Has anyone had any experience with INA lifters, or would you stick to Genuine?

 

Hi, yes I installed it, works fine, as I saw in mercedes original package they put the same

 

So Ina is the OE supplier for Mercedes Benz?

Does anyone know if Elring is the supplier for the head bolts?

 

it is

 

Is that a yes to both questions?

 

Does anyone know about the manufacturer of the head bolts? My catalog shows Elring. I would like to know for sure before I order a set for my car.

 

Has anyone used the INA lifers instead of the genuine lifters? Any feedback on them?
Fcpeuro notes that INA make the lifters as OE for the M156

It would save me a tonne to order INA lifters and Elring headbolts.

 

INA seems to be an original equipment supplier for Lifters
However, these INA (non-MB AMG branded) Lifters may be spec'd slightly differently than the MB AMG branded/spec'd Lifters in regards to anti-friction coating on the top surface, etc.
The MB AMG branded Lifters have undergone a few updates (2-3, i believe) since their inception to improve durability, in terms of this coating, and hydraulic design. Not sure the INA units feature the same updates.
These Lifters (especially older designs) are known to be prone to a certain, particular wear on the surface as well, which is postulated by master tech Tasos Moschatos to be attributed to camshaft lobes that have roughened/sharpened over time.
