Default MY99 intake

I know, I know...this subject has been beat to death, but...

I'm trying to design an intake system that will be the safest for my MAF. I bought the car in Oct 2000 and it had a Greddy airinx on it (don't ever get one of these) Anyway, It only took 2 months to blow the MAF. At the time, I had no idea what had happened. I hadn't heard about the problems with them then. I know better now. Since then, I have been running with the entire stock system, snorkus and all. I didn't want to take any chances until I knew I had a good system to go with. I still am not completely convinced, however I haven't heard about too many MAF's blown lately (knock on wood)

What I am thinking about is a "ram air", sort of. I want to get a drop in K&N for the stock box, a gasket for the torque box, and a tube coming from the intake on the front bumper to the stock air box. I still have to find a way to isolate the MAF from engine vibration, so I'm kinda leaning toward 3" silicone tube from MAF to an aluminum tube to the torque box. I know I will have to enlarge the intake on the torque box to 3"

My concern is that maybe the MAF can't handle the velocity of air that would be coming in the tube from the front bumper. I may just draw cold air from the fender well instead.

How's this sound? Any suggestions would be greatly appreciated.
Also, how many miles do you guys have with your intakes with no MAF failures?

Thanks~Bill

Might want to check out this thread I too have a MY99 and have yet to blow a MAF using many different intakes. I am getting ready to take a saw to a Cobb intake and make it work with the MAF Danzborin has had this for a couple months now with no ill effects so car Larry Ganz can point you in the right directions with either his Ganzflow or a Cobb and as far as limits on Air flow I have no idea but I think the MAF is more precise in measurement IIRC

I have a MRT foam filter near the fender and remove the 2nd filter near the throttle body......

save you $$$ and MAF and do a mod somewhere else..... you might as well buy some headers or some cams....

On the long run, it will be cheaper.....

Talk to Kartboy, he makes a MAF adapter which eliminates a lot of the vibration which causes the MAF to fail...... I don't remember with which intake system it works with......

Anything that Can fit up to the 3" opening on the Kartboy adapter will work I Have the Filter directly on the adapter works well.

mrbillydee,

I used to have a 3" dryer duct from Home Depot run from the triangle area of the front bumper into the first airbox. ( I removed the orange triangle thing to get more air ) I took out the tubing because above 5000rpm it would vibrate and drive me crazy and the fear of pulling in water was a bit much also. And the yellow airbag lines runs in that fender well. I do want to mention I had it on all summer long and never once did I have water problems. It's the "what if" that I kept thinking about.

Anyway, there was a noticable difference in power after 70 miles per hour. Anything under that I couldn't feel. I have an auto so that might be why. Atleast it was fresh cool air the engine was breathing. But while duct was there I could pull up long hills on my way home from work at 80mph, punch it and be up to triple digits in no time flat.

If there was only a way I could custom bend a 3" rubber tube to fit.

I wrapped my MAF and intake tube with Dynamat xtreme to kill the vibration.Thats why Dynamat is so exspensive,it works.Plus it acts to keep the temp inside the tubing down.I also put the dynamat on the inner fender wall and sealed the stock airbox so it ONLY pulls air in from inside the fender.Car pulls real nice.My next step will be to trash the filter in the box and mount one to the inner fender out of site.I will also completely seal off the fender so the only place air will come in is the little triangle opening and the only place for it to go is the airbox.

I dont suggest the ram air tube because when you are not moving at high speed you are asking for the car to pull air through the long tubing.

Thanks guys. That's exactly the kind of info I was looking for (isn't i-club great!!) I think I have ditched the "ram air" idea. Looks like the intake will be a fairly simple one, 3" aluminum tube from MAF to torque box, K&N filter in airbox and gasket in the torque box. I think I will also remove the orange triangles for more air. I also like the dynamat extreme idea. I've used this stuff for years for car stereo and it works great. Don't know why I haven't put 2&2 together yet I'll seal off the fender as well.

Thanks a lot!!

If I had a good idea of a place to host a pic of my setup I would post it but I dont know.


Ram air would work very very well ,but you would need a stand alone system to get it to perform.

Actually, My intake (MY99) is kinda funky I believe its a modified APC intake for a Civic, The previous owner had it on the car, and I recognized it when I went to Pep Boys...(although I think the curvy part was tweaked a little with . Whatever the case it works GREAT, and I think its like 65 bucks (correct me if Im wrong)

I posted a couple of pics when I first bought the car, but since then Ive custom fabricated a bracket that holds the system together with the engine so when I rev, the intake moves WITH the engine.... I marked it, hope you can see where..theres a free bolt (at least on my car =) )

Funny story, I was oiling the new filter yesterday, (KN filtercharger kit)

Shut the hood and drive off...30 minutes later my car wont pull over 3000 rpm .... I started to panic.. misfired , CEL flashing like crazy... it idled perfect though

Go back to the garage limping... (I was installing a Autometer Vaccuum boost gauge as well...and I thought I left a vacuum tube disconnected, )
after about half hour of throwing tools around my garage, I decide to take off the air filter.

The minute I did, a BIG puddle of oil drained out...

I ended up putting so much oil it coated the MAF...

Little gummout (after I took the whole intake apart, and wiped it down CLEAN!) and some revs cleaned it up...shes running great again.

BTW that intake has a perfect hole that was plugged up before....meter was a snap to put on.

Default ISR intake

ALl i have to say is the ISR intake is awesome. I got very nice gains and no MAF prob atall. I am now running STi motor mounts and treannymounts and still no prbolem. I have been running the ISR intake for atleast 20000 miles. It keeps the stock pendulum thingy the BIG BLACK BOX and i think that olays a big part in this WHOLE MAF conflict

Here is my ghetto setup, it work great Lots more power from 2000rpm up. I just did the SPG mod and it really helped the 5000+ range.
Changing the Elbow on the torque box is a must!
I also reccomend using a dry filter, and Beefy brackets.





I'm replacing the ABS parts with a ceramic coated Aluminum jobbie, and the cheap rubber connectors with silicone one's.

One comment,

I suggest bolting it to the engine/intake (the bracket) so the whole assembly moves as one... When you rev and the engine moves...it might (over time) weaken the bracket, pull on the intake, etc...

Costa, do you have a better pic of how you secured the MAF to the motor?

I just got the JC Sports Intake tube from another iclubber for a 2000/2001 (3 nipples). I fit it up last night, and everything fits about right, just need a little tweakin.
