842-12243 Fuel Injector

Bought these due to having a small leak on one of my factory injectors. Replaced all six with these and had nothing but problems with them. Poor quality. Several had glue smeared all over the injector body. One had part of the old o-ring embedded in the groove with a new one over top. The car immediately started having issues starting. Smelled like it was running rich. After one week I took them back out to find every new spark plug completely fouled. Spray pattern is incorrect and spraying too much fuel. They are unusable and likely damaged the cat as well. Cleaned and installed the original injectors and the problem was solved. Caused a headache for a week trying to solve a problem caused by these injectors. Stay away from these.
