Hi and Hello:
I am curious and stomped. I ordered (4) BOSCH p/n 0 280 158 045 Fuel Injectors from IPDUSA, all black in color. IPD says "they are an upgrade to" the yellow top China made p/n 280150762 Fuel Injectors and will work in my application. The yellow top injectors have a wider shoulder compared to the BOSCH and fit tightly into the manifold. The O-rings are wider also and help create a tight fit at the discharge and fuel inlet ends. The BOSCH injector has smaller-rings and is somewhat "loose" in the manifold. If I start the car, I am sure of a gas leak. This is not good.

Who has experience with injectors? Keep the yellow type or use the BOSCH? Something is wrong. The yellow are a fraction of the cost of the BOSCH on Ebay.

Thx. Engine is B-230F. One of my injectors has high ohms reading so I thought I would install all new (total 4) injectors. Car only has 135k miles, low gas mileage, good compassion all 4 cylinders so lots of life left in the car.

Comments, thoughts??? I think I will stay with the yellow top injectors.....right?

Thx. long live DL-240 VOLVOs
