Which Air Filter Panel Should I Get For R34 GTT?

[DOUGMO]

I Have A Bmc Panel Filter,

Cheap And Effective Italian Made

Quality

[morlock]

I don't like the K&N filters cause they need to be oil'd to work effectively. Much prefer the HKS range of filters.... $80 for a panel filter so not to bad on the wallet.

Adam, in that case do I need to take it out for one big solid run? I'm usually around the city so there is no long and fast bits about it...

[GtstCoupe]

does any one know about the apexi flat panel filters ,and what would be the way to go.

nismo

apexi

bmc

in the range of panel filters.

[Abo Bob]

I don't think it's necessary but I did give it a burl tbh.

[satanic]

Well hopefully this filter comes soon so that I can get some decent time working it in before Show and Shine

[ricknismo]

I heard K & N is better...is this true?

[benl1981]

Dont bother wasting any petrol trying to run it in. If its going to make any difference it will just be a bit less restrictive so at e.g 4000rpm you may have a little more airflow, so ECU will add a little more fuel to increase power.

Ok, latest update on the Panel upgrade:

K&N panel filter (part no. 33-2031-2) went into the stock air box tonight (yes tonight. couldn't wait)...

Reset the ECU as instructed below; didn't even need to turn on any lights or press the brakes to get rid of remaining charge cause there was none (but did so anyway) - Stock ECU reset!

Then proceeded to replace factory filter with brand spankin new K&N unit... few wipes of the cloth, re-attach the airbox unit and voila!

Took the car out for a nice, hard drive - from Frenchs Forest to Belrose, to St Ives and back... total of about 20km averaging 100kmh (whoops)

Got back home and parked the car - but whilst sitting in it while revving in neutral I noticed a difference (more below)...

PERFORMANCE INCREASE:

As stated by most of you, yes there is a performance increase... of how much I can't really say but it is definitely noticable (I've got an Tiptronic so gear changes aren't as drastic)... would really like to know if there is anything else I should do to help this out?

THE ISSUE:

Revving the car in either Park or Neutral produces this weird phenomenon - the needle goes up to about 5k then drops back down to 1.5k all smoothly.

However, at 1.5k it seems to jolt slightly and pause before dropping back to 900 (normal idle)... There is both a visible jolt, a sound jolt and I dare say some jolt in the way the revs are really going down! Is this normal?

Overall I am quite happy with the upgrade... any comments or opinions on where I go next? Bear in mind that this is still pretty stock (apart from mods in signature)

Thanks everyone for all the assistance!

[ricknismo]

is the a/c on?

[satanic]

Air Conditioning was not on at all...

[Abo Bob]

Don't know about th problem but a cat back exhaust is next on the list.

[satanic]

Well hopefully this little problem goes away... maybe after some more driving so the ECU adapts even better to the new filter (Sunday's cruise should be perfect)

Adam, should I go cat-back or turbo back...

I have an HKS offer for a cat-back system for $300, the turbo back system would have to be from a retailer so it'll cost about $1k

[Abo Bob]

Turbo back is better but you can do it in stages if funds are restricted. Ie do cat back then cat then turbo to cat.

Try to get a split dump if possible, you will notice it above 6000rpm.

[mad34]

i have an apexi pod filter and its works great. Its very loud though. It was the first mod that i did and i really noticed the difference felt allot quicker.

[satanic]

In that case, should I just go for the HKS system and then go for a Front Pipe? That's what you're saying right?

NOISE FACTOR FOR PANEL:

I've noticed that there is a bit more noise, but it's primarily got to do with the turbo "wooshing" - nothing extreme!

[DOUGMO]

Get The Split Pipe,

Makes A Huge Difference

[satanic]

Can someone please post up a picture of this split pipe?

I'd also like to learn a little bit more about it - making decisions for a purchase very soon!
