K&N oil on MAF...is URBAN MYTH.

For those that care to know hear the other side of the coin.


MAF's get dirty from the finer dust that gets through EVERY AIR FILTER OUT THERE. It is just dust. The dust really has no impact on its operation. It the oily soot build up from the crankcase blowby that ends up on the Heater portion of the MAF that is the real problem. And this varies by engine and type of use.

K&N oil is too viscous and tacky when dry to end up on the MAF. Period. A myth. Many other reason are found for failed MAF's

Some don't like the Cold air Intake designs of K&N's. Possibly justifyably so. The round turbin design of these non-OE shaped air filters are known to interfere with the OE A/F calibration of a non modded setup on some vehicles.

But the K&N drop in air filters are proven. They are lifetime and save money.
The only reason I have been using them for 17 years. And never a MAF issue

I'm not advcocating K&N's for all, but merely telling those not considering them because of a MAF issue's that this is the wrong reason to not consider them.

I use CRC MAF spray Cleaner. Cheap enough from any auto parts store. Yes, yu CAN use Electrical Contact spray from Radio shack.
Which actually costs more money.

I saw one post that said they had an issue with a MAF and described using Brake Cleaner on his MAF. That's just crazy and irresponsible.

And, I'm sure that same member would blame a K&N filter for his failing MAF!!!

I'm sure there is some truth to this, but what if the k&n filter is over-oiled? I'm sure that some of that oil can build up on the MAF.

yeah, the truck has about 94k on it and I doubt it had ever been cleaned.

It's clean now though.

A great point that I failed to cover.

This scenario has been tested by K&N...yes I understand the caveats with this.

But, I have seen first hand an extremely over oiled K&N put into use on several occasions. There will be people who do this and never follow instructions...those who feel more is better. And the wash/reoil procedure is not required frequent enough to deveolpe a proper technique according to K&N's instructions. The service procedure is very Methodical, yes.

This is one reason I don't reccomend K&N's for everyone. It also allows for a false sense of security. Many people drop one in and never check them again for 50-60K miles.
They must be inspected every OCI in my opinion just like any other type of Air Filter. Fundamental stuff.

In any event, The air box collects the oil in the bottom due to gravity and I have never observed the Filter oil on any MAF at any time.
Sure, it would seem logical that it could, but every time I serviced someones MAF ,they were clean.

But it doesn't end up on the MAF.. It's viscosity is too thick and tacky when it sets up.
There's simply not enough intake air pressure to suck in this K&N oil in a naturally aspirated engine.

But, people who oil their K&N's should use the Spray can oil not the bottled oil.

Less chance of over oiling and with better coverage.
The overoiling just messes up the bottom of the air box. (no real consequence) But, yu know how gritty it gets in the bottom.
My spin.

Is the MAF sensor location right under the red arrow (see pic)? And it's on top of the air filter housing, right?

[LifeTech]

I don't see any red arrow! Or pix for that matter.

Check it now.

[Sigr6]

Yes, that is where it is. take out the 2 small screws and it comes right out.

The MAF is usually on the air intake system between filter and butterfly plate.

Now coming to increasing MPG, I would suggest doing the following..

1) Get new plugs (NGK only, all others come behind NGK in quality).
2) Change the fuel filter and get a injection service done.
3) Maintain PSI on front -- 8PSI more than recommended and on the rear 6 PSI over the recommeded number.
4) Clean throttle body and butterfly plate and change air filter.
5) If you already have 80K on ur O2 sensors, it is time to get them replaced (NGK Spark plug, NGK Spark Plug wire, NGK Platinum Spark plug for High Performance and Racing.).
6) Get the tires balanced and do an alignment.

That is what I can think of for now...
