Right just fitted a new air feed for my pipercross and while i was there i am going to replace the standard pipe leading from the engine and connecting to the standard cold air feed. I hope you understand where i mean. anyway the pipe is old and knakcerd so i thought i would replace it but the old one has 2 holes drilled in it, also the same on another similar clio so do i need these holes? what are they for?
Cheers
Edd
