If you own an LB7 Duramax, first things first, good choice! Secondly, you do not need to make any modifications to it, given that it is the fastest diesel car technology in the world. But if you really feel the need for it, and this completely depends on personal preference, starting at the very root of your problems(if any) would probably be the wisest thing to do. You might want to start by checking your car's fuel injectors.
Best fuel injectors for LB7 Duramax
1. Bosch LB7 Car Fuel Injector
As the name suggests, these car fuel injectors from bosch are marketed to be compatible with the LB7 Duramax which makes the filtration process easier. You can be assured that these fuel injectors will fit right into your truck's system.
The bosch brand by itself has the credibility to attract buyers. Bosch has been around for ages and has delivered some of the best car replacement parts to ever have entered the market. The brand name should be reassuring enough to convince anyone of the quality of the product. These are more on the expensive end of the spectrum owing to the brand name, but there are a couple of reasons why buying these is always going to be a good option.
The first and foremost reason is that these are OE certified which means these pretty much compare to the fuel injectors of the base model of your car. Now do not be alarmed, by compare we mean in terms of placement and size specification.
So these fuel injectors are the same as the ones you had before but only better. Another great thing about these fuel injectors is the fact that the ball seats are made up of hardened chrome which goes a long way when it comes to durability. As chrome is pretty much corrosion-resistant, this factor helps prevent internal corrosion of the product which later on leads to expensive repairs and replacements.
The fuel injectors have solved the age-old problem of cracking that almost all of the injectors on the LB7 have. These come in a set inclusive of all the hardware required during installation, like O rings and copper crush washers. Overall, these fuel injectors make for a pretty solid choice and are going to solve all of your injector related issues in a jiffy.
2. Bostech De651 Silver Series Remanufactured Fuel Injector
If you are looking for fuel injectors that function decently without burning a hole through your pocket, then the Bostech De651 is the one for you. This fuel injector is one of the most inexpensive fuel injectors you can find anywhere these days. The low price point does not necessarily mean you will be compromising on quality. The low price point comes from the product being refurbished but that is in no way a cause of concern.
To prove credibility and reassure the buyers of the quality of these injectors, they come with a warranty of about 13 months. The fuel injectors follow OE guidelines which means that they will fit right into your car. The installation and compatibility of these products will never be a problem. New seals and O rings are a part of the whole package that is this fuel injector.
The only potential downside is that these fuel injectors are sold individually and not in sets because they are remanufactured. So, you might sometimes have to wait for them to come back in stock to finish your entire set. While this is a nonissue on most days, it is still worth considering. All in all, for the price that you pay, you get a product of the quality you would only get if you were to pay much more. This is simply an easy choice for someone with a small budget.
3. Bosch 0986435502 Stock Replacement Injector 01-04 6.6l Gm Duramax LB7

To add to the party, the internal parts are completely new leaving only the outer casing which is refurbished. This effectively brings down the cost without affecting the durability. The injector's body is supposedly crack resistant and can undergo a lot of pressure without giving in. the balls and seats are made up of chrome which just adds to the whole sustainability parade.
An added advantage of having this fuel injector is that you do not have to worry about the quality of fuel that goes into your truck. This is because these injectors use fuel filters of the highest quality which prevents internalized corrosion and gradual decaying of the fuel injectors.
The only downside again is the fact that these are sold individually only and do not come in sets. Regardless of that, for the kind of deal you are getting with buying this product, there isn't much room left for doubts.
