Save your money. An NA will see no benefit from sticking a short ram intake & a cone filter one it. Especially if you don't enclose the filter with a box of some kind to prevent sucking in hot radiator air.

ya i guess i could, i plan on doing turbo 2 swap so i was also wondering if the short ram with switch over to the turbo 2 motor??

Just mod your stock airbox and cut the air silencer out of it. The silencer is a huge restriction anyway.

On the air box cover, there is the duct that connects to the cold air duct to the front of the car. As you should be able to see by looking at it, the air has to make a 180* turn to get to the AFM intake from there. Cut that out so you just have an opening in the side of the airbox lid and you are good as gold.

No, it won't be the same thing. The turbo inlet is much smaller than the TB elbow on an NA.

If you remove the air duct, you'll just be pulling in hot radiator air from the side of the box. It's the same thing as with an open cone filter. The front of the duct seals against the hood and limits airflow to that from in front of the radiator only. The stock filter setup is fine on an NA. It would be fine on turbos as well if it wasn't for the horrible TID that twists all over the place to fit.

hmmm alright i guess is should start savin for a t2 than. thanks

jjwalker

I didnt say remove the air duct. I said to cut the ducting out of the INSIDE of the box. The duct extends far into the box causing air to take a 180* turn to reach the AFM inlet. I mean to cut the internal duct in the air box lid, while still retaining the external cold air duct.

Ah, I misinterpreted what you wrote. And this internal duct you mentioned must be an S5 only thing? None of my S4 boxes have it; just a flat lid.

go with the HKS intake, it is 50 state carb legal, and HKS is a great brand. I am borderline on getting one, tho it might raise speculation on more mods in my engine bay with police since i got some pretty stuff under the hood.

jjwalker

I guess so. The internal duct makes it way half way through the box. Before i modded the lid, only one side of my K&N would turn black while the other wouldn't even show signs of dirt ( side under the duct ). That tells you right there the air was making a 180* turn to reach the AFM inlet at the bottom of the box because it was directly beneath the occluded portion caused by the internal duct.

I actually gained a bit of engine response past 5k rpm cutting it out. Seemed to be...less choked I guess you'd say.

This weekend, I am going to duct the stock cold air tube to the high pressure area in front of the radiator. The stock inlet is all sealed up from this location, and since water is much heavier than air, water ingestion shouldn't be an issue unless I drive through a large body of water.

oh alright so you guys suggest the hks... well i need a turbo motor first sine it wont do anything on a N/A. maybe ill just cut the inlet like jjwalker said...oh man if i start cutting things up and makin my own parts pretty soon my car is gonna be VW statis

jjwalker

Nah, if you do it right and make it clean, your car won't look like a 16yr old Honda owner got a hold of it.

If that's really true, it sounds like a worthwhile modification. Could you post a picture of the inside of your modified airbox? Proper airbox mods / CAIs in most cars result in just a couple HP gained. Should be easy to demonstrate on a dyno by swapping a modded airbox with a stock unit.....

I have to go to work this morning and wont get off until late, but I am off tommorow and would be glad to post some pics.
