judging by markings and boxes, I believe I have junk parts.

 

This happens more and more. Note that the seller is in high change is a victim as well. (Well, in this case when no original markings on boxes, the warehouse employer should check and notice when parts have arrived on their stock. So sloppy material sourcing by them)

Every big manufacturer have process against for counterfeith now days.

 

There are tons of grey market parts. This actually happened to me recently, my valve covers came from a JAGUAR dealership to my independent shop. They had Magneti Marelli stamped on them, but FOMOCO made these for JLR. (unless a new parts supplier stepped in as MM is a legit mfg). They started leaking almost immediately and another shop had to tell me they had these markings on them. The original shop re-did the job at their warrantied expense and got new parts from Jaguar but grey market is a big deal.

In my past experience in factory automation, we had pallets of goods come into port in FACTORY SEALS only to discover after shipping to distributors/customers that they were either empty/stuffed or filled with junk equipment or equipment of similar likeness to get it to pass the weight/dims checks.

 

Wow, that's scary. Imagine an indy shop doing a 12 hour job with parts in an OES bag only to have a comeback a few months later and they have to eat that cost.

If something seems too good to be true, ask yourself "why?".

 

Well your right it was my fault! I know that 8 injectors for $300 is a deal but I stupidly went for it anyway!
As you said it was too good to be true.

I think Bosch can check these for you. Since they offer lifetime replacement on their injectors, I'm pretty sure they are serialized and as such can be cross checked with Bosch for their authenticity. It is a chore tho, so easier to get from authorized source to reduce the risk of fake parts.

 

FCP Euro warrants all their sales.

Oh nice. Reading is imperative on my part

 

Well, I went to my local AutoZone and got 4 new Bosch injectors with correct holograms on the box, correct markings on the injectors and the 4 injectors from AutoZone cost $250 more than 8 from FCP Euro. Got them installed and boom. No more problems. Car runs like a top now. So I would say that those were without a doubt fake, crap parts.

Thanks to everyone who helped me figure that out. I never would have figured out it was the brad new clone injectors that were the problem!

 

Good that you get your engine sorted.
I hope you get your money back from FCP Euro too.

 

Thanks for reporting back as I had always heard FCP was a legit parts seller with a good reputation? I am surprised you and FCP got caught with these counterfeit parts?
It happened to me too but with a different supplier so maybe more common that I had thought?

Yeah, I’m not sure. So far they’re not super responsive on my emails. I bought a set of 8 coils from them as well. Granted they’re not OEM Jaguar but the quality compared to OEM leaves MUCH to be desired. The rubber seal to keep water and other debris out of the coil it self is sealed tightly on the factory coil. On these things it’s like the rubber was just slid on and called good. Nothing is sealed up and I don’t trust that they will perform at an OEM level so I’m trying to get them to take those back too. At this point I don’t want anything they have to sell.

Unfortunate to say the least.

 

Sadly, confirming the deluge of fake parts from China swamping the market....and yes, the lack of an "H" for Hella is a definite giveaway.
Plugs are harder; The fake NGKs gave a numeral "0" rather than a capital letter "O" (or vice versa) and the corners of the hex are sharper than real ones,
other than that the only clue is the price 😣

 

You got it on price and unfortunately, I think there is some onus on us not to get trapped into fake parts. Meaning, if you find an "identical" part for 45-70% cheaper than anywhere else, I'd say there is a HIGH probability it's a fake. Look for good value, but not cheapest you can get as that's always trouble.
