Upgrade your Acura TSX with a JDM high compression K24A engine — imported directly from Japan and hand-selected by J-Spec Auto Sports. This engine is the perfect replacement or performance upgrade for your 2003–2008 Acura TSX, featuring true 3-lobe VTEC engagement and higher compression pistons compared to U.S. domestic models.
