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 😊
