Well, we all now how our engines HATE hot temps under the hood, especially with those cone intakes. So, here is a quick solution to keep the heat away that'll only cost ya $5. And it works pretty well on our 4th gens.

*sorry for the grainy pics, but my camera phone is weak!*

Buy one of these at your local Lowes or Home Depot. I think they are called flashings, but you can find them in the plumbing section. They are used at the base of chimmneys. Buy the 4-5 inch one:

Next, cut it in a shape that will fit behind your filter. You'll have to do some measurements to make it flush with the hood when down and over the wires, but the end result should look like this below:

When all is well and it's cut, just plop that little guy behind your filter: you'll be amazed how well it fits...see below. The rubber centern actually allows for some free play.

I went ahead and put scrap pieces from another one I messed up on and joined them together with small hinges to seal off as much of the right side of the engine bay as possible.

Now, if you cut it right, the hood will come down and be flush with the top of the partition, thus shielding you from all that hot air! Again, sorry about the bad pics...please enjoy and let me know if you should have any questions!

Very Nice. Have you noticed any difference in throttle response, power, etc.?

It *seems* like some low end has been restored and it's a bit more responsive in stop and go traffic. I'll really know for sure when it warms up a bit more....that's when my car used to lug the most. So far, it's been quite pleasing.

 

Very creative!

 

Good job!

 

i like the look and function of it. i think ill stop by home depot and try to fix one up as well. if i get a chance, ill unplug the temp sensor and ziptie it to the filter and monitor the temp with obd2 on my laptop and see if it helps any compared to nothing being there.

 

Cool! Pretty much like I did here V V V

minus the labtop.

Thanks for all the compliments!

 

good deal. i cant believe with how much i searched on the subject that i never came across that thread before but at least now i have something to compare mine to.

 

sweet deal........

will have to remember.
Maybe I will take some cheap sheetmetal or some flexible heat shielding to the engine side of the plastic piece. That should get it about another 7 to 10 degrees lower.

 

Yeah, that would be a good idea. But I think metal would actually absorb heat and that could defeat the purpose.

I've been driing around the past few days and I'm starting to feel the diference....especailly when idling for a few minutes and then taking off. I'll see if I can hook up my thermometer once again!

 

should we line the other side (facing engine) w/ aluminum foil to reflect the heat back?

 

look like a nice design, might have to try this...

get some #'s

 

I would assume that foil absorbs and retains heat as well. Some sort of heat & flame resistant material would be ideal.

Oh, and hooking some sort of hose to bring cool air in the new sectioned off part like - http://forums.maxima.org/showthread.php?threadid=102082
would be nice.

 

I would like to add that for a more *airtight* fitting, someone might try taking some hose, slit the middle, and run over the top to match the hood. I'll be trying this roof plate soon. Peace_

 

Sweet idea....i'm on it.
