Inlet manifold /plenum
 

would anybody be interested in an inlet manifold/plenum chamber that works but is just a little bit noisey when the power valve is open ( can still feel the little boost of power at 3.5k revs)

And how much would it be worth?

forgot to mention its still on the car and car has been fitted with a catch tank

It's a lottery to be honest mate, how long will it last? I have three in my garage in various states of disrepair and I only paid for postage. They are for future developments ;)
