MAF Mystery - Part 1 of 4 - Intro & Test Results

[ghrialto]

@pepelepew debo aceptar que estaba equivocado en cuanto al consumo de combustible con respecto a la entrada de aire. Pero sostengo el resto de mis aseveraciones.

[ghrialto]

Este tipo de filtro contamina con aceite el maf sensor sin importar lo que el fabricante del filtro diga para defender su invento. Otro punto es que no ayuda a reducir el consumo de gasolina. A mas aire entrando en el motor mayor gasto del combustible. Supuestamente el fitro dura 1 millon de millas. Pero el consumidor decide si cambia, regularmente, filtros de aire barato u cambia maf sensors regularmente.

@ghrialto vale mia sin forma de que te molestes pero estas mal entre mas aire puro le entre al motor preferiblemente aire puro menos gasolina gasta no es una differncia muy alta pero se sinete en el bolsillo no que porque si tanueas el carro y te dura la semana completa con el K&N puede que te duro un dia mas si es caso pero entre mas aire reciva el motro menos se esfuersa el mismo para que los pistones reciban aire

[PePeLePeW42089]

@PePeLePeW42089 un motor turbocharged gasta menos gasolina que una supercharghed con la diffrencia que el turbo funciona libremente con el exhaust maniflod mientras el supercharger fuciona con la polea de el ciguenal que para ponerlo a fucnionar el mismo SC se come de 50 a 75 caballos de fuerza hacerte gasta mas gasolina que la necesaria vivo en canada e tuneado y e preparado carros para track media milla una milla quarto de milla drift y creeme que es asi

[PePeLePeW42089]

@PePeLePeW42089 que mucha gente note la differencia depornto es asta porque no saben mucho de carros adios :)

A more free flowing air intake/filter reduces the work the engine has to do to suck the air in to the cylinders, therefore the engine can use this power to drive the car instead. That's what this type of filter is about, not about adding more air...

Learn about engines before you post rubbish.

kn are good but all big manufacturers uses mann

[Blunder1248]

You find on some of the manufactures standard air filter have oil in them!

[TwiztidxxNinja]

If K&N is such a great filter why doesn't the manufacture put it in from the beginning? I would have to say that the engineers that design the cars know more about airflow than a company that make a filter. Car manufactures aren't all about horsepower they are about the longevity of the vehicle. Has anyone else clued into the fact that with more airflow that means more fuel has to be added and that lowers the fuel economy?

[Blunder1248]

Its more about induction noise. Manufactures dont want their cars sounding like a race car.

Also they make loads of money from using their own service parts.

On the tuning side of things more efficiency means less power needed to move the car.

Turbos were designed to save on fuel.

[TwiztidxxNinja]

Are you talking about the filter or "cold" air intake? But how can more air flow make it more efficient? The computer will see more air and add fuel to keep it at a ratio of 14.7:1, if it didn't your car would overheat the engine causing major damage. So what did you gain? If more fuel then how do you save on gas?

A turbo forces air in, so literally putting 10% more charge would create 10% more output, just for a number. Of course the're efficient, they use exhaust wasted to force more air in.

[Blunder1248]

On a standard setup the ecu will restrict the power if too much air is going in. If you remap the system then you can take advantage of the mod. if the engine creats more power then in thorey you don't have to hold down the peddle down as much to go 30mph! unless you like the engine noise & put your foot down lol

[TwiztidxxNinja]

You just shot yourself in the foot. To gain power you have to mod the PCM... for an air filter your moding the PCM... if you just mod it without the air filter you will get more power. I thought we were talking about air filters and power not PCM reprogramming?

Vehicles now run on 'fly by wire' systems so the actual amount you push on the the throttle is not the amount the throttle plate moves. The PCM controls that too.

So, how does an air filter create power again? Right it doesn't.

[hellzone100]

thats why i drive my 88 Conquest TSI :)

OLD SCHOOL!!! and good on MPG!

[lovemym16]

one simple reason money

[Flanker84]

Maybe you're right in the part about the engineers from the car manufacturers but will you buy a spare part every 4 or 5 moths (air filter) instead of buying just one time a K&N filter that you will change in 1'000,000 milles?

Spare Air filter = $15 US dollars

K&N Air Filter = $45 US dollars

I bought a K&N air filter for my car and it works great, my fuel economy was improved (a little but it works) and my engine sounds better and works like silk, soft and smooth.

