First of all I want to say it is not my style to bash or talk bad about vendors we all make mistakes so I prefer to give them a chance and also the benefit of the doubt. Unfortunately, this situation needs to be public so that the vendor will either improve (which is what I hope for) or others can be warned and not have the same financial loss, loss of time, or potential damages that I have experienced.
I bought a MMP PI kit on 07/2017 that was part of the Precision Raceworks Elite Fueling Solution. The port injection kit came with the famous “fomoco” injectors MMP has became known for having quality issues with leaking, not working, not flowing correct, etc. On January this year my build was at the point I needed to install the fueling system, so I had my mechanic do the work and install the kit.
After install of the kit they could not get the car to run right and I spent money having to have them figure out what was wrong. Ultimately, we decided it was possibly the injectors, but I did not want to blame MMP for bad injectors instead I sent them to an injector service company. The results came back that the injectors were flowing more than 28% apart! Bosch OEM standards are 5% and performance injector companies flow within 2%. In addition, his marketing claimed these were 750cc injectors but as you see below some only flow half of that and none are near 750cc. The highest injector flowed 48% less than advertised!
Actual injector flow numbers sent to MMP
Injector 1 460 cc
Injector 2 395 cc
Injector 3 475 cc
Injector 4 415 cc
Injector 5 370 cc
Injector 6 450 cc
With that info I contacted MMP with my problems and provided the flow data as well. The response I got was “I sell injectors now that are matched to within 1% and made by Bosch OEM. They are more expensive injectors. I can sell you a set for $375.”. In response to this I sent Mauricio a second email explaining again that the kit was less than a year old. I am the original purchaser. And the injectors were only in the car for a month, so these injectors were like this new out of the box. I asked if there is not a warranty or courtesy that could be used to make this right?
In response he stated “I have some other injectors here that are within 5% that I can sell you for $200 at a discount. They are not Bosch but are good injectors. Bosch spec is within 5% as well. To get within 1% requires testing and matching above an beyond Bosch spec.”. I was very disappointed that now he was trying to sell me fake Bosch injectors (why does he have these anyways?) and has not once addressed the fact that my injectors were defective. He wants to make money is all he wants he doesn’t care that it is his fault not mine that I need injectors in the first place. Proper quality control or not selling injectors that you know have issues to save a buck and drive profits then making the customer eat it is not right.
As a final hope I reached out to Precision Raceworks who I purchased the kit through. They reached out to MMP and explained the situation again and copied me. They basically told Precision Raceworks they don’t care (this is the exact reply).
“Here is the warranty policy posted on our website https://mmp-e.com/pages/mmp-store-policies”
I have went back and forth trying to decide if I should post the reply email Precision Raceworks sent to MMP (Mauricio) and ultimately decided I should. This is to keep there from being anyone saying “MMP wouldn’t do that they have good customer service”. The way they typed the email is what I had been trying to say but English is not my first language I am not from the USA.
Mauricio,
The customer did not receive what was paid for and this is a known issue by both you and the rest of the BMW community. We will replace the injectors ourselves if that is what is needed to make the customer whole but would first like to give you the chance to reconsider your stance. The injectors included in his kit do not meet the advertised information provided to us or what was listed on your website. Asking the customer to pay for this is very poor customer service. This is not a standard warranty situation this is a situation of the customer provided payment for a product and the product was not as advertised. Furthermore, the customer has spent time and money to discover the issue was that he did not receive what he paid for.
You know what the right thing to do is please let us know if you will step up to the plate and do it. If you won’t we will simply do it for the customer and eat the $380. But this is a simple situation where the customer deserves to receive what he paid for.
Best Regards,
PR Sales Team
After that email MMP / Mauricio started working with me. They agreed to send free replacement injectors if I paid $45 shipping. I was glad to see MMP was willing to make the situation right finally and more than happy to pay $45 to get my issue resolved.
Well guess what showed up at my doorstep…. Knockoff Bosch Injectors from China…
There are several ways to inspect injectors to confirm they are China Fakes you can find more on the internet if you like but the easiest was what I found below. Fake injectors out of China use a brass ringed “filter” inside the injector which was their work around for assembly (if you remove this filter the injector is trash). Bosch does not and has never used this filter and are fully serviceable. Also Bosch has never printed 800cc on their injectors like shown in the first photo (this was what started the google search to see if these were fakes).
Anyways I learned my lesson and will not be supporting a company that misleads, misrepresents, and refuses to take responsibility. I did everything in my power to work with them only to waste more money and more time getting more low-quality product as replacements. I am sharing this so that others can know the truth about MMP and Mauricio. Hopefully they change their policy and improve quality, so they can be a good business. I however will not buy from MMP again as I can’t support any person or business that knowingly misleads customers with false marketing and poor-quality control.
