The Economy Series Injectors feature OEM quality components, and provide you with a very mild 10HP - 20HP increase. For the best quality and performance, DDP balances each set for smoother operation and improved throttle response. These injectors deliver little to no smoke with excellent MPG. Great for stock trucks.
