Review on 🔧 ICT Billet LS Coolant Steam Crossover Tube 3 Bolt DBC DBW Gen 3 Throttle Body Stainless Steel Braided Hose Kit LS1 LSX LM7 LR4 LQ4 LS6 L59 LQ9 LM4 L33 551675 by Mitch Wright

These steam lines work very well on my 2002 Silverado 5.3/LM7 engine. I also added a dual port vapor release kit on the back of the motor. My engine came from the factory with two rear vents covered with covers so there was no cross flow from the factory. Both vapor lines from this seller look good and work properly. Those here who have had leakage issues may not have tightened the connections enough. I used teflon tape to tighten them and also to insure the connection against leaks. I recommend this product. John
