        Cold air intakes work.......
        With a good exhaust of course.
        The most bang for your buck is still just "a tune" done by the right people. All cars come governed for fuel economy.

          I agree that cold air intake is useless, but replacing stock air filter with a high flow like K&N does help, especially on a turbo car. The minimal cost for the minimal gain makes it worth it. Same with catless exhaust, for the money, the gain is worth it on a turbo car, I have a BMW F32 and there are software apps that accepts the catless to not trigger a CEL. I think these power mods are a basic must on every enthusiasts' car.

            A cold air intake is not useless nor a waste of money depending if it's for your Honda civic yeah don't waste of your time and money but in my 860 HP inline 4 engine it's useful drawing in a higher volume of cooler air.

                                  except the fact that cold air intakes DO work if they are actually cold air intakes and not just a filter on a stick.

                                        Light flywheel and a 6 puck clutch makes a hellavu difference, some good coilovers, big tires and a upgraded brake system your good to go. Want more HP? Get a tuneable ecu. So like that every bolt on you put on it, you could actually tune the car for those parts. Also dont be one of those dumbasses that throw bolts on after bolt ons, no tune and when asked how much hp your car has, dont be a dumbass to say, “yeah i put a Cold air intake and uhhhhhhh their page said it would bring me 15hp plus the headers, its another 15 so yeah approximately 250hp NA.” Tf no, tune your car. Your car doesnt even know you installed those parts because of the set ecu, cars dont have a smart computer system, that says to itself, “hey loooky here, I can breathe more now, let me move faster.” 🤦🏽‍♂️

                                                  Cold air intake is more noise but NO acceleration improvement from 0mph.

                                                          The mod that I felt the most is swapping out my factory 3.55 gears for a 4.10 ratio, right behind that is the stainless long tube headers and cat delete, upgraded to 305/50/20 Toyo proxes and lowered the rear to level it out, all in all, I started with a 7.4 0-60 and now I'm running with 5.0 mustangs in a 2004 Dodge ram 2wd short bed hemi

                                                            I put a cold air intake on my 3.8L Chrysler minivan. It probably didn't add power, but going from the tiny 1.5 inch tube on the air filter box to the 4 inch intake tube on the filter made a bit of difference to the sounds (also no engine codes or any troubles, just slightly better fuel efficiency)

Also, going back from sh*tty low springs to original GT springs did help road holding, recalibrating the injectors to factory specs made it gulp far less gasoline, switching to ventilated disks instead of cheap single disks really helped with braking... The only mod I made that I'm not sure actually had any effect was mounting an intercooler. Well, it didn't really hurt either.

You really benefit from a cold air when you live in a cooler climate that doesn't see 100F temps outside etc. You will see a decent gain with a CAI on good days but most with open filter elements will suffer from heat soak in traffic (or staging at the race track). An open filter element is better in cool weather and definitely flows more air but a closed box will see better temps in hotter weather and have less of an issue with heat soak while making slightly less power in ideal conditions.

Sure just throwing on a KnA air filter won't make you notice any difference, but a good after market intake paired with a full head back exhaust will make be very noticeable.
