A'PEXi is a Japanese tuning specialist best known for pioneering electronics and engine management, including the legendary Power FC ECU, the AVC-R boost controller and the RSM rev/speed meter. The range also covers Power Intake filters, N1 and GT-Spec exhaust systems, and coilover suspension. A'PEXi's blend of smart electronics and proven hardware made it a defining name in 1990s and 2000s JDM tuning. Black Hawk Japan stocks the full A'PEXi range, sourced direct from Japan.
