    The RPM Air Gap manifolds use the same technology as the "Victor" series competition intake. The open air space below the plenum and runners separates them from hot engine oil, resulting in a cooler air/fuel mixture going to the head. This cooler charge creates more power and improved performance. The Air Gap manifolds include rear water outlets, two distributor clamp locations and nitrous bosses. For square-bore carbs only. Available with a satin aluminum finish. For non-EGR provisions.

    • For off-road use only.
    • Manifolds fit 1978-86 small-blocks with two-piece rear main seal.
    • These high-performance items are not eligible for any further discounts or promotional pricing.
    • High Performance, designed to improve performance.
    • Find in OPGI's 2018 El Camino Catalog page 264.
