Air Intake question
 

I have a 1999 NBS silverado 1500. It has the 5.3 V8 in it. I'm looking to do a new air intake system. I was wondering if anyone had a suggestion for a semi cheap air intake but that still works well. What is your recommendation? Also how much will this help my MPG's?
Thanks so much for the help!

Any help please!

Hi Blazer Dude I've got a 2000 Sierra with a 5.3 and a AEM Brute Force intake system. Pretty happy with it but not really cheap. You can find an intake system for yours on ebay a lot cheaper and that probably works just as well. I saw a 1 maybe 2 mpg increase with mine. Not really that noticeable.

I've got the cheapo ebay cold air intake. Really they all do the same. I've read the most effective is an airaid mit and k&n drop in filter.

I used a specture cold air intake on my 99 with the 5.3 from summit racing and seen a 1-2 gain in mpg.

Volante CAI on my 4.8 2002 GMC Sierra ECSB & in tracking my mpg I saw in my very first tank a 2mpg gain despite all the "playing" I was doing enjoying the extra power. With the stock intake it wouldn't light the tires at all, not even from a standing start. It just went. Now it will light the tires with the brakes applied.

They are all about the same, and shouldn't make that much difference.

I designed the original air induction system for the GMT800 trucks (still in use) and the requirements were sized for the Diesel and MarkV engine airflows (1" Hg @ 272 g/s flow, from ambient air inlet to engine intake).

The 5.3 airflow was quite a bit less than that (hence the restriction is quite a bit less - like 1" Hg @ 253 g/s, if memory serves), so the production setup is more than adequate.
