ACURA RSX Type S 2.0L - DOHC i-VTEC 16 VALVE ( K20A2 ) - 2001 - Up

Designed for the enthusiast preparing a stock or mildly modified street engine, or a bracket racer seeking maximum value for his dollar, the Manley Performance or Street Series valves are the perfect choice. These dependable valves are also offered in Street Flo versions providing significant flow gains without head porting. All valves in both these series feature chrome stems, hard tips, swirl polished under head areas, and fully machined combustion faces.

Manley Performance is universally acknowledged as the leading manufacturer of performance and racing valves in the world.

The reason for Manley’s overwhelming success is simple: QUALITY. We offer the best materials in the industry - exclusive materials our competitors do not possess. Our stems are hard coated with .0002" thick chrome rather than a few millionths of flash. Our hard tips are superior to competitors’ puddled stellite which can crack and erode off the stem. Our valve head and under head shapes have been in the forefront of the quest for improved flow since the late 1960’s. And always each Manley valve has been price targeted to specific markets to ensure the best possible value to the customer.
