Twin 3" Air Intake Filters

[streetracer]

I was woundering if any one has done this to a KA24de engine or not and if so what was the out come. Was it good or was it crap and should not have been done.I have searched and did not find any thing about a Twin air intake filters.If some one has a link that has this please let me know.

Uh, what is the application? You'll have to dink around with a custom intake manifold. Finding the space would be hard...I'm thinking the gains would be minimal if anything at all. You might even loose power, because you're sucking the air slower (flow is mostly the same, but area is increased => smaller air speed). Plus you've got all that extra weight...Seems like it's not so good, as an idea. Inline engines, especiallly 4-bangers don't need 2 intakes.

would you need two mafs?

[elgarvo616]

if you make a Y out of the piping, you could put the MAF in before the split.

[Raxephon]

Is this what you're thinking of?

[streetracer]

Thats what i was thinking of.

Would definately be noisier than the oem airbox, but not sure of the flow characteristics of it since I don't own one.

I was considering it for my Q45, ( my airbox is missing clips).

The spongebob filters scare me a little though

[maxnix]

Would be dirtier also.

IMO for a KA motor, it would be pointless, except for the ooh-ah factor.

on a 4.5L v8, with 300+hp....might be a little more benefical with a set of better quality filters.

I dont think anything under 4.0L would benefit from having more than one fitler.

In fact, some factory airboxes have built in resonators, and what not to actually increase airflow than some open pipe. Dont you ever wonder what all thoes extra boxes/plastic tubes are on your factory intake?

it should be noted that dual air filters are available for z32tt cars with BIG POWER. this is way after the turbo upgrades. but then the gtr's used dual maf's and filters.

For dual turbos...

[s13sr20chris]

exactly...i was trying to gently nudge in the direction of reality.

[Exar-Kun]

the KA will NOT flow enough to be limited by a good free-flow filter, evne boosted. period.

Most twin-intake system are for cars pulling in enough air to concave a single filter( over 600hp, some WELL over it)... a KA is never going to do that without methanol or something insane, and at that point..why run an air filter at all?

Just out of cruiosity, is there any logic to you wanting to do this? There's far better ways to spend money ona KA than trying to get two itnake filters on it...

as mentioned before, the only cars I can think of this evne being remotely beneficial on would be Twin Turbo Supras (and trust me, i've seen 800hp ones with a single turbo and SINGLE air filter...), Z32's, and Z33's(the latter because of coveineince, not flow limitations)

Those are built in to quiet the intake and to cause more turbulence. If those extra "boxes/plastic tubes" increased air flow why would we switch to a new intake without them?

I always thought they were there for trapping small woodland creatures

[240marcuSX]

Ive read that those kinds of filters dont actually filter as well as the standard cone type filter.

I know this is old, but two intakes could be used to overcome a small MAF. Two identical intakes could be used with a MAF only on one. The two merge after the MAF. Granted, the MAF signal precision gets cut in half and the possibility that the two pipes flow differs, but it does work.

Yes, and you end up running lean due to the ecu registering only half the volume of air thats actually entering the motor.

HOLY necro post

always wanted 2 do that
