Is there a way to improve airflow to the engine for under $100 on a Gen 2 while maintaining a stock appearance ?

Driving the car headlong into a hurricane isn't an option ... it's not that time of the year.

The only solution I've found is replacing the stock air filter with one from K&N.

Most of the year the air is so hot, stepping on the accelerator provides the responsiveness of an LTD Crown Victoria. This is not what you want when you're trying to get on a busy highway.

I've read about:

1) Changing the air box so cooler air is directed from the front of the car and not the side

2) Changing to a conical type filter

3) Heat shielding the air intake

Would any of this make a significant change in performance or fuel economy ?

Would doing any of the above require an adjustment elsewhere ?

you can fab up some kind of conical filter and box and attach to stock tube to throttle body...but gains are basically unnoticed...also remove the air silencer at bottom of airbox that bolts in through inner fender...

I have only removed silencer...cars seems to perform well in all temps for me
 
Take out your inner fender well shield and remove the air silencer, and re-bolt in the filter box assembly. This will leave a nice big hole for air to go thru to your filter. It will also make it easier for you to replace your air ride compressor when the time comes. Reattach your inner fender. This will provide you with all the air you will need without sucking in warm engine bay air. Install a new stock filter and you are good to go. For looks you may want to cut off some of the intake tube appendages and reseal (glue) the openings shut.

x2. Somewhat easy and FREE!
 
I'd just Leave it, k&n will cost a bunch of money and drivability issues if over oiled, a cone filter will suck in hot engine resulting in a loss of hp and create nox. My car get 33 mpg and run mid 14s with the stock air intake assembly. So I ask you why?

The one I have been working on had that set up when I bought it. I returned it to stock minus he silencer and the resonator.
 
snorkel delete, aforementioned

That reminds me we need to get together so I can get that from you
Maybe have a listen to the da too.

todd2fst4u,

The more I think about this, more questions arise.

I read elsewhere that airflow is restricted by throttle plates which would explain why performance and fuel economy go unchanged.

Since the difference in performance from cooler to hotter air is quite noticeable, it would appear that increased oxygen density would improve performance more than breathability. Of course, ease of breathability is important.

If that's true, then finding a way to stop the air temperature from being increased by engine bay heat should help.

Is that why performance air intakes use insulation to block heat exchange ?

I've read recommendations that also talk about changing the direction of the air to come from the front of the car, not the side. Wouldn't water or debris be a problem in this design ? Or would the air inlet be behind something that offers protection from that ?

What about changing the air intake pipe to one that is insulated ? That might make a dyno change, but would you notice the difference ?

The only thing I can think of is changing the air intake tubing, opening up the air box and switching to a cone filter, but that isn't under $100. More like $300 plus.

Why don't you check out my post on this.

Given what I've read about the amount of work and widespread disappointment in performance and fuel economy when removing the air silencer, I'll just leave it on.

Taking the air silencer off would also cancel out the negligible benefits of the two layers of Dynamat EX installed under the carpet. I can't say Dynamat under the carpet significantly reduced road noise, but the upholstery shop who replaced the carpet, threw it in for free so no financial loss. You'd probably have to sound insulate the doors, roof, trunk and interior firewall as well to claim a significant noise reduction.

Perhaps heat insulating the air box and air intake tubing would provide a cost effective and noticeable driving gain.

Removing the snorkle is still your best bet

performance?

I removed mine on The Brown One just for a cool(-er) sound....but it helps performance also? I recently had the bumper cover off The White One but was pressed for time so did not pull the snorkel and compressor....

Just an FYI if removing the air silencer is a no go on your list for all those reasons please stop trying to do anything performance on your car and leave 100% stock.
 
start saving your pennies for a cobra intake!

otherwise, just stop. you won't make a noticeable gain.
and i doubt the air is in the intake tube long enough for any real heat transfer to occur. you just have to pull it from someplace cool. like the fender. like the factory air box does.
