Also here is some good info. Doing research on the factory 3rd gen EXL OEM tensioner if you look closely at the hydraulic end of the tensioner and the bearings the whole assembly is made by Ina. So I went on RockAuto and clicked on all of the tensioners listed and blew up the pictures to compare them to OEM. What I found is that the Continental 49439 has the same EXACT brand markings as OEM it has the same identical markings on the bearing and the hydraulic unit and the casting on the back of the tensioner has engraving inaf238248.02 exactly as a Honda oem branded unit but of course at a considerably less price. RockAuto shows it at 96.79 and 104.78 shipped to texas. I called my local Honda dealer they wanted $250. So for those looking to buy a OEM tensioner check out the Continental. I also looked at the gates and dayco and ACDelco and none of them have the same Ina brand markings as the Continental and Oem Honda. This is in reference to the honda Oem part number 31170-R70-A01 and Continental 49439.
