Industrial Injection S475 2nd Gen Turbo Kit 03-07 Dodge 5.9L CumminsThe factory turbo found on the 03 07 Cummins is capable of supporting sub 450 horsepower levels. Above this point, it is being oversped that will result in failure, as well as the fact it simply cannot supply enough air to support horsepower levels above this point. Further, the placement of the factory turbo is not positioned in an ideal position as its centered on cylinders four and five as opposed to three and four, resulting in the front cylinders

The factory turbo found on the 03-07 Cummins is capable of supporting sub-450 horsepower levels. Above this point, it is being oversped that will result in failure, as well as the fact it simply cannot supply enough air to support horsepower levels above this point. Further, the placement of the factory turbo is not positioned in an ideal position as its centered on cylinders four and five as opposed to three and four, resulting in the front cylinders running hotter than the rear.

So, what's the fix? Easy, this turbo and installation kit from Industrial Injection to improve airflow and square the turbo on the engine!

And now, lets talk about the turbo. Industrial Injection has done a LOT of research on turbo sizing. This particular S475 on a 5.9L will work best when used in conjunction with custom tuning and a larger set of injectors for power levels above 800 rear wheel horsepower to deliver maximum street and track performance.

Turbo Options - The standard turbo kit will utilize a 1.10 A/R exhaust housing which is great for maximum boost levels and low drive pressure. However, if you're running minimal injector size (around 150), oversized tires, 3.42 or 3.73 gears, etc., you would be better suited to run a smaller A/R ratio, such as a 0.90, to actually increase drive pressure to assist in turbo spool. But if you're somewhere in the middle, say running 180 horsepower injectors, 35" tires, 3.73 gears, and daily drive the truck, you may be best suited for the 1.00 A/R housing.

Alright, its time to stop messing around with smaller, bolt-on turbo upgrades. You want big power and you need the right turbo to get you there. No, we're not talking about 500 horsepower, or even 600, you want 800 plus ponies lighting up the pavement, and this turbo kit is what you need to get you there.

A product that will make a difference!
Color: White, Size: King (Pack of 2)
These king-size pillows are incredibly comfortable and supportive. They are soft enough to feel luxurious, yet they provide great support for my head and neck throughout the night. The king size is perfect for a larger bed and gives the bed a full, hotel-like appearance. The pillows keep their shape well and fluff up nicely after use. I've been sleeping much better since getting them and would definitely recommend them to anyone looking for quality, comfortable pillows.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.

Soft, fluffy and surprisingly comfortable
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
I really liked these pillows. I tried to show different things in my photos because I wanted people to see the details: the design, how fluffy they are, and how full and thick they actually look. They are so full that the pillowcase even looks tight once you put it on, which I actually loved because they look luxurious and well-filled. At first glance they look very thick and high, but once you lay down they feel soft and fluffy instead of hard. They adjust comfortably and feel very cozy whether you’re sleeping, relaxing, or even reading before bed. I think they offer a really good balance because they feel supportive without being stiff. Of course, pillow preference is very personal—some people like lower pillows and others like higher ones—but for someone who likes fuller pillows that are still soft and comfortable, these are great. They are spacious, cozy, and feel like a very good purchase overall. I honestly don’t have any complaints so far. Definitely happy with them.
