ICT BilletLS Stacked Coolant Steam Crossover Tube for 3 Bolt DBC DBW Gen 3 Throttle Body Stainless Steel Braided Hose Kit LS1 LSX LM7 LR4 LQ4 LS6 L59 LQ9 LM4 L33 551675

It worked great and looks great as well!

These steam vent lines work very well on my 2002 Silverado 5.3/LM7 engine. I also added a two port steam vent line kit on the rear of the engine. My engine came from the factory with the two rear vent holes capped off so there was NO cross over flow from the factory. Both sets of steam lines from this seller look great and function as they should. Those here who had problems with leakage may not have tightened the connections tight enough. I used some teflon tape to help tighten them as well as insurance for a leak free connection. I recommend this product. John. EDIT- 2.5 years and over 17,000 down the road and these steam lines are still working as they should. No leaks, no problems at all. John

Great product. Second time I’ve used this crossover. Perfect option if you need to reroute your coolant crossover/vent line or just want to bypass your throttlebody

Great quality. Have a couple of ICT Billet items on my car, no disappointment from any of their products

Came exactly as it was listed on ICT website

I’ve purchased-items from ICT AND NEVER HAD AND ISSUES GREAT USA MADE PARTS AND THEY HAVE GREAT CUSTOMER SERVICE

Got this too move the steam port to the passenger side of the engine for my LS swap. Worked perfect

This product doesn't hold up it will leak even with the GM brand thread sealant. I also ran into issues of it causing my engine to over heat. Total waste of money by the time I installed and realized it was junk it was to late to return m.
