Default Siemens/Mototron Shorty 60 lb./hr injectors

These are plug and play (mechanically) right?

Nope... those in the picture have a "car" style plug. The height of the injectors loosk about right... but the plug is not a "truck" plug. Woudl still require a injector pigtail conversion.

You will need spacers also. They are shorter than the truck injectors.

Hmm, OK...along the lines of Yelo's post, what injectors require no modifications and have a greater rate of flow than stockers. I'm looking for 42-60lb injectors.

As always, thanks!

What's all involved with the spacers? Is it just simple tube spacers to support the injectors? I've been reading up on this subject a good bit lately, but can't seem to dig up the information I remember when I was looking into this a year or so back.

Are all mototron 60lb/ hr high impedance injectors the same? Or are there different connectors or applications??
There is one that states "shorty" and the other does not. Are they the same? Will either style work for us??

We need a Multec II type injector. The car styles are Bosch style injectors. I'm not sure what the Mototron are but, they're not Multec II's.

If you want to go to injectors bigger than 44lbs/hr(rated at 4bar) it's best to go straight to a bosch style(car) injector. The Mototrons are shorter than the truck injectors if I remember right which might make swapping them in harder than using the bosch style injector. The Bosch style is the best way as there are LOTS of options out there for injector size.

Here is the injector conversion write up I did a while back.
