Hi all,
My 2005 3.0R Spec-B manual has developed a 'rattling' noise under full throttle acceleration when going up a hill. It's most noticeable around 3000rpm. From what I've read I'm pretty sure it's pinging. The car is stock apart from a KiDo tune.
After reading through some threads I checked my surge tank (also referred to as inlet plenum, airbox etc) and noticed it was cracked.
Anyway I picked up a replacement tank from a wrecker today. When I got it home it I noticed that mine has a kind of inner plastic shell with holes in it. The one I bough today doesn't have the shell.
Is the shell supposed to be there? Do all 3 litre H6's have them, or does it depend on the particular model?
I didn't try too hard but it doesn't look like it can be removed. I've installed the new box so will keep an ear out for the noise.
Any advice would be much appreciated!
My cracked unit on the left, replacement on the right.
