I'm sure there would be little to no performance difference. I think that with the K&N you're just paying for the name. With that said, i don't think i would buy the cheaper one. Looks goofy to me. The K&N looks so much better.
 
all cosmetic.. just depends how good you want under the hood to look... I will say the one piece (unless someone starts making them) wont last forever..
 
You can buy the one piece aluminum tube from ASMI for around $170, a K&N filter for $40, a spectre 8145 MAF adapter for $15 and have the same setup they're selling for $225. And then you can buy a heatshield from me for $40 and have a true cold air intake for $265 total.
 
Am I the only one that thinks the factory airbox looks far better than any aftermarket ones.

The chrome tube just looks completely out of place.
 
I'd rather have the tube black. Maybe one of these days I will paint it.
 
I am going to wrap mine with header tape. It gets pretty hot and I want to insullate it somewhat.
 
Thanks guys...keep em coming....

I do agree painting black was in my mind.....so the cheaper one would be my first choice on that deal.
 
Could they used a dirtier engine bay to display their product in that second link? To me that just screams quality!lol

Thought the same.

Not that my bay is clean at the moment but I've wondered if the stock intake tube with the baffles removed would sound/function similar to these aftermarket ones.

its been done before with some success... Def worth doing if you ask me
 
I'd never use sewage pipe in my engine bay.
 
I was thinking if painting I would just use black hi temp paint....maybe even an enamel.

Of course a black powder coat would be really nice too.....nice flat black.
 
thats not a bad idea

i did that and it made no difference. With the amount of time the air actually spends in the intake tube it does not absorb much heat, especially when you are at WOT.

The best thing to do to keep the air cool is to suck it in from a cool area, such as outside of the engine bay. Something to consider as well is my intake is in the engine bay so temp difference would be minor.

All numbers are example numbers

if the air in the engine bay is 75 degrees ambient temperature, then the heat of the intake would be close if not cooler as only so much heat will transfer to the plastic (more to aluminum if you have that) but the aluminum can not reach a higher temp than the ambient temp, as there is no direct heat source to it.

so wrapping it may lower the temp 10 degrees internally but the air going in would be hotter than the pipe so cooling it would have minimal effect with the air not staying long enough to cool to the pipe temp other than the air at the most outward diameter of the inside of the tube.

Now if you pull cooler air from outside then have the pipe wrapped so it is cooler it would then potentially keep the air cooler than unwrapped.

Also considering the price of the header wrap, the gains would be moot.

I suggest just trying to get colder air to the intake than trying to keep it cold.

some interesting info, alluminum intake is bad for heat transfer... plastic will be better for intakes and it is cheaper to produce.

The effect of a material upon heat transfer rates is often expressed in terms of a number known as the heat transfer coefficient. Heat transfer coefficients are numerical values that are determined by experiment. The higher that the coefficient is for a particular material, the more rapidly that heat will be transferred through that material. Materials with relatively high heat transfer coefficients are referred to as thermal conductors. Materials with relatively low heat transfer coefficients are referred to as thermal insulators. The table below lists heat transfer coefficients (k) for a variety of materials, in units of W/m/°C.

i did that and it made no difference. With the amount of time the air actually spends in the intake tube it does not absorb much heat, especially when you are at WOT.


How do you know it made no difference? The IAT sensor is up at the front of the tube by the filter.
I don't think it would make /much/ difference, and I would expect to have a highly customized tune to make any use of said difference.

Technically I do not have a measured difference, however, there was no noticeable difference.

but if you look at heat transfer properties of air, and the time it is in the tube, i highly doubt the temp difference. would do much to the measurable density of the air mean no performance gain worth the cost of the materials involved.

I will do some research and tests this weekend and post measured results.

i just thought a good idea aesthetcally is what i meant

I also agree that these intakes (while I assume flowing better than stock tube) would function better if routed down toward the front grill like the stock location - i had an old dart that I used Dryer Duct and an old cadillac air hat to run dual intake tubes from the carb to up under the grill on either side of the radiator - worked real well -

i like the looks but just not sure why these aftermarket setups stop short of the radiator.......
 
it certainly would not harm the performance but the cost would not justify the gains.

Also something to think about would be if you have the intake in the engine bay you will be pulling hot air and while driving you have cool air coursing over the intake tube, once insulated it works to keep the hot air in as well...

But in the situation where the air is cold then, yes there would be minimal benefit.
 
When I had my 96ish Cougar V6 I slapped on an aluminum cold air intake.....I had to actually put the tube through the area the old air box was and remove the splash guard to install the filter.

Added that I put on dual Magnaflow exhaust and that nice IRS that poor car never knew what hit it......just like the full size Chevy truck one night!
