Hi all! Working on making my first spark plug change in my 2014 3.4 l Cayman S.
It seems there are two ways I can go in purchasing these plugs.
First way is to go with Porsche labeled spark plugs with a part number of 999 - 170 - 151 - 90.
Second way is to go with Bosch OEM fgr5nqe04/0242245581.
The second way is one-third the price of the first way.
Does anyone know if these are the same spark plugs and if there is any reason I should go for the Porsche label spark plugs?
Also does anyone know if both of these are the correct fitment for a 2014 981 Cayman S 3.4 l?
Thank you very much and happy Motoring before the rain comes!
Aloha, David Loux
