I am trying to decide on injectors, and most say to just go with 370's, but before I do anything...I would like to get a better idea of what injectors are available.

First, are 275's the same as 300's? Only difference being the 300 is for the marine engine?...so they are the same injector?

Second, where does the 330 fit in.

And is the 370 by itself...is it a marine injector, and if so...is there a smaller rated injector for auto use (like the 275/300).

Aftermarkets are another story...but I would like to start with trying to understand the Bosch injectors first. Thanks,

As far as I know, the 275/300/330 are all the same. The 370 is bigger. They are all marine injectors.

i have installed 300's and 370's. i will never install another set of 300's, they seem to smoke just as bad as the 370's and don't make as much power.

So unless other members say differently...as you guys have described...Bosch only offers two different "Sized" Injectors for the 12V, above the stock injector sizes that came in 12V's... 275/300/330 and 370.

So am I to understand that the "differences" in power people think they get between the 275's, 300's, and 330's...are really a figment of their imagination??...because there is no difference between the three of them??? Maybe this is why vendors never seem to get back to me, when I ask them this question.

MrSuzuki,

It does get confusing for sure. That's why we sell the "new" Bosch 12 valve injectors at a 70 and 90 HP increase info. That way you know what you are getting and don't have to guess etc.

i could be wrong here (happens from time to time) but i believe the 275's you are referring to are 24 valve injectors.
