseplate, upon which a different runner layout of the single-plane or dual-plane variety can be bolted to, making this a very versatile setup.

The compression limiters in the baseplate sticks out beyond the plastic, eliminating the possibility of over-tightening. The plastic construction creates a much cooler air/fuel mixture, while reducing the weight by ten pounds from a comparable cast intake, while running up to 30 degrees cooler than its aluminum counterpart. This all equates to upwards of a 15 horsepower and 15 ft-lbs of torque increase.

This intake is currently available for Chevrolet Small Block engines, with Big Block and Small Block Ford and LS versions coming in the future.

  • 15-plus horsepower and torque compared to competing manifolds
  • Composite plastic manifold runs 30-degrees cooler then aluminum counterparts
  • Weighs 9-11-pounds less than aluminum
  • Modular design with interchangeable runners
  • Reduces carburetor vibration by 5%
  • Rubber Viton gaskets eliminates leaks
