Are there any differences in bosch marine 370s from different vendors. I see city diesel has them for $330 other vendors are all $400.

 

probably spray pattern. marine 370s have the wrong spray pattern for truck engines which makes em less efficient, makes your truck smoke like a train, and can ruin mileage

 

New era diesel sells 370s with the correct spray pattern.

 

Bosch Marine 370's should all be the same. Its when vendors start modifying them is where changes come in. 370's are a budget injector, like jammer tips for the 24v. Can't expect to get big power and have it clean for $400.

 

New era's aren't that much more $$$
