The RPM “Air Gap” manifold uses 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 manifold includes rear water outlets, two distributor clamp locations and nitrous bosses. For square-bore carbs only. Non-EGR.
