I went to a web page that seems to have good deals on cold-air intake systems. It is called AutoAnything.com; and they have a system for my 2004 Silverado 1500 (2wd, 5.3L V8) that would apparently give me a few more horsepower and slightly better fuel economy. I am sure it would sound better too!!


Their price is $254.95, including "free" shipping. I suppose that if I got 2 more miles per gallon of gasoline, it might not take long to pay for itself. LOL! A cold-air intake system would be a great match for my Flowmaster exhaust system which was installed about a year and a half ago. My truck is also getting new spark plugs & wires this upcoming Wednesday.

Has anyone else here purchased this same system? How difficult was it to do? Did it take a long time? Have you noticed better performance or improved fuel economy? Is there a way to find it for even less money than the price on the aforementioned web site?

Thanks for any replies!!


2004 Chevy Silverado K&N FIPK Cold Air Intake - 2400+ Reviews on the K&N Fuel Injection Performance Kit - Videos & Installation Guides

 

the system is ok...only problem is it has just a heat shield instead of a closed box like volant or stock intake system. my vote is for volant or a drop in k&n filter on the stock air box with a airaid MIT tube for 125.00

 

I have airaid.
Volant with its heat shield is the way to go.
However what I am gonna do since I have an airaid with no heat shield
Is install a hood thathas a RAM air intake to supply the filter directly
With cold air.
I am gonna replace my L05 engine with an LS1 and theair intake is up front
I I will have to find a hood with theintake all the way up front or I will make a
Custom intake tube.

 

Why is the 'box' so important? Does that keep the temperature any lower than just a heat shield would?

 

Yes it does

 

You can't have "cold air" entering your chamber with a 250
Degree engine bay.
Exhaust wrap around the headers will help.

 

Then why do they call it a cold-air intake? That's kind of misleading, eh?

Even so, wouldn't the K&N 'conical' air filter still allow the engine to breathe much better than the stock box? Seems to me I'd still get better flow with it - which has to be good for at least a few horsepower or another mile per gallon of fuel.

P.S. I have a neighbor who is a former mechanic and will ask his advice if I can ever get ahold of him (different work schedules).

 

yes the bigger filter will allow better air flow, but when you're sucking in 200-250 degree temps from the engine bay you'll actually lose power when the stock box draws air from the fender and it's colder. the tube is the only problem on intakes these days

 

Wrap your stock tubes and air box with an insulating tape. Run a NAPA Gold (WIX) air filter, it filters well and flows better than stock.

The aftermarket flow better than stock because they filter less. Tons of info on this just use Google, Bing whatever and search. The NAPA gold flows almost as good and filters much better than the after market. Also I have seen some adapt the stock box to use the conical aftermarket.

Yes the term Cold-Air kit is misleading and a waste of money IMHO.

 

Well another thing is that the stock intakes may be restricting.
Like with a stock filter, you may get only like 1000 cfm but at 100%
Throttle the engine may require 1,200 and the cold air intakes have a Max of
Like 1,400 cfm.
(I was just throwing those numbers out there, IDK what anything is rated for)
So the cai may allow theemgone to breathe better.

And what I did is take a Cai flex tube and adapter and plugged it into my filter
Then ran the tube to supply the intake with a direct source of exterior air
