So if you own a '14 to '15 5.3-liter powered Silverado or Sierra and you're hunting for the hands down, most affordable cold air Intake, but you still want to make some good gains on your truck with no tune required, then you should be checking out the Spectre Performance Cold Air Intake that we've got on my truck right now.At around $150 price point, this thing beats out most other intakes currently available, but I'm happy to say you will actually pick up some pretty good curve gains with this intake. If you're curious, take a look at our dyno graphs. We went ahead and we ran our truck on the dyno bone stock and it made 277 horsepower and 290-pound-feet of torque. We then installed the Spectre intake, we did not tune our truck and nor did we install any other supporting mods whatsoever, and we ended up making 277 horsepower and 295-pound-feet of torque.Now, I know what you're thinking. That makes for no peak horsepower gains and it only makes for a peak gain of 5-pound-feet of torque. But take a second look at that graph real quick and you'll see some pretty impressive curve gains. At pretty low on the RPM bend, we're actually making gains of 28 horsepower and up to 44-pound-feet of torque. I can't say it any simpler guys, that that is really impressive for an open element design intake that's this affordable and it does not require a tune. Pretty much speaks for itself. I don't think I need to say much more.Now, besides the fact that you get some really good improvements in terms of horsepower and torque, I actually liked the look of this intake because it's a pretty cool old school look, in my opinion. You've got this nice polished intake tube here, made out of aluminum, gives it, kind of, a street rod look and you got that cool open element design with the conical high flow filter.And lastly, you got a really nice powder coated heat shield here. So, overall it also cleans up under hood appearance in the engine bay. We're ditching that really ugly factory intake and air too.Other thing that's nice about the Spectre intake is it installs very easily. You can get this installed with a couple of basic hand tools including some screwdrivers and some sockets. And for that reason, I'm going to recommend this as a good first mod and I'm also going to give this a very simple one out of three wrenches on my patented difficult meter. Even if you've never turned wrenches before, you should be able to get the job done in less than an hour.So, again, if you're looking for the most affordable cold air intake for a Silverado or Sierra and you want to make some good horsepower gains, stick around. I'm going to show you guys what tools you need and then I'll walk you through the entire install step by step.To install your intake, you're going to need a standard drive ratchet as well as an 8 and 10-millimeter socket. And lastly, we're gonna need a flat-head screwdriver as well as a Phillips-head screwdriver, and a T15 Torx bit. An optional, but helpful tool includes a long extension.All right, so obviously we have to remove our factory intake tube before we throw our new tube on, right? And that's pretty straightforward. There's two band clamps holding the intake tube in place, one onthe factory air box and one on the frontal body. All you gonna need is an 8-millimeter socket and your ratchet. It's also helpful to have an extension because those clamps are, kind of, tucked down in there. All right, now, before you pull the factory air tube assembly out of the vehicle, you want to make sure you disconnect both of the breather hoses. That's for your crankcase and blow by. There's a little depression you can press underneath here and you can unclip them. All right, once you've pulled the air tube out, you can actually remove these breather hoses entirely. We're not reusing them. The kit does come with new hoses. All right, so we got our intake tube removed. The last step of our install is removing our factory air box but before you do that, make sure you unplug your MAP sensor here, [inaudible 00:03:24] pull up on this red tab here, squeeze underneath, and you can pop it out like so.This is just held on with a couple of rubber grommets so you can also just pop it out gently. So, with our factory air box and tube removed, we got a nice little comparison here against that and our new Spectre intake. And you can see we're pretty much ditching everything about the factory system in terms of function and looks, right?We'll get rid of that plastic. We'll get rid of this ugly resonator box/breather tube box here. We're going in favor with this nice, polished intake tube. Again, it is made out of aluminum. It's not plastic. And we've got that pretty old school looking cone filter with a very traditional black powder coated heat shield. Overall, it's going to make the engine bay look a lot nicer and it's going to clean everything up.Now, before we get rid of the factory air box we do have to swap over our MAP sensor to our new intake tube. They do provide you with new hardware to secure the MAP sensor. However, you are going to need a T15 Torx head screw in order to get these screws for the factory MAP sensor out of the air box.Now in order to install the MAP sensor onto your new intake tube, you are going to need a Phillips-head screwdriver for the provided screws. All right, now that we've installed our MAP sensor on our new intake tube, you can discard your factory air box and intake tube. You're not going to need them anymore.Next, we're going to assemble our heat shield. And in order to get this guy together, you're going to grab these small, little bolts in the kit and you're going to need the 5-millimeter Allen key provided in the kit. Now, to tighten all this stuff together, you're also going to be using the flat washers and the nyloc nuts. And in order to tighten those nuts down, you're going to need an 8-millimeter socket and ratchet.All right, with our heat shield assembled, we want to make sure that this filter is nice and insulated from all that engine bay air. So, we're going to install our weather stripping. Now, it is pre-cut for the heat shield. You want to start at this long tab right here. Put this and directly flush up against it.All right, now that we have the weather stripping installed, we got to do one more step before we install our heat shield, and that's installing the fitting for our new filter. You're going to press this on the inside of the heat shield like so, you're also going to grab the tube adapter on the other side with the appropriate size of band clamp and fit them together. Go ahead and tighten this down with your 8-millimeter socket.All right, now we're finally ready to install our heat shield. Now, this guy actually secures to the tray underneath where the factory air box was, and on that tray, there are a couple of 10-millimeter bolts. You're going to put those bolts through the little tabs on the new heat shield here. So you're gonna need a 10-millimeter socket and it's, kind of, recessed down far on the engine bay, so it's also helpful to have an extension for this one.Now, before we install our intake tube, we're actually going to throw our filter onto the fitting inside the heat shield. You can see it's a little bit of a squeeze in here. So while we have the tube off and we have a little bit of flex in the heat shield, we're going to squeeze a filter past this little bracket right here.You're going to throw the largest band clamp on top of the filter, and you're gonna need that same 8-millimeter socket to tighten it down. All right, next we're going to install a rubber coupler for our intake tube on the throttle body. Again, you're going to need the appropriate size clamp, and you're also gonna need your 8-millimeter socket to tighten down the clamp.All right, next we're going to install our intake tube. You want to make sure you have both remaining clamps on the rubber couplers. Go ahead and throw the tube in place, tighten the clamps down, and we're also going to install our MAP sensor connection.All right, next, we're going to install our breather hoses. Make sure you have the little clamps here on either end. You're also gonna need a flat-head screwdriver to tighten these down.All right, so once you've got your MAP plugged in and both tubes tightened down, that'll wrap up the install. And that also wraps up my review of this Spectre Performance Cold Air Intake fitting your '14 to '15 5.3-liter powered Silverado or Sierra. I'm Travis.

