Oreillys Part number 116 are the O-rings that match the OEM ones. I put some back in my OEM hoses to replace the ones I took out and put in the Dorman 90 connectors. I havent tested them as I am currently testing the OEM O-rings in my Dorman 90's and so far no leaks or coolant loss. Seems to be working fine.

 

I ordered the engine cover and coil covers together for like $80 bucks at Roush. I tried to find some separate, but most are as much as all.

Dorman 90's with the OEM O-rings did fine for 28 days no leaks and I decided to buy some 90's quick connects from Gates #28505 just to test these and their quality. The gates quality is definitely OEM and the O-rings are the same as the Original hoses. I currently have them on my truck testing them to see if they are going to leak or not. 8 days and so far no leaks.

 

Gates still soild and no leaks. I also installed these using the Gates power grip thermo plastic connectors using a heat gun. Part number for power grip connectors #32929