[2009jimmy2009]

plus it would be too expesive for the manufaturer to use these, thats why they dont use copper brake pipes etc. . . . .

[KNfilters]

@TwiztidxxNinja Manufacturers don’t want to use lifetime products in any vehicle because they can’t make money on non-replaceable items. You are correct with your statement of more air needs more fuel, but an intake system or high flow filter does not add more air to your engine (only forced induction, i.e. turbo or supercharger, can do this); induction systems eliminate restriction allowing the engine to pull air in easier.

[TwiztidxxNinja]

@KNfilters Honestly? So you're telling me that OEM doesn't have reusable filters? How can K&N claim that their R&D is more substantial than a car manufactures? Toyota is putting down $1Million a day for R&D, how much is K&N? By adding just a cleanable air filter how much more can you gain. I have personally thrown on intakes and seen them lower the HP output of a vehicle. How will a little air filter do anything? Maybe the slogan should be buy this so you wont buy a $10 filter.

[KNfilters]

@TwiztidxxNinja I didn’t say manufacturers don’t have reusable filters in their cars from the factory; Ford equips a lifetime air filter in the Focus, which is why we don’t make a replacement filter for it. But what small percentage of vehicles comes this way from the factory? At K&N, we develop air filters and intake systems, which is a small part of a vehicle; a car manufacturer has to develop a vehicle from the ground up. R&D is expected to have a dramatic difference in cost.

[KNfilters]

@TwiztidxxNinja . Allowing air to be drawn into the engine easier will give a HP increase because the engine doesn’t need to waste this energy and can transfer it through the powertrain. K&N’s air filters are unique because the cotton gauze media used allows more air flow without sacrificing filtration; on bonus, cotton gauze is cleanable and reusable

Reading the comments, clearly TwiztidxxNinga is a BRAINLESS RETARD.

[KNfilters]

@TwiztidxxNinja If you look into aftermarket items, you will notice many car manufactures produce an aftermarket intake system that they say adds power, i.e. TRD, MOPAR, GM Performance, etc. I am happy to help you with your personal concern of a loss in power you have experienced; I will need you to have your dyno tests and contact me at 800-858-3333.

[3rdSuspension]

@TwiztidxxNinja - You actually believe that Toyota drops 1 Million per day in testing???

[WWBZT1]

@KNfilters YUP It's like a company that made lightbulbs that did not burn out, which they can make. If they did there would be no repeat customers.

[3rdSuspension]

@TwiztidxxNinja - such a freaking easy answer "COST CONTROL" why else? You have such elementary and unintelligent comments. Not even worth the explanation.

[nukiwimet]

K&N the only way to go

[billayles]

K&n's don't come standard on vw's not old ones, or new ones as of yet.

But the old vane flap flow meters were more reliable than the newer mass meters.

[losipoop]

there are different kinds of sensors why only explain 1 type... i bought a cheap k-n-n copy and no oil...i'll change it later for 20 bucks. i have a temp. and flap type. also... i think i seen a stock JETTA GT '98 with a k-n-n. from the factory. the volkswagen factory. originally. with no modifications. i actually have the ram air box plate thing on my '89 jetta. no matter what k-n-n is a classic and should be the first perfomance upgrade to any car.

[billayles]

There is always new things to be found because thats how science is, and because of this they have more knowledge to make better filters and intake systems.

I find it rather strange why manufacturers make high bhp cars only to fit restrictively small intake pipes and air boxes which only decrease bhp, and k&n comes alone and is basicly re designing the intake and filters with double digit bhp gains just by swaping over a few parts, it makes car manufacturers look asshamed?

[tainted111]

I have K&N and if anything goes wrong with the MAF. i'm going to change out the air filter. Give them less reason to blame something else and to find the real problem

[afehrenbach]

Thanks for posting this! I have been using k&n for years and have complete confidence in your product. I just bought one today for my Lexus.

[rudican]

gosh they studied the maf sensor and engine airflow for 35 years and still haven't got it figured out yet! And after its all said and done, have they increased the performance, or just made it unessesarilly complicated? Of cource parts are fucking expensive these days .

[exogenetics]

I hope every aftermarket part is being supported like that. KNN is simply the best....

[canoeshoe]

congratsssss K&N!!!
