So far seems to be perfect. I did flip the center section so it's just black. But assemble loose and tighten everything up on the motor and fit perfect. I'm building another ls and will get another one.

This thing is junk. Yes, it looks good. But it leaks at all of the flare end connections. I had to pull my intake manifold and replace this kit, antifreeze leaked at 9 connections. Didn’t matter how tight the connections were. Don’t waste your time. My truck: a 2006 Silverado 3500 4WD LQ4 6.0.

every thing fit without any modifications. just need to be careful to place the right pipes in the right spot. Does not come with gaskets, need to buy them.

The media could not be loaded. I installed this on my engine and came out good and fits truck intake without any adjustment and fits nice and sturdy let’s see how it does running but for now five stars 🔥🔥🔥 I’m sure it’ll be good

I ordered this kit hoping it would fit under a Trail Blazer Super Sport intake manifold. It doesn't fit. I ordered some 1/4" stainless steel tube and made my own bends and flares so the union would fit down against the cover plate. Looks pretty nice and fits very well. Having all the fittings and the union all in one kit made it easier.

Absolute garbage. Spend the extra for a quality kit. Multiple leaks due to poor quality flares. Hard pass. Buy once cry once and do the motion kit.

I retract my previous statement there are two types, one with gaskets and one with rings. This product works great!!(Have to do extra work or order a different brand now due to the leak that will occur if this is installed with no o rings.)

Not difficult to figure out the arrangement for the lines. Fit was not perfect but with a little persuasion it fits and functions
