Dual Distributor Hold Downs
Sometimes the standard single distributor hold down is not enough. so we have provided dual distributor hold downs on all Hardin Marine intake manifolds.

Four Corner Water Ports
All Hardin Marine performance manifolds feature two extra water ports at the rear of the manifold, a feature normally only found in manifolds costing hundreds more. Some enthusiasts have found that plumbing a line between these two rear ports can reduce engine overheating. Many racers also find these ports to be an advantageous special feature for plumbing special additional water lines.

Other Special Features
