The Nexus S2 provides faster processing, on-board Wi-Fi, and integrated wideband control, making it the ideal choice for turbocharged or high-compression K-series builds.
Complete Control & Connectivity
Designed for 2002-2005 EP3 and 2002-2004 DC5 models, this kit installs easily into the factory location. The Nexus S2 supports full i-VTEC control, allowing you to maximize the power band.
