I have ordered a new APEXi intake kit for my 89 GTU. I'll be replacing the OEM intake and was wondering if anyone had any advice from lessons learned, or know of anything I should be aware of. It is on its way so I'm just killing time and thought I'd put this out for anyone that has experienced the change out.

I searched several forums and was surprised that there was nothing about intake changeouts on any of them. This is probably the most common mod I've seen and seems to be pretty straight forward and pretty easy to do. That is why I wanted to check here to find out what I can from y'all before I start the changeout.

The one thing that really prompted this is that I checked my air filter a couple of weeks ago and found about a half pound of dry dog food stored on top of the air filter! Didn't know my black lab and his brother were that mechanically gifted and was surprised that they had thought ahead and socked some food away for a rainy day!

It's basically remove the old filter and box and replace with the new one.
It's pretty straight-forward and probably why there is no write-up.

Dog food in the wrong places is automatic flag for rats or mice making a nest.

Do those $200 intakes really do *that* much of a differece Ted?

RETed

No.
People are all caught up with that RevSpeed article posted on that Supra site, and now they think they are getting the best performance.

I've read that article in person, and what's bad is the Supra site doesn't post the dyno runs of each air filter.
The A'PEXi does make the highest PEAK ps value, but it did not have the highest powerband across RPM.

Follow up, I have also noticed that there is a small 1" hose coming ut of the bottom of the OEM air filter box that runs to the air pump, I think. I have noticed that people have put a small cone air filter on this hose to filter that air as well. Is this a stock item or one that comes with the Apexi kit?

What y'all are saying is that this change is not worth the money? I've heard it is highly recommended as performance enhancer.

IMHO, to get any real performance benefits you need to upgrade to a more freely flowing exhaust setup. air in == air out --> air++ in == air++ out

lmao. c'mon man. it's an intake. imo it hardly qualifies as a 'performance enhcancer.' a turbo is a performance enhancer.

even with the best intake you get a little more air, maybe some miniscule hp/tq gains. for a FC i suppose it could free up a lot of space under the hood, which imo is probably the best reason to get one.

imo buying an $200 intake kit is a waste of money. i would fabricate my own to save $$$.

my thoughts are go with whatever intake setup you want but realize that you will need to make some sort of ducting of fresh air b/c whatever gains you will get from the filter will be underminded by all the hot engine bay air. ive tried a few different filters and i think that a k&n drop in filter is better than a cone filter without any sort of fresh air supply. there are a few ways in the archives on how to make a cheap, if not free, fresh air duct. also for the air pump hose just get a little breather filter at pepboys i think it's diameter is 1 inch.

so ted, if the apexi intake doesn't have good powerband, then what intake do u recommend to us?

Kenteth

umm... Air in does *NOT* equal air out.

Take highschool chemistry...

GTUser

thanks for answering my question. I'll check the Pepboys out for the breather and I will be building the cold air intake once I figure out the install. As I said in my intro, the main reason I wanted the Intake is that I found about a half pound of dry dog food on top of the stock air filter when I checked it at the last oil change, the extra room in the bay will also be nice.

gtuser,
I just got the kit you've got and mine had a hose to run from the adapter to the air pump. Also I wanted to know if all the brackets mounted right. If you got the lower long bracket to fit let me know how.

i just put an Apexi intake in a month or two ago and i did get the lower bracket to fit. took me like 20 mins to figure out, but its a tight squeeze. if i can find my camera i'll take a picture.

drago86

how do you clean the apexi filter?

GregSL-SE

tigerclaw- thanks that'd be cool
drago86- there's no need to

ShIvER[PT]

I've read b4 that it doesn't need cleaning.. but how can that be ?
I mean.. the dust that it filtrates has to go somewhere !!

GregSL-SE

All I know is that it is a maintanence free filter. Those particles will collect on the outside and I guess you could knock it off gently if needed? Good question anyone else.

drago86

I dont understand,.... how can it not need cleaning,..,... it either filters crap out, and thus eventually clogs itself,.. or lets crap through and doesnt clog,.. unless its self cleaning somehow.......

RETed

Yeah, I didn't understand that either.
There is no such thing as a "maintenance free filter".

Received the A'PEXi intake this week and installed it Wednesday night. All the information and instructions that came with the kit were in Japanese. We're real men and we don't need no stinkin' instructions.

Once I figured out how to orient the filter on the AFM it was very simple to installed. The adapter plate had the air pump hose and its fitting was behind the filter so I didn't need the small air breather for it. Also the custom brackets helped mount and stabilize the intake using the OEM air box mounts.

I have an S5 so I couldn't find the appropriate mounting place to use the long bracket. I assumed that it should go from the bottom of the adapter to someplace on the fender or front of the engine bay. Could find any mounting points within reach of the bracket. Post pics if you found where to put it post a couple. I will praise you as a genius. The few english instructions implied that all the brackets may not be needed for every application.

I installed this on my car and it was simple. I'll snap some pix when I get home. The long bracket you are taking about goes on the bottom of the filter with the small part of the L facing forward and bolting to the sheet metal behind where the shield for the headlight wires are.

BTW my instructions were in japanese as well but there are only so many ways the brackets could work.

GTUser

Went out and checked the engine bay and found the screw with the grounding wire. Now to stretch the bracket to fit both mounting points.

GregSL-SE

yeah I didn't want to bend it to fit but thought maybe I was missing something.
ilike2eatricers-yeah post that pic. did you have s4 or s5?
andrewdruiz- that's great, mine was $45 more but how does that help us install ours??

s5 t2 bump this thread later tonight or I will forget.
