Precision Auto Injectors

Whether your Jeep is 10 years or 25 years old, you've got fuel injectors installed in your engine.  Unfortunately they're also the most commonly overlooked item on a maintenance schedule due to their high dealer cost.  Most can't pay to routinely replace @ $80-100 a piece when you have four, six, or eight of them!  Typically injectors are used until they're failing and that can be a long dwindling road.  We inherently get used to our vehicles and forget how good they once ran.  Chances are you are suffering from this.  

Advantages of running Bosch Fuel Injectors in your Jeep

The best part about swapping stock Siemens fuel injectors in your Jeep is that you don't need to wait for them to be failing to benefit.  Stock Jeep injectors were designed to have concentrated spray patterns so check out our video showing the differences in spray pattern for yourself. 

Most Jeep fuel injectors from the mid 1980s to mid-late 2000s were made by Siemens Deka.  Though Siemens makes some great injectors, there are flaws that make them prone to failures and poor spray patterns. 

Siemens First Generation Metal Bodied Fuel Injector Leaking at the Seam

That's right, there's actually a seam there that fails and causes the injector leak externally.  The Bosch injectors of the same generation had plastic molded over the metal body so even the older Bosch injectors don't do this.  Siemens learned from their mistakes and did away with the seam in their next generation of fuel injectors.

Siemens 1999+ Jeep Plastic Bodied Fuel Injectors are Prone to Cracking

Higher grade stainless cores of Bosch injectors makes this virtually impossible to happen.  The cracking failure of newer Siemens injectors is due to a lower grade stainless alloy used which eventually corrodes and causes the injector to swell.
