PVC Cold Air Intake! [PICS+VID] - Toyota Nation Forum : Toyota Car and Truck Forums

Added Cold Air Intake, OCT2009
Finally made the jump to a full-on Cold Air Intake. Sure it's just PVC piping, but as we all know, no one makes CARB-tested aftermarket cold air intakes for the Camry. Sure, the other option is to chop up a cold air intake from a Civic, but I decided to go the cheap route, and I went with this.

It was pretty easy to do; I've been thinking it might be fun to maybe mass-assemble a bunch of these and possibly sell them to other TN members, complete with a detailed instruction book. What do you guys think?

Big ups to JCamry94, who designed and provided the piping!

Shots from the front bumper:

In the engine bay:

Past the battery, under the fuseboxes, and through the car's chassi:

And out into the front-left wheel well, which closed up quite nicely:

I made it a point to add screws to sections of the piping that tended to disconnect easily (the two connectors on the opposite ends of the straight pipe), and to make sure the air intake temperature sensor was secure:

A re-bent paper clip to give the duct tape more surface area to help hold the sensor in. Call it ricer, call it whatever you want; this setup is perfectly functional, reliable, and cheap!

What do you guys think?

you should post a DIY

bigbird · 12-01-2009, 07:15 PM

nice man, thought id replace that tape asap. it will dry and fall apart quick in the engine bay.

good work

After you replace the tape, maybe buy some simple green and take it down to the power wash to clean your engine bay a bit?

Just giving you a hard time. Nice DIY, looks like it works good. Really though, clean that sucker!

Id buy one

NIce work nesquik

. I just wanted to let you know that I saw your video on Youtube of the evolution of your intake and it really inspired me to go with a Spectre setup. Hopefully with a little more research Ill make the move and buy it so that i can be able to hear my "beast" lol

I thought of doing a CAI over a simple ram but won't having an induction pipe that low cause you to suck up a lot of debris and dirt. I imagine moisture too when it rains.. In Chicago it would get clogged in winter from all the snow. Just wondering if you have any info on this?

sounds good man, nice video.

Nice work. Sounds good!!!

Nice vid too. For the IAT sensor you have taped, you could remove the gromett from your stock air box. Drill a hole in the pvc and fit the gromett, then plug in your sensor. I had to do this with my WEPR short ram for the paseo since they sent it with no hole drilled in it to mount the IAT.

Unfortunately, there isn't much you can do if you live in an area with such adverse weather conditions... At the very least, try to make it so the filter is mounted relatively high, so it doesn't suck up water or snow that may collect in the area inside the bumper in front of the wheel well. Aside from that, perhaps a semi-CAI would be the best option for you.

On a side note, thanks for all the feedback everyone! I hope you all enjoy the video I made. And I'll definitely look into all the suggestions for securely mounting the IAT sensor!

Very nice, good job, tho I can't hear the video for some reason...I'll listen when I get home!

Jimnist · 12-02-2009, 09:26 AM

If any part of the PVC starts melting/if you smell burning PVC, bin the entire thing and go back to the SRI. Burning PVC emits toxic fumes, that's why don't see many of them around.

But good effort! I attemtped a CAI but couldn't be bothered sourcing 3" pipe. It's harder than i thought and not worth the price people pay for custom IC piping.

Nesquik,

That video was awesome! Damn dude, a lot of editing and skills went into that, very cool. You know, just a thought since your filter is so close to the ground/tire, they make pre-filters that go over the cone filter. They use them a lot in off road racing. Doesn't hurt the flow at all, just protects it and helps it filter out more dirt/debris.

I really don't think the pipe he is using is PVC. I had to use that exact same stuff to make framework for my boat airlift. It's called something else, and it's used for plumbing applications. I will ask my roomie, he knows. I think it will hold up to heat better than PVC would.

Car sounds good man! Could you feel a seat of the pants difference?

They make these fabric/cloth type covers that slip over the air filter as a pre-filter.

They are knit or woven or whatever so fine and do not let water particles in, but allow air to flow regularly.

I tried finding a picture, but I couldn't remember where I saw them before.

An old trick I've heard of is covering the filter in pantyhose, but I can't say I know if it works or not.

Duly noted, I'll definitely keep an eye out.

On another note, I was at Home Depot this past weekend buying wood to fix my fence, and I overheard a group of guys in the plastic piping aisle saying, "Well... you're not really running that much boost, so I guess this would be ok..." When they saw me, they got really quiet all of a sudden.

Good luck to them

To CROYCE992:If you do end up getting a full CAI, you might want to consider adding some mesh behind the inlet in the front bumper, and if you want, maybe some panty hose as well to deflect debris. When I had the semi-CAI, I put some panty hose at the end of the flexy pipe that went to the front:

Thanks, man! It was about 6 hours of shooting and editing, I took a whole bunch of other videos as well for another upcoming video project

And I'll definitely look into a pre-filter in the near future.

The throttle definitely feels more responsive, and despite the hot engine bay, the pipe is always cool to the touch
