Bosch Fuel injector

I replaced a bad fuel injector last year on cyl 5 with a Bosch unit, ordered through FCP Euro as to not get a counterfeit. I removed/tested/cleaned all 5 original injectors and confirmed cyl 5 injector was dead.

Cons: injector failure
Vehicle: Volvo C30

It seems that lately they are not as concerned about removing the VW part numbers. I recently got a set of OE BOSCH injectors and they also had the VW part numbers on them. And they were significantly less expensive than buying from VW.

Pros: less expensive than VW
Vehicle: Volkswagen

I had to take off the fuel injector bracket on the ones in front of the oil filler cap. The injector is still hitting it and putting some pressure on it so I’m concerned the angle is now not spraying the same. I have Bosch 630cc in now and they require an adapter which is making it sit higher.

Cons: pressure on injector, angle changed

Just had to replace an injector on my '04 Park Ave Ultra. I replaced it with an OEM Bosch injector. The car runs like brand new now.

Pros: car runs like brand new

A few month after the gdi cleaner I started to get a couple misfire on cylinder 1 during startup. It was not bad enough to really noticed but would though an engine code then go away every other week. After some troubleshooting I came to the conclusion that is was probably my fuel injectors.

Cons: misfire on cylinder 1

I found a great deal on a set of new Bosch OEM fuel injectors on eBay. All 5 for only $200 shipped free. I put them in today. Took maybe an hour at the most.

Pros: great deal
