Deatschwerks performs flow balancing and quality assurance testing on every set of injectors they produce, ensuring that the end product is top-notch. Deatschwerks injectors are tested and analyzed at over 40 data points on DW’s in-house New Age Technologies injector flow bench. Deatschwerks injectors are remanufactured by DW to the specified flow; you can rest assured that you are receiving a top-quality, reliable, well-performing product at a price that is hard to pass up.