Optimal Upgrade. Few intake system upgrades offer as big of a leap forward as affordably as the Spectre Cold Air Intake. It's that quality boost in torque and horsepower you want while staying to a firm budget.
Precise Tuning. A handheld tuner can help you reach optimal throttle response. Use it before, during, and after installation for a pitch-perfect systemic calibration.
Secret to Success. The secret to the product rests in the mighty and formidable Spectre High Performance Racing (HPR) air filter. It's mounted on the passenger side, and really maximizes air flow to result in a powerful bump in performance.

Application. This Spectre Cold Air Intake with the polished finish is made to fit all 2014-2018 Chevrolet Silverado equipped with the 5.3L engine.
Like many of the other reviews, quality seems good and install was as instructed and not difficult at all. Issue with the medium size clamps are too large and you run out of teeth to get tight. Also, the air filter falls off. Going to try to rough up the mount and maybe file some grooves. This is a serious flaw. Seems fixable with better clamp or ridges on the mount.
I've had this intake on my Chevy truck (5.3) for 1 week and have gained 4.3 mpg. I set my cruise at 78 all the time and live in the hill country of central Texas. I went from 14.3 to 18.6 mpg. The installation was easy although I had to replace 3 of the smaller clamps because they ran out of tightening slits and wouldn't clamp any tighter. Also, after a couple of days I noticed my mpg going down; raised the hood and the air filter had slipped off. I took some sand paper and roughed up the hard plastic edge and it hasn't slipped off any more. So maybe I got it fixed. Overall, I'm satisfied with this product.

ScotInstallation Time: Less than 1 Hour
Nice improvement in response and sound
I'm on my 3rd one on 3rd different GM truck. Easy to install and maintain. Makes a nice improvement in throttle response and sound. Quite noticeable when towing a trailer. Hard to say on mpg, perhaps 0.5 mpg on 6.0 liter Denali I had. Currently on 2017 GMC Sierra with 5.3 liter and Borla exhaust. Significantly better sound than my neighbor with same set up and no cold air intake. I run cold air I take year round here in Michigan with no negative side effects.
Is the Spectre cold air intake smog legal in California?
This Spectre Cold Air Intake will not be CARB legal but Spectre is still working on covering their entire product line under recent California emission changes. For now, the product is certified in 49 states- not quite the full boat.

I purchased my 2012 Silverado LT towards the end of 2012. I previously had a 2004 Corvette that no longer fit my lifestyle hauling kids from sporting event to sporting event. I needed a vehicle which was more dual purpose, but I didn’t want a “work truck”.
