Had a spectra CAI on my 6.0 vortec for 9 years. I switched back to my stock box just to see if I could tell a difference in power. I absolutely lost power. It’s the high rpm high load power where you can feel it. I tow a 38’ camper and instantly felt a power loss during acceleration. Kept stock box on for a week then switched back to CAI. Stock box will never be used again.

What the guy said is right you basically losed power because you returned the stock filter not the air box, if you kept the air box with K&N filter you will gain more power because you combine race filter along with air box Becuse air box is sucking air from outside the engine bay But CAI it suckes from inside engine bay So you will be sucking hot air
@AllDayBlazer893 ай бұрын
@farisaltorki to be fair when the cars moving the cold air intake is superior then a standard bixix trapping heat inside it. When stationary, the standard air box is slightly more efficient. When moving the cai makes considerable more power as more air flow with coller air temp means higher density of air to fuel ratio which makes power load of like in winter how turbo cars go alot better...

@bassw1758 Жыл бұрын
I've always seen a increase in power when the filter had access to free-flowing air. You get an increase in power because the stock airbox is extremely inefficient, they're designed to be as quiet as possible, most of them have a hole right before the airbox sucking in air from your hot engine bay anyway, they do that so the engine doesn't hydrolock if you drive through a big puddle. If you fabricated an intake nicely you'll get five to ten per-cent increase in power, if the filter is in the middle of the engine bay sucking up hot-air you'll get a little bit of a decrease.

its more about the sound it gives you while making sure you dont lose performance. Its not about gaining perf at all atleast for me. I made sure it has fresh air supply with additional piping coming from foglight area on top of the stock "air" duct that the kit i have uses as well. from stop the car feels better and quicker, noticeably. Anything above 30-40 miles feels the same so there definitely is improvement and no real drawback of doing it. If you are in alot of stop and go traffic and its summer. There is a high chance of giving it a negative performance, then again. The stock airbox felt like that anyway. I always noticed the perf drop on my N/A engine with the stock airbox and 85F+ outside temps. it wasnt as snappy in lower speeds

While in some situations, this might be the case, that is not the case in every situation. There have been documented increases in power with aftermarket intakes. As far as the "cold air" part of the intakes, some vehicle manufacturers have taken this to heart. I had a 92 Chevy pickup, N/A with the filter on top of the carb, but the intake from that was fed from a port in the passenger side of the engine compartment that lead to cooler air from under the front quarter panel instead the hotter air from inside the engine bay, from the factory. My newer (than 92) Silverado does the same thing, as does my new Ram. So, while not strictly speaking an "aftermarket" intake, from my understanding, this lends credence to the belief that cold air intakes have something behind the science. If not, why do all three of these trucks (and others made the same way *from the factory*) try to use colder air from outside of the engine bay instead of inside? Pretty sure a lot of other vehicles do the same thing already, without aftermarket mods.

If you are going to say that the issue you have is with the name, that's fine. But to say that the dyno tests are "rigged" because they have the hood open? That is why they take a baseline WITH THE HOOD OPEN first. Everything else stays the same, or do you think that all dyno tests are only valid if they have the hood closed on both ends of the test? Does that accurately 100% reflect real world driving conditions? Not at all, that was not the claim, only that they increased horsepower. If the test after shows an increase in horsepower and on both tests, the hood is open, how is that "rigged"?
