Cold Air Intake 4 Mk3

[Supra2NR]

i tried to make myself a cold air intake system , evertthing was godd escept i cant atke out the airbox which basically ruins it for me i got the pipe where you can jus put the O2 sensor in and it all should be alright but one problem, it was made for toyotas 98 and up, now i was jus wondering if i buy a 98 up O2 sensor from a dealership and do they have the same amount of wires so i can jus simply remove the old sensor and put it in so i can complete my project or will this ruin the stock system on an 88 mk3 n/a
if possible tho what car would have similar wirings as a supra

The item in the photos is NOT an 02 sensor. It is the Mass Air Flow sensor. Your car won't run without it. It is a calibrated part. If it ever fails, you (probably) can use one from a different year.

02 sensor is in the exhaust manifold.

sorry about the confusion im new to this engine, but do i have any aftermarket options to remove the whole thing? does it restrict my airflow , and if it does what year and which car can i borrow parts from , and would it giv me the straight pipe that i want?

LOL.
You're stuck with the AFM. Unfortunately the car won't run without it, or extensive other mods (read: standalone)
It's easy to work around, so I don't know why it's a big deal. Just put the piping on the adapter that your filter bolts to, then clamp the filter on the end of the piping somewhere behind the fog light.

sorry kinda confused , can i jus bypass the afm , its not really a big deal to me , but i just one of those people that if its factory its not good enough for me he he , dunno why but i jus hav this obsession, that i want everything perfect

i hace pics on top, so what do you think with the temporary solution that i did you think thats good enough for now?

Well, I always wondered if you could put the AFM straight onto the throttlebody using a short hose. Then you could run a 4" CAI to the AFM intake side with a step down adaptor like the ones I saw at PepBoys and AutoZone that come with those cheap cone filters (1 size fits all).

And like said above, put the filter behind the headlight/fog light. Or even in front of the a/c condensor/intercooler.

those pipes from pepbys are 4 inches??, seriously, thats the one that i got installed from nopw since im tryin to find my solution to have my tru cold air intake, theyre decent from now , since the jackass that sold me a car had a unsealed black ceramick piping as an intake, and when i told him, about that he jus said its ok since im not boosting

[Supra2NR]

i moved the afm to the throttle body,
perks of the move

shorter tube, since i only used one 22 degree bend tube it looks like a short ram intake, so the lesser the air travels, the faster it will get to the engine, and its less likely to lose velocity

its close to the fan so cold ait is more likely to be sucked in by the filter, and it gets fanned when you drive, better performance with no cost, everybody likes that right?

theres more space in the spot where the old intake used to go , so more air inside the engine bay and more air to get sucked in by your intake.

and not like i thought b4 u dunt have to turn the afm upside down or anything the wiring reached just fine, all you have buy is the 22 degree bend tube from pepboys which costs about 9.99, and a few adapters,and clamps

one important thing is the 45 degree adapter that you are gonna use to connect the throttle body to the afm.

the post might seem a little disorganized , sorry for that but im jus happy that i did something good
hope this helps somebody


while youre doing the move i suggest that you clean the parts too especially the afm i got pics here and u can see the diffrence

Im really not trying to rain on your parade here but you should be aware of at least one thing...moving the air filter inboard of the radiator/fan like that will actually cause the intake to suck warm air...and as you probably know warm air is less dense than cold air. Therefore while in theory you might be getting more air flow you are actually getting less air density, thus less horsepower.

if you do a little research into intake set ups you will find that more people prefer the approach of getting cleaner colder air from outside the engine bay.

What I did for my setup is I used a conical filter that had an open top. I then fabricated some ducting that goes through the front (where the stock air cleaner originally got its air) and then using ducts from various cars (the most important one being the fresh air duct from an 89 ford F-250) I found in the junkyard, created a sort of a ram air scoop out front to catch more air at speed.

In summary, while your setup might look nice and all, dont expect it to noticably increase performance

[Supra2NR]

i know that too thats why i jus ran and got sum felxible tubing and it connects to the filter, and the other end i could jus put by the front bumper with a scoop so like you said i can catch more air. thats what i did with my cadillac b4, i know that theres not a really noticable diffrence in performance, but gimme a break, dont you feel better, when you do sumthing diffrent with your car?

but do you think this setup right now with the duct, which one do you think is more beneficial for me? the first one that i got with the afm in the end by the filter or the one that i got right now?

i love forums, without this i would have never had critique from people like u
