IMHO an exposed pod filter like the Apexi intake or K&N pod may flow a little more air than the K&N panel filter but will suck in HOT air from your engine bay unless you construct a shroud around it and duct in cooler external air - which is kinda what the factory intake already does.

upgrading a factory airbox + filter to an exposed pod assembly may work well for the Nissan boys as their factory boxes are small so their gains from a pod upgrade are significant (hence they recommend it to everyone)

anyway, just my 2 cents. others on this forum may be more enlightened regarding airflow velocities, cfm rates, etc

What he said ^^

Basically, the factory airbox with an aftermarket panel filter (ie K & N seems to be the go) is the best option.

I have an apexi power intake with a custom airbox - there was only about ~5rwkw difference.

Toyota has spent millions on R&D for this car - there isn't a lot that can be improved IMO.

stock airbox with TRD or K&N filter mate...

unless you are getting it for the better sound it makes not performance, because the sound of an apexi power intake is sweet i must say

[sootie23]

my red mkiv used to have a 3 inch stainless intake pipe with a pod at the end of it, and no heat shield, if i touched it after a drive the pipe would be boiling hot, and it ran worse in hotter weather. on my new mkiv i have just added a k&n panel filter and the plastic pipes doesnt get nowhere near as hot and the car picks up gradually right through to redline, as compared to my red supra it would feel slightly boggy in low revs!'

overall, if u get pod, make a airbox or buy this>>>>>

its called 'max' air box. connects to stock front air scoop and has thermal wrap on all sides for keeping it cool. bit expensive though. 250 US dollars

or you could fabricate one yourself for a fraction of the price.

I've tried. Not as easy as you think.

[attachment=505:attachment]Also a question whats better one or two air cleaners??????

Id never seen this setup on a supra that can be bourght as one complete part......

( as it looks in the ad )

with the twins having a air filter each and all the pipes.......

I opted for an S&B pod filter, they sell for around $130 and guys I have spoken to have said they flow quite well. I also got Car Toys to do a custom heat shield for me, they did it about 2 years back now and I think they charged me about $120. They did a pretty good job, seals the pod from the engine perfectly. Now I just have to sort out some sort of new induction snorkel to deliver cold air straight to the pod. I could take some more close up pics if anyone is interested.

Looks like a good job indeed!

May I ask:
Do you have anything covering the exhaust manifold (ie a heat shield )? Reason I ask, is that the manifold would heat up while driving, and consequently heat the intake piping just after the pod and before the intake manifold... That would negate the purpose of the heat shield wouldnt it? - as the air in the pipe would be heated by the exhaust manifold anyway...

Ive noticed my intake piping (made of metal) is heating up quire considerably. This is due to the extractors getting so hot...

Your (and anyone else's) thoughts??

In this situation, the charged air passes through the intercooler so it may not be so bad.

Very nice setup!

Not from the pod...

Unless my eyes fail me...

I know its pointing out the obvious PK ( no offense meant by the way ) but his car is a Turb so air goes through Intercooler first. This helps alot so what little heat is transfered wont make much difference.Our problem with heat is caused by the compression thru a near Red Hot Turbo charger.

Its not like the air is sitting around in the manifold soaking up Gobs of heat before entering the engine. This would be same on your NA by the way. The important thing is to get the air entering the filter to be as cold as possible.

Not trying to flame you mate.

Damn we all jumped on this issue at the same time

Fresh air enters the pod, the fresh air then passes through the turbo and is pressurised, the pressurised air passes through cooler to be cooled and the cooled pressurised air enters the inlet manifold on the opposite side to the exhaust manifold.

Thanks fellas. Learning all the time...

p.s. It's ok Darren - I know your not flaming me. It's not like I'm gonna crack the shits and start abusing other people...

Flame away...... :hunter: :butcher:

Also, have you thought about applying a heat shield of some sort on the intake? As darren said, the heat on the piping won't have much effect as the air won’t have time to heat up. Plus where do you stop? The throttle body get bloody hot also. When I replaced the Cam cover seals, I removed the throttle body about 30 mins after driving and it was too hot to handle...

I know this it too late but this is what I want to do at our dyno day

1st Run: My Uni Filter Pod + Shroud
2nd Run: Stock Air box
3rd Run: Stock Air box with K & N panel or Uni filter pod without shroud.

That way we can determine what the gains really are...

Can I borrow someone's stock box with paper filter and K & N panel for the Dyno day?

A heat shield over the extractors is something I am considering doing to see if it has any effect at all.

Hot air is my enemy! (esp that coming from Darren when he talks :P )

You can use my stock airbox mate. And I think Kim said we could borrow his K&N panel.

I intend on doing the same.
