  • Item Description

    The ECU controls your injectors as a set. So if they are imbalanced at all, you will have some cylinders that are flowing slightly rich and some flowing slightly lean. The percentages are how closely the injectors are flow matched to one another. The closer that the injectors flow to one another, the more precise the entire fuel system will be which makes it more efficient. This improved efficiency manifests as better fuel mileage and a smoother engine.

    We offer an advanced 1% flow-matching service which also includes documentation of the flow-results for each injector. This is $80 for the advanced flow matching.

    As far as which option is correct, the choice is entirely up to the customer based on their individual needs and budget.

    *Please send us a message if you are interested in the 1% advanced flow-match BEFORE ORDERING*

    This is a flow-matched set of OEM Bosch UPGRADE professionally remanufactured fuel injection units.


    This set directly replaces the stock Rochester injectors. The injectors will look different from your stock injectors, but they have the same fitment from seal to seal and same flow rate as the stock injectors.

    CS Performance is anindustry leader in custom EFI technology. Our state-of-the-art factory usesonly ASNU flow benches in our certified ASNU service center. Our flowtechnicians areASE certified Master Mechanics,so you can feelconfident that your fuel injectors are being tested and rebuilt properly.

    Though we keep ourprices very competitive on eBay, it is important for our customers to know thatwhen they buy from CS Performance, they are still getting the same high qualityand genuine OEM brand cores that we have always offered to the public.Ourgoal since starting this business is to provide top quality auto parts tocustomers at a fraction of the price that they are at local auto parts stores.Thisis what has driven our business to success, and what keeps us going in thisincreasingly flooded market.

    Genuine OEM InjectorsVS. Chinese Aftermarket Parts:

    With the recent floodingof Chinese knockoff injectors that have reached the market, it has becomeincreasingly more important to separate our factory and products from thecompetition. Ebay currently groups all the products together and does not havethe technology or knowledge to know the difference between genuine OEM brandcore rebuilt fuel injectors versus Chinese knockoff "brand new" fuelinjectors. CS Performance is among the very few stores on eBay that providesquality, genuine fuel injectors that will have a flow match rate of 3% orbetter and will function like brand new. When comparing a rebuilt OEM fuelinjector with a "brand new" Chinese knockoff injector, the rebuiltOEM injector will always come ahead with a closer flow-match, precision lasercut nozzle plates, better atomization, and reliable functionality for years asopposed to days.

    If you have anyquestions, we are very happy to discuss the products we sell. Please do nothesitate to reach out to us.
