K&N FIPK and making the AFM dirty?

[supraman7mgte]

Could this happen? Would an oiled filter element get residual oil on the AFM wires and cause wrong readings and bad fuel economy?
Better question,would just running a DRY cone filter be better?

Not on the wiring, ours is not a hot wire MAF. But yes over oiling can make for bad signals.

Hence, the reason K&N says not to do it.

Over-oiling is bad, but not oiling it may be worse.
The purpose of the oil is to catch the smaller particles that have the potential to slip through the filter media. Without it, more small particles can and will make their way through.

then is there anyway to clean the inside of it for just in case reasons?

If you do...use an electronics/contact cleaner...do not touch the inside with anything! I've seen several of these sensors after they were cleaned with carb or brake cleaner...they all failed.

K&Ns do let more shit in.

speaking of intake systems

has anyone got a link to that page on filter comparisons?

C&R (brake cleaner, carb spray, etc) Just came out with a spray for cleaning MAF sensors, and will work on AFM too. $3.50 can. Pepboys, Carquest, Autozone, wherever they sell C&r stuff.

yeha it seems HKS gets a bad rep. im happy w/mine so w/e.

 

[suprra_girl]

thanks for the link

I don't know about that. The LED and phototransistor are completely different than a control wire with small amount of current in it. That electronic cleaner does work great with lean codes on a MAF. But I have never heard of Toyota saying go ahead and clean the Karman Vortex. Be careful.

When I switched to an AEM Dryflow Synthetic filter from the HKS SMF, I noticed that there was excessive buildup on the honeycomb, so I pulled out and set aside the electronics and blasted the afm housing with carb cleaner. Also noticed a few fins were slightly bent (maybe 0.5-1mm in at most) so I straightened them out with needle nose pliers.

Is it not a good idea to use this method for cleaning? I figured with the electronics out of the way, carb cleaner wouldn't be too bad...

What you did is fine...it's the electronics you don't want to use carb cleaner on.

Here's a great link to everything you wanted to know about Filters, Oil, and other car parts. I stick to Wix filters myself.

Do you use a Wix drop in or a cone? If cone, how is it and what adapter are you using?

I use all Stock replacement Wix filters. I won’t upgrade the Supra Air Cleaner due to reading at more than one site there was actually a loss on dyno pulls when aftermarket filters were used. It seemed the best intake was the stock one with stock type filters. There is a guy who did his own testing of what filters let thru by using a system of gauss material after all the major brands of filters, and K&N seems to let more small particles of dirt through by far than the stock type such as a Wix. His test can be seen at Bobtheoilguy's site. I would imagine the best way to increase any performance through an MKIII air box is to some way make it Ram Air, a pressurized box will certainly flow more air than one that has to suck.
