Hi

I have just fitted a battery relocation kit ( Spec R ) and have noticed a strange sound coming from the air box...

When I rev. up to about 4-5000 rpm and the let off. It sounds like a fluttering noise which I believe to be the MAF..

Is this normal as before I fitted the relocation kit I could hear nothing?

What you're probably hearing is the dump valve working now that you've straightened out the pipework routes. Some people hear the same thing after fitting an induction kit.

It is definitely coming from the air box.... and not the dump valve…

So is it because the pipe is now shorter and straighter that the MAF makes this noise or do I need a new MAF?

The sound WILL come from the airbox because that is where the nearest open end is from the dump valve return into the intake.

Why would it be the MAF. It is a fixed construction and doesn't have anything in it to make a noise like you describe.
