Does a cone filter do anything?

Just for future reference, there is a popular theory that manufacturers make their cars/trucks to have less power..............how does that make sense to you???
They are in a competitive market
"Please buy our truck because it has less horse power than............."
Yup that makes for a good ad, right, lol.
Manufacturers do value MPG, because that SELLS vehicles
Manufacturers also have to meet emissions requirements for that model year.
Emission add-ons like Cats and EGR systems do NOT effect performance, that's a myth, EGR system increases performance by preventing pinging, Cats do not "block flow" unless they are damaged.
Manufacturers use cold air intakes with 200% air flow for air filters, so they have to get REALLY dirty to effect performance.
They use tuned exhausts for best mid-range power, you can change to low-range headers, but you lose the mid-range.
Adding the least amount of fuel for best MPG does effect performance, more fuel = more power, that is why a 302inch V8 has more power than a 140inch 4cyl, it can use more fuel, which is also why the MPG sucks on a V8 vs 4cyl, lol.
So unless your "upgrade" can add more fuel then it is purely decorative, which is fine, nothing wrong with "looking good"

Anecdotal stories from satisfied customers, and nothing wrong with that, it is window dressing and can sound better.
Problem is the empirical data from independent testers using dynos to test these types of add-ons can't get them to increase power.
The power increase is in the belief that it increases power, and belief moves mountains according to some, so who am I to argue with that.

Yup, that's why, and how, they sell them.

i guess while the threads going...what do you guys think about snorkels? do they have any advantages for my little 4 banger? my brother told me that they allow you to go deeper into the water without the air filter sucking up any water. with my 2wd i don't do hardly any water crossings except at my fishing spot...which is only like 3 feet deep lol. it seems like with the combo of the engine sucking in air and my truck driving would really get me some air in that little engine. but let me know what your experiences are with em

For water crossings you need to switch to an electric radiator fan that you can turn off manually, the belt driven fan will soak the engine bay and can even cause a stall from electrical issues.
That would be first.
Second would be vents on some transmissions and differentials that should be raised if high water will be encountered
Snorkels are very practical.
Ranger air intake is fairly low on rad support, but above the bottom of the doors.
So if you will be going thru water above the bottom of the door then a snorkel would be a good add on.
Engine has to work a little harder to pull the air in but a Hydrolock(water in a cylinder) will bend rods and break pistons so small downside to a snorkel if you need one.
