Description

Holley LS 2x4 dual plane fuel injection intake manifolds allow you to install dual throttle bodies on your late model LS Series engines. Their dual plane, equal-distribution layout produces great midrange torque without compromising top-end power. The manifolds feature all cast aluminum construction, a wide 1,500 to 7,000 rpm power band range, and can accept dual inline mounted 1,000 cfm throttle bodies with a 1.750 in. maximum throttle bore diameter.
