Are you looking for Best injectors for a 2003 5.9L Cummins?

How do you know that there are faulty injectors?

Primarily, does your engine exhibit some or all of these symptoms? If that is the case, it could be a diesel injector problem.

• White smoke emanating from the muffler. If you have got one or more diesel fuel injectors sticking shut, then the vehicle’s diesel engine is not going to get an adequate amount of diesel. This diesel shortage will cause the truck’s engine to starve for fuel and will be responsible for white smoke emanating from the muffler.
• Dark colored exhaust coming from the exhaust. If you’ve got one or more diesel injectors stuck open, then your vehicle’s diesel engine will receive too much diesel, resulting in lots of dark colored smoke coming from the muffler.
• Truck running poorly or not running at all. Bad diesel fuel injectors can cause the engine to not run or can cause substantial damage to the engine.
  Damage to the diesel engine could include damaged pistons, damaged cylinder walls, or could possibly result in the engine to completely fail.

What is the cause of diesel injector issues in 2003 5.9L Cummins Engines?

From time-to-time diesel fuel injectors go bad, most often due to bad diesel . When your injectors fail, the truck will possibly encounter a power shortage, lots of white colored or dark exhaust coming from the exhaust pipe, and there are times the truck won’t operate at all. Failure to repair bad diesel injectors can easily contribute to considerable engine damage, so it’s imperative to replace failing diesel fuel injectors without delay.

These are usual causes for diesel injectors to fail:

• Impurities and/or bad fuel – Bad injectors are most often prompted by bad fuel (impurities in the fuel,) which can clog up the injectors, causing them to stick open or closed.
• Water in fuel. Fuel and water really don’t work well together. When water gets in the truck’s diesel fuel, it can cause the fuel injector’s tip to shoot off, which could produce substantial harm in the engine.

OEM Injectors Versus High Performance Injectors

As you’re selecting new diesel injectors for your 2003 5.9L Cummins there’s no avoiding the need for to select betwixt “{stock} injectors” and “performance” injectors. The difference really comes down to what you are hoping to achieve.

Stock diesel fuel injectors are exactly what the title implies. These are injectors which are built to Original Equipment Manufacturer’s guidelines. The Surefire Stock Injectors that we manufacture and deliver at Taylor Diesel are validated and calibrated on O.E.M. qualified test benches to make certain that the performance that you will experience with the new oem fuel injectors will be exactly identical to the injectors that originated as part of your 2003 5.9L Cummins when it was newly acquired. All Surefire stock diesel fuel injectors include a 2 year warranty.

If you happen to be looking to improve the overall performance of your 2003 5.9L Cummins diesel engine, then you will certainly want to give consideration to changing to the Surefire High Performance diesel injectors. The high performance injectors come with a 1 year warranty and they are available in two variations:

• 30+ High Performance Fuel Injectors – Our 30+ High Performance provide 30 percent more diesel to your vehicle’s engine, producing an additional sixty HP at the rear wheels. All of the increase of horsepower will produce a noticeable upgrade in power. All of these high performance diesel injectors also have a 1 year peace of mind warranty.
• 60+ Performance Injectors – The 60+ shows that this injector provides 60% more fuel to the engine. This results in at least 120 more horsepower at the rear-wheel without any other modifications.

As backward as it could appear, you will find that there’s an extra major benefit of high performance diesel fuel injectors … they will actually increase your vehicle’s diesel economy. We’ve witnessed fuel economy increase by as much as five percent in trucks that we’ve installed high performance injectors in. Why? It might seem odd that high performance diesel fuel injectors which provide more diesel to the truck’s engine would result in your vehicle’s engine to burn less fuel overall, but that’s precisely what occurs. By supplying additional fuel to the truck’s engine at the correct timing and at the most appropriate RPMs, it instead forces the truck’s engine to run more efficiently, working less and consuming less diesel as a result. If you’re looking for a considerable general performance enhancement, incorporated with a good fuel expense savings, you may need to consider upgrading to Taylor Diesel’s Surefire 30+ or 60+ High Performance Diesel Fuel Injectors.

Regardless whether you’re attempting to find new diesel injectors designed to deliver original general performance, or you are in the market for quality high-performance injectors which will offer you a great deal more trailer towing power as well as race-winning potential at the race way, we have the exact diesel injector replacements that you have to have.

The decision between oem injectors and high performance diesel injectors is really an issue of personal preference. Are you looking for your truck to run at factory specifications or are you looking for a boost in power and overall performance? The answer to that question should lead your decision.
