oil filler cap
 

Does anyone know where I can buy an aftermarket oil filler cap for a 986? Thanks :)

Buy an OEM Porsche cap from Sunset. Can't be more than $20. If the cap does not seal right, you'll get a CEL.

Why exactly do you want an aftermarket cap? What's wrong with the OEM cap?

the one i have seems to be leaking pressure. If i push it really hard the cap gets really loose so i am looking into a new one. I didn't know if they have one out there on the market that's not plastic? I just picked up my first porsche about 2 months ago so i am pretty new to this still. I recall switching to titanium oil filler caps in my previous imports that i drove. Thanks for the help guys! :)

Why do you want a titanium cap? It'll burn your hands if anything. Stick with OEM.
