I wanna do this for my next Mod:

Thanks heaps for this pic too (Not sure who??)

My engine Bay looks like this:


See I've got an External MSD Coil mounted under the Pod filter.With the Heat Shield there the coil will be contained in that area.
So my Question is..Is this going to be a problem in anyway? Maybe the air in there will get hot if the coil gets hot that is, I dunno?. Thanks Guys.

I wouldn't waste my time with that mod, but thats just me. To each his own.

It looks like an attempt at a pressurized box (which would gain power) .. to make an effective one would require better design/placement. The next best step is a cold air intake.

Yeah, because you haven't understood how intake air temperature affects on engine operation.

IMO this is the best way to do it, I would've done this too if my car had a ram pipe and pod filter.. Also Endyn, and many many successful tuners do it.
It combines the best of SRI and CAI, you get short, properly tuned ram pipe to get high power, and you can supply it with coldest possible air.
Trying to make it "airproof" and add some ram-air intake into front of car would be a great idea too.

I have put a tube from the front ducting air into that area.Is that what you mean by 'Ram-Air' (I have heard the term a bit but ???)
I looked in to making a fully enclosed box but decided against it cause to me it would seem like when your just Idleing it would get real hot in there.What I'm saying is that enclosed area would see big fluctuations in tempretures.Also when Idleing no air would get in there.

i wanted to do this but had the same worries...would enough air get in at idle?

when you say front ducting do you mean now you have in effect two air feeds cos that should help alot i would think! one to fog light hole and one to radiator duct? i would get one of those ram air but i like the look of having a nice fat filter actually in the engine not hidden away with just some pipe sat there instead, how would the heat affect a c/f heat shield? cos that would look nice

allthough it might look like it does something, you can look at it and tell that it'll still let hot air into the intake over the top between it and the hood and also all around over by the strut tower. you'll be lots better off with a real cold air set up that takes in air from outside the engine compartment! but they have their bad points too, like if you go through a deep puddle, you can suck in lots of water and hydrolock your engine! that's a problem for guys here in fl. where it can rain really hard all of the sudden and flood some streets really fast! :lol:
a friend of mine had a setup simular to the one in the pic, but it was completely isolated from the motor compartment. it was a metal box around the air filter, and it had a squishy gkst on the top that sealed it up against the hood, and it had a lil hood scoop on the hood that did the whole ram air thing with totally cool air from outside the engine compartment.
you see, just a shield wont really do much because hot air can still get past it! hot air kills HP!!!! so yeah, anytime you can get cool outside air into your intake, it's a plus !!! ;)

But aluminum dissipates heat from around the air intake????? not enough?

heck no! lol
remeber, the air under your hood is really hot, and it's moving really fast all around under your hood and it'll blow right past that lil shield, plus the intake tube is really pulling the air to it when you're gassing it really hard! ;)

haha thats my air box, and when combined with some cold air intake feeds (hence the pvc pipe just under the filter) when moving there is no way in hell that ull get any hot air into the filter.

it works bloody well and intake tempertaures stay constant unless sitting for extended peroids, but then once u start moving again they drop right own again.

im gonna be rebuilding the air box at some stage out of fiberglass and making it 1 piece

the cold air feed goes from where the filter is through the hole for the stock air box, turns forward then left through the bump in the bumper then splits into 2 and comes down into the front air dam, so essentually i have 2 3in pipes feeding into 1 3in pipe for a bit of ram air going on.

any questions dont hesitate to ask

heres a couple of pics of the airbox

and some of the cold air feeds

^^Thanks for the pics Jason.How did you do the join where 2 pipes feed into 1?(great idea too!)

heck no! lol

Thanks a lot,it sure does make a lotta sense to me.So it looks like a box is the go but I'm still concerned about the higher temps that will occour when Ideling and the large fluctuations in temps.Does anyone have any input on this? Is Hydrolock the only concern with a cold air intake?

Yes, I totally understand exactly what you are saying and your right. The reason I suggest not doing it is because from what I see in his sig, its for an automactic D-Series. Your better off saving that money on a setup that will net you bigger gains. You won't notice any difference in that kind of car.

I would just suggest a short ram air intake. Its the best way to go for an auto D IMO.
