I put the perrin one on my car.
If you know what your doing its a quick job.
If its the first time you have done something like this, then make sure you dont need to be anywhere, undo everything, lift the manifold off, and drop it in there.
I like the perrin one to be honest, quite rigid, well made, and fits easy.
Keep the standard diameter inlet, its more then adequate for big power, the idea is smoother air flow, and when it reaches the thinner part of the pipe the air velocity increases as it gets towards the compressor.(basic science)
There all much of the same, but some are built better then others.
