Cusco Direct Injection Coil Pack Set Subaru 2004-2021 STI

Compared to the single spark of the stock ignition coil, this generates four sparks in millisecond intervals at low to medium revolutions (1,000 to 4,000 rpm), significantly improving ignition performance. By significantly increasing the number of coil turns, combustion efficiency is improved with up to 46% more spark energy (for EJ engines) than the stock, even at high revolutions where the system switches to a single spark.

Features:
- Increased Power and torque response across the entire range from low to high RPMs
- Improved Engine Star
- Ultra-compact multi-spark unit built into the direct ignition coil body.
- No modification is required for installation. OEM replacement type
- Compatible with OEM ECU, aftermarket ECU, sub-computer/full computer.
