Fast delivery and good quality part
Good quality snug fit. Works as should. Only issue I had was whe tightening oil cap back on the 18 ft-lb torque made this part slip. I used material to get a better grip and torqued slow but it still slip before the torque gauge read 18.5 No leaks! So it’s all good 😊
