ABOUT THIS PRODUCT

The standard plenum top throttle body flange has a 105 mm opening to work with throttle body part number 112-581 or similar models. The top-feed plenum base intake manifold is designed with a reduced overall height to fit under a stock or mildly modified hood. The Lo-Ram provides a low profile modular intake manifold suitable for use with plenum mounted air-to-water intercoolers for boosted applications. Various Hi-Ram plenum top options are available to compliment the top-feed base intake manifold kits and fabrication flanges are offered to aid the fabrication of plenum tops for custom installations. Available for OE direct fuel injection only and with port fuel injection provisions.
