And they would all be wrong. I'd explain why but I can't be bothered.Basically the small reviews that i've found online. Some people said they gained power, some didn't, but they all said they gained MPG. As you know with these V8's, any extra MPG's we can get is worth it, to me. So was wondering if anybody had any real world results.
Sign me up for that !Agreed. As long as you understand the benefits are more dirt in your engine oil and a sticky intake tract. Sticker's cool though.
According to my very unscientific and unproven sources, the re-usable oiled air filters aren't as capable of removing impurities from the intake air. These fellows have seen more intake tracts that I ever will so I'm taking their word for it. They claim the OEM style paper air filters are superior in filtering the air vs the K&N style filters thus the intake tracts are cleaner.So why does the oil get dirtier with a K&N? Does it just let more dirt through vs a paper filter?
Bingo! Your engine draws in air through a cross-section of a couple of square inches on either side of the throttle body plate. The power output of your engine is controlled by varying that area. Even at WOT the cross-sectional area of the throttle body is only about seven square inches. Add to that the fact that the ECU uses data from the MAF sensor and from the O2 sensors to maintain a stoichiometric air/fuel ratio.I wonder if it's a matter or letting more air through the filter but also more contaminants vs cleaner air, but not as much. I suppose leaving the air filter off would also give you more, dirty air too So what's better then, more air with slightly more dirt or cleaner air, but less of it? I guess it's probably so minimal (the amount of air) it doesn't matter.
The ECU will trim the gas flow to compensate for the reduced air mass that comes from restricted airflow, but it cannot make up for the reduced flow. The ECU meters air and fuel, but it can't do it efficiently when either one is restricted. Performance will be reduced which will effect gas mileage.The ECU compensates for any flow restriction from a dirty air filter. In fact the air filter creates virtually no pressure drop, clean or dirty.
This is just silly. Not only are you restricting air flow, but those particles can eventually push their way through the filter media the longer they are there.And a dirty air filter is a better air filter than a clean air filter.
Almost everybody believes what you believe. And you're wrong. To be honest I don't care. I put the facts out there for the few people who have an open mind.The ECU will trim the gas flow to compensate for the reduced air mass that comes from restricted airflow, but it cannot make up for the reduced flow. The ECU meters air and fuel, but it can't do it efficiently when either one is restricted. Performance will be reduced which will effect gas mileage.
Thanks for signing up to make that comment. And yes, that's exactly what pewter05 was arguing, that with a dirty air filter the ECU won't be able to maintain a stoichiometric air fuel mixture.No one is arguing that the computer can't maintain a stoich mixture in adverse conditions. The fact remains that the driver would have to increase the throttle slightly to achieve the same HP/TQ output. Every vehicle will have different results but its simple physics. The engine is a glorified air pump plain and simple.
