Default Inyector for Corvette c7 2014

Hello everyone, I have a question about buying injectors.

I'm from Peru, and the mechanic told me my car needs new injectors.

He told me he can get them for $1,760 USD, but that seems very expensive.

I found the injectors on Amazon at

Amazon Amazon

My question is:

Did I make a good purchase?

Why are the injectors they want to sell me for $1,760 USD, and I found them on Amazon for $112 USD?

Please help me before I buy those injectors.

Thank you.


I attach my injectors actually

Millions of cars have injectors. Nothing magic about them. Get them from a reputable company. If you are good at working on engines, not that big of deal to replace them. There are DIY's that will help you. For $120 and your trouble might be worth trying. I had mine off and replaced them. From the look of your injectors there might something else you are overlooking. Are you using the correct fuel, oil ETC.

There aren't any in Peru.

Where could I get them?

The mechanic told me he can get them for $1,700.

Should I trust him?


What would happen if I bought it from Amazon?

Approximately how many kilometers would it last?

According to the mechanic, the problem is the injectors.

After maintenance, two of them are not working, and the others are leaking fuel unevenly.

This is a company I've used and a lot of racers use for cleaning, testing, balance flowing and/or repairing injectors. I have used them many times for my LS engines, haven't needed them for the Corvette (yet). You may want to reach out to them and see about having yours serviced and the faulty ones repaired/replaced. They will send you a flow sheet when they return your injectors. It's definitely worth a call

IF he stands by them, sure.

It's cheap FOR A REASON.

Maintenance? As in cleaning and testing with a flow bench?

Try THIS guy. He sells new and "rebuilt" injectors. By "rebuilt" they flow them, take the filter out if they can replace it, clean it and retest. I have sent him injectors I tested on a flow bench for cleaning (Bosch) so I knew what they were like. His "before" report was reasonably close to my report. He got them done and I tested them when I got it back and his "after" report was also close to my testing. He even found one of my injectors had a collapsed filter that was messing up the flow. Of course, I didn't tell him I had access to a tech college flow bench.
