Hydraulic cam followers

Hi,

did some more research. INA produces hydraulic barrel tappets.
INA Deutschland | Branchen & Anwendungen | Standard Ventiltrieb

Porsche part number: 996 105 041 50.

There are 2 different parts available.
INA part number 265010 Ventilstößel (8 per package, 24 needed)
INA part number 420 0049 10 Ventilstößel (8 per package, 24 needed)

Please take a look in the INA parts online catalogue. Use navigation to switch between different engine types.

Example link: 986, 3.2, 252 HP

And i have to correct myself. INA produces the parts. Febi Bilstein distributes the INA hydraulic barrel tappets. See: Hydraulic cam followers

I recommend to buy from a local parts dealer, not from ebay.

Markus,
Great research as usual.
According to Auto Atlanta Porsche the Porsche part number was updated to
99610504172.
Using the 99610504172 in your excellent INA reference you provide this updated Porsche # is INA 268902 Ventilstößel or 420 0104 10 Ventilstößel
This crosses over to BGLA #HL6330 on Rock auto. So many 'translations' bothers me......
