Thinking of getting a performance panel filter - just got the normal paper jobbie in at the moment. Is it worth going for a performance one? If so, which? The STI one or Green Cotton one? Also, where's the best place to get one?

I like the green filter, but I would not expect too much in the performance area.

Green for me. Had an STi one before that & a K&N before that. Nothing earth shattering between any of them...

I am also useing a Green panel filter. wanted a Cone but not many out their.
green comes highly recommended by many people

Can't the oil on the Green damage the MAF?

 

[stevem]

not if it's cleaned properly. Over oiling is the problem.

Any noticeable difference with the STI? Someone on scoobynet claiming some wild bhp/torque increases on a JDM engine using the STI filter....

The benefit would be minor - could even be masked by using different rolling roads.
Don't believe everything some people claim - even the manufacturers - although the combination of improved filter and exhaust does improve performance by, in my experience, 25bhp on the same engine in an Impreza.
But which did what I can't say.

On its own I would say you wouldnt notice, its just the cumulative affect of changing lots of things that gets the desired effect.

Plus it looks better than the original,shame you cant see it!!
