By pass one of GMs dumb LS design flaws

It is worth it to bypass your dumb GM LS crossover to heat a throttle body. Get this and never look back. Will need pipe dope for the threads but that’s easy enough. Rip the old one out. Thread the flex hose into the ends so they both line up close to the same flat plane. Don’t be He-Man as these are fine threads into Aluminum. There is generally less than 15# of pressure in an engines cooling system. On a Chevy Express van they are terrible to get to so if you can get this and get er done. #weaverstonehousefarm #aaronweaveryourboilerguy @aaronweavertheboilerguy

Good buy.

Put it on a 5.3 with a ls6 intake and it worked great. Just use teflon tape so it doesn't leak coolant.

A must replace part for all LS vehicles

With the dreaded rusting of the crossover pipe, this is a great way to fix or eliminate the problem from happening. Recommends all LS engine owners to replace this ASAP.

it was better than the pics

it was better than what I saw in the pics

Great product and high quality

Great quality and worked well. Don’t forget to put Teflon tape around the threads.

Good quality and easy to install

Nice steam pipe replacement. Installation was easy. I installed mine to replace the block off pieces to the rear cylinder, which allows coolant to circulate in this high heat area.

Great buy!

Perfect fitment on my 99 5.3l
