The HKS Air Flow Less adapter can be used when the AFM has been removed, such as when using the Apexi Power FC D-Jetro or F-CON V Pro.
This makes the conversion to MAP based sensors much easier with an easy plug-and-play re-installation of the air filter with the new adapter. The adapter features a buffed finish and an air intake sensor temperature sensor port.
Features
- Enables easy conversion from AFM to MAP sensors
- Includes a buffed finish with HKS log and air intake sensor
- Available for a range of vehicles
Notes
Silvia SR20 model requires installation of an aftermarket intake kit for fitment, it cannot be used with the standard intake system.

HKS was founded in October 1973 by Hiroyuki Hasegawa, a former Yamaha engineer, and Goichi Kitagawa, with start-up capital from Sigma Automotive; the name comes from Hasegawa, Kitagawa and Sigma. It began in a small shed at the foot of Mount Fuji, in Fujinomiya, Shizuoka, and is still based there.
In 1974 HKS built one of the first bolt-on turbo kits, for the Nissan L20 engine in the Skyline, raising output from 115 to 160 PS. Turbocharging made its name; today it also makes exhausts, springs, shocks and coilover suspension, and it marked its 50th anniversary in 2023.
