R32 Pod Filter & Air Box Questions

[playboi14]

Hey guys,

Just wondering if any of you would be able to answer I question I have about my R32 GTS-T

when I bought the car it came with a generic aftermarket pod filter, it was pretty old and crap looking (plus a defect)

I finally managed to get a standard R32 air box and replaced the pod filter with the standard box (plus a new air filter).

However, when I drive now the sound of my Blow Off Valve is almost inaudible.

When I had my old pod filter, the sound was extremely loud, and from 2,200 revs up I could hear the build up, and on release at 3 - 4,000 revs it would make a loud hiss / vacuum sound. With the standard air box in its almost 1/4th the volume of what it used to sound like.

It actually runs better and smoother on the standard air box, but I just don't understand why changing a pod filter to the standard air box would make such a drastic difference.

Would anyone be able to explain this to me? I double checked all of the hoses and clamps, and there is no leak anywhere, and the turbo still acts exactly as it used to (in terms of build up and pressure), just the sound has changed.

Would really like to know if this is normal or if I could have damaged something.

Regards

absolutely normal. airbox is doing it correctly and quietening down bov noises. most people do this to avoid unwanted attention.

suggest getting a good panel filter to keep same or better flow (then pod) of air to turbo... stock panel filters are a little restrictive.

Pods are crap imo, unless they are correctly shielded they are basically a hot air intake.

What u deacribed is 100% normal, as when u have a pod ur basically amplifying the intake noise.

Thanks for the quick reply guys!

That makes me feel much better as it sounds like I didn't break anything in the process of putting in the standard Air Box.

The old pod filter that I removed was a 'Tenzo Filter', and it also had a large black shield that would cover the sides. Is the old filter something I should keep a hold of? I removed the Boss kit (the adapter from the Air Flow Meter to the base of the filter), the Pod filter itself, and the metal shield that went around it.

These things worth anything? should I throw it on Ebay or try and sell it here?

The air filter I put inside the standard box was just a regular one I got from Supercheap Auto (that suits the R32).

are there any good brands that will make a difference? Also if it is an enclosed box, would any other filter really make a noticeable difference?

Thanks again guys for the quick reply!

I am using a k&n hi flow panel filter in my 32. Mine was around the $100 dollar mark, but is a lifetime filter

I also use a k&n filter in my airbox. Just don't use an oiled filter as it will mess up your air flow meter constantly.

^^^ I am yet to have a problem with an oiled filter in either of my 33s, my now gone VL and my mates S14. Going on 6 months now and AFM still looks exactly the same inside and works like it should.

i did the same mod on my 32 with a stock airbox and a hks panell filter no turbo flutter and when i hook the bov no bov noise.... glad to hear that this a normal outcome
