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

Doesnt fit under holly single plan manifold and quality is lacking

So far the kit looks good except one of the fittings didn’t have its threads tapped and was unusable

Overall the kit works, however you need to be aware of 1 thing… if you just tighten down the 90* fittings in the junction block, they will contact each other eliminating a true 4 corner kit. I trimmed a few threads off the fittings and reinstalled. With the trimming, there was open clearance and we have a true 4 corner steam port kit. If they can address the clearance issues then it’s a 5 star kit for the money. Till then 4 stars as you need to do some fine tuning.

Beyond impressed and couldn't wait to write this review. Fits perfect! Install loose and tighten at the end. 2002 silverado with a LS1. Let me reiterate, it fits perfect! If you have to bend anything, you have installed it wrong. Stays low to the valley plate and fits under the truck intake by a mile. HIGHLY recommend, can't beat this price.This is an important piece along with a catch can on any LS build. Cheap insurance!
