2015-2016 Chevrolet / GMC Deluxe Max Air Flow Bundle HSP DieselLooking for a kit that has it all?

Looking for a kit that has it all? Featuring a mandrel bent 4 inch intake tube for massive air flow gains, with HSP's signature heat shield box eliminating unwanted hot air entering the cold air intake. For every 1 degree increase of intake air temperature will result in a 3hp loss. This kit also features HSP's high flow turbo mouthpiece.

This turbo mouthpiece will give you the ability to reroute your factory PCV system and remove the factory resonator box, eliminating unwanted engine oil gumming up the turbo and intake system. Featuring 3 inch mandrel bent hot side and cold side tubes with our max flow Y-bridge and turbo mouthpiece.

The factory hot side intercooler tube on your 2011-2016 Duramax is notorious for failure. The two piece design from the factory has crimped on boots that have a tendency to fail under heat and pressure, it's only a matter of time before it leaves you on the side of the road.

The factory cold side also has its limitations and is made of plastic with an unreliable clamping system. This kit replaces all the failure prone piping and will come with our race proven 5 layer silicone boots to give you years of worry free driving. Companied with our Max flow Y-bridge and turbo mouthpiece you can expect to see gains in performance while keeping engine temps down.

To help get the exhaust gases out of the engine, this kit includes our factory replacement 2 inch up pipes. Our up pipes use .120 inch wall tubing with the toughest bellows on the market to ensure they last as long as your truck. Also included is our factory replacement coolant tank to keep your engine bay looking good. Our coolant tank features an all aluminum design with an incorporated low coolant sensor.

To top it all off we added our upper coolant tube to add a little extra color to your engine bay. This tube will also give additional room for dual pumps eliminating the possibility of the hose rubbing the wheel.

A good value for the money.
Number of Items: 1
Chair was very easy to assemble. It is a lightweight chair but not cheap. I find it comfortable and the controls work well. Extra bolts are provided which is a great feature. I find the adjustable back support excellent, the head rest moves a little to easily, but it is easy to adjust while sitting.

Overall good chair for a good price
Number of Items: 1
Comfortable chair, but there's a very slight lean. I haven't yet managed to track down what's causing it, but as I slowly spin around, I find myself tilting slightly forward, then left, then back, then right... I've removed the casters and then removed/reinstalled the "ring" of legs, so the next place to check is the connection between the post and seat.

The chair is great quality, sturdy, and was easy to put together. Looks just like the photos and video. It is SUPER comfortable - the most comfortable chair ever! If you’re looking to purchase an office chair/ desk chair - this is the one! The price was reasonable and I would 100% recommend!

Great chair, only one issue.
Number of Items: 1
As someone who is exactly 6ft tall, this chair is just about perfect for my height and body type. High quality materials, adjustable lumbar support, very ergonomic. Visually, it works well with my desk setup. It has already helped me improve my posture ten-fold. My only complaint might be that the tension on the recline joint is too much. Twisting it to the loosest setting doesn’t feel loose enough, you’ll need to put your feet up on something to recline comfortably and stay in that position. Other than that, great chair. I don’t see myself returning this one.
