    Hey guys, I happen to have a spare ls3 intake lying around from a Camaro we supercharged and it occurs to me that it might do some good on my 2010 Silverado. I haven't found much on ls3 intakes on a 5.3 only read on ls1 intakes which people say is purely for looks.

    My question is: Is there any performance to be had with the LS3 intake and if so what needs to be changed to accommodate the install. I am currently running a stock truck with an airaid tube and k&n element in the factory box, just bought a diablo tuner, and plan to add some shorty headers soon.

    Ls3 intake is for ls3 heads, you would need a manifold with cathedral openings.

    Most people advise against shorty headers because they offer no benefits over stock manifolds. Go with a set of long tunes with the factory "cat back" and you will be much more pleased.

    car intakes suck on trucks below like 3500 rpms, shorty headers are a waste of money for the power they make, handheld tuners are inferior to custom tunes

    edit:
    Airaid tube is cool, K&N filters are garbage in my opinion, they do more damage than good, and screw having to maintain a filter

    What would be a better choice over the K&N?

    anything that doesn't have to be oiled, stock preferrably

    Disagree based on experience in multiple applications. Particularly in motorcycles where sensitivity to air flow is much more pronounced. I've run every filter combination imaginable in V-twins, inline 4s, 2 strokes, and K&N is hands down the most reliable and durable. I can pull the filter, wash it, air dry, spray it lightly with oil, and not think about it for 25k. Can't do that with a disposable filter. Even in my truck- it's not like you are oiling it every time you open the hood. It's a light coating with aerosol and done. On a passenger car like my wife's Prius I literally put it in and check it once a year if that. I'd rather make a one time purchase that requires little to no maintenance than fork over $20 for a Purolator every 15k. Unless you are soaking it down with oil it's not going to harm the engine. I get that people think it's more work but like I've been running K&Ns forever with no issues and very little fuss and it's not a performance/horsepower thing (Prius!)- it's a maintenance interval deal.

    cool.

    I've seen k&n's take out probably 100 mass air flow sensors in my career, people don't know how to maintain them, and I consider the kind of person that comes on to a forum to ask what kind of air filter they should run to be lumped into that group of people that won't be able to figure out how to maintain a k&n

    True. And good point. Kind of like one person destroying their truck with the same lift as anothe guy...the common sense factor.

    I barely spray mine. One of my bikes will backfire if the filter is dry but with a light mist on it she runs great. The first time I used a K&N I thought they were garbage but I've grown to like them.

    Offroad applications I would never run a k&n. They are a "high flow" filter which means they are not filtering. Foam filters in offroad apps. K&n is old tech. The same can be done with dry filters.
