Cold Air Intake suggestions

[zMrManz]

So I just recently bought a 1987 MKIII Turbo in the hopes of learning some mechanical skills and getting a fast car at the same time. So one of my first thoughts was to get a cold air intake for it. I've looked around the forum a bit and found some articles on the subject, but none of them really got me the information I wanted.

I guess my question is what's some good cold air intakes that you guys have used? Was it worth your money or would you not consider doing it knowing what you have now. Also pics would be great too!

If there was a topic about this already and you could redirect me to it I would be glad to do that as well.

I am not aware of any aftermarket cold air systems for the MKIII Turbo.
The stock air filter intake pulls air from the space under the front headlight bucket and is quite effective. Having said that, many owners opt for a high flow filter (I use the AEM dry flow) and build a custom system.
One option is to route an intake tube all the way to the space under the right headlight bucket and put a filter on the end. This will get the filter out of the hot engine compartment enviroment.
Another is to build a box around your aftermarket filter and draw air from under the headlight like the stock system.
I have an air scoop mounted in the right corner of the grill. Flex hose is routed under the right head light to the cut out for the factory air intake. I do not consider a cold air intake, however, it does supply cooler air to the filter when driving.
I can take some pictures if interested.

I'll second that recommendation.

I prefer this setup as well. It's much less involved than building a box too.

Definitely not a preferred setup. While BARELY a step above just tossing a filter on the end of the AFM and leaving it open to the engine bay you're still leaving it open to the engine bay heat while the vehicle is at rest when the worst heat soak occurs. Depending on the number of bends and their angle you're probably not seeing any benefit that you would see by simply removing the passenger side fog light and forgetting the duct.

This is what I did for mine to help isolate the air coming in from the engine bay. Although it is a NA, the concept should work for a turbo as well. And as far as making the filter run under the headlight the only advice I would give is to keep it up as high as possible to prevent any chance of hydrolock. But maybe it does not rain that much where you are in utah.

You can add a valve to the intake piping to open if the vacuum goes above a certain value (say vac over 22InHg). OR they make cylindrical filters with a clamp on both ends which you can add to the pipe further down... they're small enough that little air will be pulled in through them as long as the primary filter isn't clogged or submerged (AEM makes one).

There is also the hydroshield by INJEN but I maybe just paranode. I hear alot about people hydrolocking motors on the 7th gen celica forum because the CAI sits so low.

I also noticed that there weren't many options for an intake as well. Which is unfortunate :/

This sounds interesting. How challenging would this setup be for me? I'm fairly new to this whole working on cars thing. I'm good for a challenge, but I also don't want to mess up my car either...

Also it doesn't rain too often here. But when it does, it rains hard. And this would be a daily driver as well.

Also another good thing to know is how much would each of these options cost me? I'd imagine now very much, but still good to know when weighing options.

EDIT:
@907MGE I also like your heat shield. That looks like a pretty do-able option for me as well.
