whats the difference between a funnel ram air intake (fierostore.com) and a cold air intake? ive heard something about funnel is for hot air. And the only difference ive seen is the funnel ram is shorter. Anyone know the performance difference or any differences?

First, the Fiero's air intake is already better than it needs to be. Your engine won't suddenly gain 15 HP with a new air intake.

Second, a cold air intake replaces the hose from the stock vent with a shiney pipe. If it's the kind that ends in a cone filter inside the engine bay, it's actually a HOT air intake and will DECREASE engine performance.

Second and a half, K&N air filters provide only a tiny bit more air flow than stock ones, by allowing far more dirt, dust and other engine ruining things to get past. Not what you want

Third, I have no idea what the fiero store's kit is. The picture makes it look like it eather replaces all the original intake, providing you with a piece of junk hot air intake with a K&N filter, or it joins up with the stock air filter box (unlikely) and gives you a nice shiney pipe and the above mentioned piece of junk K&N filter. Eather one would do nothing for engine performance at best, or decrease it significantly at worst.

The only thing nice I can say about any of these intakes is that it changes the engine noise. The engine noise becomes louder and more windy, in a way some people like.

So if you like your Fiero to be fast and have a long life, stick with stock. If you find yourself looking at honda civics and thinking "I wish my car were more like that," get which ever air intake you want.

get a 91 or 92 crx intake off ebay and a good filter... got my pipe for 35 shipped then bought a good filter. It places the filter outside of the engine bay, right behind the little air scoop on the side of the car.

ya ya - the right answer
the stock cold air intake is pretty dang good tho. the CRX one adds some heat shielding, and removes many of the bends.

You can also build one of these cai`s http://www.westcoastfiero.com/intake/intake.html from parts that can be had at a Lowes, Home depot , ect and save a pile of money..

the CRX one is already pretty dang cheap

I spent $10 on a air cleaner flex hose to go from the air filter housing to the fender vent.

$Rich$ posted one of those 1/2 down the page, this one ended up in the trunk. Fender 1/4 panel vent would probally be the best place for it....

in order to do that one, wouldnt it cut thru the wheel well?

edit: i just looked up ebays crx intake, and the cut off is actually either 88-91 or 92+ (looks like two different intakes).....so which is it the 91 or 92?

The Fiero's stock cold air intake is more than adequate for the task. It's been dyno tested and found to offer no significant restriction. There is NOTHING to be gained by replacing or modifying the stock air intake system.

Except style - replacing the rubber air tubing from the plenum to the air box with a chrome pipe won't hurt anything and it'd be shinier.

But as far as performance goes, no matter what you do the best you can hope for is to not make it any worse. There isn't any improvement possible - it already flows more air than the engine needs.

Remember, it's a Fiero, not a Honda. Fieros came with a cold air intake from the factory...

If you look on the drivers side, a foot or so under the srut tower, where the insaltion just about stops, you`ll see a hole allready cut in there, that is enough to house just about anything you would want to install , so no reason to cut, this would land the right cai tube/assembly just about where your fresh air hole scoop is inside the drivers side 1/4 panel (hidden), in my case with the 3800SC I dropped mine threw there, then way down towards the ground to pick up colder air.. Down side of that is you have to pull the inner wheel well insert out to change the air filter.

not true.
the Herb Adams test showed the stock Fiero Cold Air Intake is as good as a open Hot Air Intake - as in - fresh off the y-pipe hot air intake.
yes, the stcok Fiero cold air intake system is good. but a stright pipe, cone filter & smooth metal pipe is better than a 180* bend in the water seperator, pair of 90* bends to the air filter, then a 90* bend in the air filter, then a 135* bend in a corrugated hot rubber tube.

Please post your source for the above statement.

it would be 88-91. There is no 1992 crx...91 was the last year.

That is only true if you don't clean and oil your filter properly (and regularly).

From your link:



Lower is better, meaning less restriction. The K&N had the lowest restriction of any of them, although it did pass the most dirt. Big surprise, the cleanest filters have the most restriction, whodathunkit.

The difference though would probably ammount to less than 1 HP on an engine with as much filter area as the Fiero. The bigger the filter, the less restriction matters. So with that in mind, I'd rather a filter which holds back way more dirt, at a cost of a fraction of a horsepower. Changing your spark plug wires or your old sensors would probably give a bigger power increase.

Just do or get Rodneys' mod for the airbox, the stock tube and airbox design are fine, it's just the intake manifold that stinks.

I never said they were worthwhile for a performance gain in $$/hp, that's up to the individual to decide. I'd put more money on the K&N making a slight difference than I would underdrive pulleys. They are nice in that they are a cleanable filter, if you don't mind cleaning them and know how to properly oil them. You wrote "Second and a half, K&N air filters provide only a tiny bit more air flow than stock ones, by allowing far more dirt, dust and other engine ruining things to get past. Not what you want" The first part of your claim is not true. They have 1/2 the restriction of a Delco and unless you operate in extremely dusty conditions, the amount of dirt passed is minimal at best.

Your comment that changing the plug wires or sensors would "probably" give more power may or may not be accurate. For all you know, the sensors are all functioning properly and the car is in fresh tune with a solid ignition system.

I didn't say that a K&N would provide a tiny bit less restriction, but rather only a tiny bit more air flow. Again, due to the size of the filter. The existing filter is large enough to give the stock engine all the air it can use.

As for not knowing what state the sensors are in, that's why I said probably. Most Fiero owners don't replace all their sensors every so many miles, but rather wait until one begins to operate poorly enough to cause very obvious running problems. There's a lot of room for performance loss between when a sensor is new and when it's very seriously inacurate.
