This set of six injectors did not work out well for me in my situation
My 2010 Volvo XC60 was getting a P0306 code for detecting a Cylinder 6 misfire. I was told if you replace one injector you should replace them all for consistency. OEM Denso injectors are $280 new. EACH!
So I elected to try these reconditioned injectors that are sold as matched to within 3-5%. After replacing the old injectors with the reconditioned ones I purchased here, I got error codes for misfires on Cylinders 1 and 2 and the engine had trouble starting and had a low idle. However my Cylinder 6 misfire was gone.
So, I put the original injectors back in their original positions except for the Cylinder 6 reconditioned injector. The engine runs perfectly with no fault codes. Original problem solved.
I probably could have gotten away with only replacing the P0306 injector on Cylinder 6 with a new one. Now I have 5 reconditioned injectors, 2 of which cause fault codes for cylinder misfire in a box in my garage.
I drove the car nearly fifty miles during this process to insure I was giving the injectors a chance to settle in.
