Product Details

Remanufactured Multi Port Fuel Injector by GB Remanufacturing®. OE-quality or better performance at a reduced cost is what you'll get with this remanufactured multi-port fuel injector. This injector is an exact OEM replacement part, so it guarantees factory-like fit, form, and function.

GB Remanufacturing


  • Remanufactured OEM part, not similar or aftermarket substitute
  • Affordable alternative to a new OEM injector
  • Meets or exceeds OE quality
  • Ensures reliable and lasting operation
  • OE fit, form, and function
  • 100% tested to ensure OE-quality or better performance

The multi-port fuel injection (MPI) system was a significant improvement over the carburetor and throttle body injection systems it replaced as it provides much better fuel control. This system operates using one injector per cylinder positioned in the intake manifold above each intake valve. Fuel is injected onto the intake valve where it is mixed with the air and sent to the combustion chamber. A faulty multi-port fuel injector can lead to problems such as high emissions, decreased fuel economy, poor performance, etc. If you need a cost-effective solution to a faulty injector, GB Remanufacturing will meet all your demands.

With its extensive line of remanufactured fuel injectors, GB is just the ticket for drivers who expect reliable performance and don't want to pay high dealer costs. The experts at GB restore the part to a condition that is equal to, or often better than, that of a new OEM product by reusing the components that don't wear out and carefully replacing all faulty units. GB utilizes the latest cleaning equipment, ultrasonic baths, flow benches, and computers to ensure that every remanufactured fuel injector meets or exceeds OE requirements. Plus, GB carefully analyzes all failure modes and makes upgrades to prevent failure of the part in the future, so in many cases a GB Remanufacturing injector is better than new.

This multi-port fuel injector features the same fit, form, and function as the original part because all injectors remanufactured by GB are exact OEM replacement parts, not similar or aftermarket injectors. In the remanufacturing process, each injector is cleaned, degreased, and subjected to a coil resistance test. After that, the injector is ultrasonically cleaned using state of the art equipment, reversed/back flushed, and put through a battery of tests such as spray pattern, leak down, flow rate tests, etc. Before the technicians install new components and make a final inspection, each injector is polished, clear-coated, and lubricated.

Established in 1986 with headquarters in California, GB Remanufacturing® provides rebuilt OEM fuel injectors for both gasoline and diesel applications, injector components, and diesel electronics to the automotive aftermarket. GB is also a trusted supplier of new fuel delivery parts. Since it was founded as a small family owned company by Mike Kitching and his father, William, GB has steadily grown to become a worldwide supplier of fuel system parts and the largest remanufacturer of fuel injectors in the USA. When GB remanufactures a product, it carefully analyzes all of the failure modes and makes upgrades to prevent future failure of the part whenever possible. It utilizes state of the art specialized equipment, including proprietary tools, to ensure that its customers receive the most reliable product possible.


All GB fuel injectors and related products are warranted against any factory defects for 24 months, unlimited mileage. GB Remanufacturing's liability is limited to the replacement or repair of the defective part(s). No allowance will be made for labor, installation charges, or damage claims. Any evidence of tampering, abuse, or improper installation voids this warranty.

Magnuson-Moss Warranty Act:

The injectors came very quickly. Each was sealed in a vacuum packed bag with care. There were no problems at all, they work like new.

I would recommend this to everybody. This is a perfect fit for my car. I used it on my Toyota 4Runner. My vehicle gained its performance back and my gas mileage improved. It also comes with the seals, so no need to purchase a set of seals.

Highly Recommended
Got them today and they looked brand new. These are very good. Installed fuel injectors and my car backed to normal. I would buy them again, except I will never have problem with fuel injectors, because them will never fail. I highly recommend this company for any fuel injectors.
