Default New Intake - Air Box Question

Here is a picture of my new intake...

I have used a 3.5" coupler and a tube with a K&N filter. I drilled a hole in the end of the filter for the IAT sensor...It seems to be working well.

How do I make a better air box? I am using a roofing duct after the filter, which keeps the air pretty cool compared to around the pipe...I could use poly, or plastic, but where do I get it, and what are good types to use. Thank you for the input...

Actually, I like the roof pipe boot idea!

It just about completely shields the filter from the heat of the rest of the engine bay and that plastic is designed to take a good bit of heat without breaking down.

With that in place, I'd almost be tempted to use the plastic from another pipe boot and rivet/plastic wked it to that one to complete the closing at the front by the head lamp. Then use some auto weatherstripping to create a gasket to seal against the hood.

Hey, you asked for opinions and I'm one to brainstorm when provided with a decent idea...

IMO, that plastic is better than the hard plexiglas style stuff many have been forced to use. It is flexible enough to avoid the cracking/crazing some experience. Plus the black matches the rest of the interior bay trim.

When I put my hand on the filter, or near the filter on the protected side it is fairly cool. (It was 102 in Denver yesterday and 92 today). When I put my hand on the pipe, it is very hot. I have the sensor in the filter, which keeps it cool too. I wish I had a heat gun to see the difference. I think by dumb luck that I have the hood working with this system to keep the heat out. I will try a top cover, but I am not sure how much it will benefit.

I have seen a lot of the plexi covers, and I know that they do retain and collect heat. This little piece of rubber does not get that hot.

There is also a gap above the headlight that flows directly to the filter under the hood and over the light. I wonder if by putting a top cover on will limit that flow...

Thanks for the input...

Now to get my 180 thermostat, colder plugs, and exhaust worked on...

It'* hard to tell from the pic, but I did the same thing a few years ago. You have the right idea, now just try to finish the box around the corners. I was able to score the ends and bend them to form a box. I never finished mine but I had it so I could slip a piece of Lexan or Plexi in the top and it would fit in the joint I made for it.

The roof flashing is a good place to start as the 3" pipe slips right through the hole, which is flexible and rubber-like, and it'* a nice tight fit to completely shield it from the engine bay. Keep going

Yeah, I may have been misunderstood there. I'm not suggesting that you put a top on it, only that you put a seal around the top edge so that your hood seals down onto it. Also, do some searching here on "CAI" to see what people have done to wrap their intake pipe to keep it from heat soaking that intake air.

Many wrap theirs in Reflectix or similar....some have purchased special laced heat wraps that are proven to keep out heat soak.

I used 1/4 Lexan. I wrapped 2 layers of Reflex on the outside and used sill plate foam foam the inside.
