Founded in 1970 by Ken Sperling, Air Flow Research pioneered the process of CNC porting cylinders heads which is now common practice in today's automotive industry. Over the last 45 years we have been defining technological leadership and flow dynamics in the pursuit of increased performance. This commitment has enabled Air Flow Research to find themselves on the fastest race cars and the most powerful street machines in the country.

Utilizing modern manufacturing techniques and the latest in machinery, such as a Browne & Sharpe Coordinate Measuring Machine, fifteen Haas’ 5-AXIS CNC machines, three Mazaks, two Newen Epoch machines and a Mori Seiki 32 pallet system, AFR stays true to this commitment by manufacturing each piece in our Valencia, California facility just 30 minutes north of Los Angeles.
