stock air filter vs. simota or K&N

[falken]

I have a 19 year old Lancer which I have kept for sentimental reasons. I installed a K&N filter on this Lancer a month after I bought it. It is a cone filter and is not one of the drop-in filters. It currently is still using the same K&N air filter up to today with no problems from the engine. I have only recharged this air filter four times in its lifetime and I do so every 20,000 kms as advised to me. (As advertised, these filters are supposed to be good for 50,000 miles before cleaning is required but that's for countries with less pollution than ours I guess). I remember being told back in the day that K&N filters work even better when they are dirty as the dirt acts as a filter for the filter. This car is running well and purring like a kitty.

I think the problem with oil getting into the MAF sensor is when you over oil your filter. I don't think the filter is supposed to be reddish in colour all the time but I usually hear of people cleaning their K&N filters as soon as it gets a little dirty.

I have a K & N cone filter too on my old car, I clean it every 50k kms.. I feel it's does work better when it's left to accumulate dirt.

Sir Chicks, minimal ang improvement sa increase of FC, pero matindi ang dinagdag sa HP gain ng makina. so bang for the buck talaga pala siya Sir.

Sa cone filter siguro pero sa drop in, I doubt kung malaki talaga.

Over-oiled will be obvious. Wet tignan. Dapat very light film talaga... then let it dry out a bit before using it.

Power increase will depend on the car and the filter. Some cars gain nothing with cones, which means drop-in lang talaga (about 1-3 hp only, though). Some cars like cones. Some cars will run like crap with a cone if you simply attach the cone to the stock MAF... and require you to add a tube.

Some cars, if you simply add a tube, you will lose power in some spots because the resonator chambers on the stock intake actually provide power.

Some cars either blow up (Subarus) or throw check-engine lights with the wrong intake (Mazdaspeed3 and 6, with the Mazda-branded CAI in the US).

My car makes 5 hp more with a long tube intake versus a short tube intake. And with the long tube, it makes as much power as a CAI, even without the cold air part.

tl:dr - if you want to make power with a filter, research, research, research to find the best option for your car.

You clean yours every 25000kms? Hehe ako dati kada 10k lang kasi nga masyadong marumi hangin sa atin. :bwahaha: Also because I have experienced a drop in my fuel economy and it went back to normal after I cleaned the filter. Now though, after 13k kms, my FC is still the same, kaya di ko pa nililinis ulit. As for the MAF issues, no problems at all after around 25k++ kms. and yes, just don't over oil the filter.

Edit:
Also do note that you're supposed to put oil on the "dirty" side of the filter ONLY. Yung inner part or yung papunta sa MAF/intake manifold ay di dapat lagyan ng oil.

Chicks, 25,000kms old yung filter ko. Had it since the car was 1,000kms old. I inspect it every 10,000kms and clean if necessary.

I wonder, would there be some real world benefit of slapping on an open type K&N short ram style on a 2.0L VVTi automatic Innova?

Depends also how restrictive the stock airbox is. If it's anything like the Corolla Altis 1.6L, there wasn't much difference with the short ram on my 2007 Altis for the daily drive (FC and performance wise).

Thanks! Gotta research for someone who's done it before first. Hehehe!

any other tsikoteer inputs?

so far, from other forum members experience, wala pa ako nababasa na nacontaminate maf sensor nila from k&n filters.
i think from those others who complain that their maf sensor is damaged, overoiling ang nagawa nila.

might be getting one. hehe.

When I added my cone system, the most noticeable difference for me was hearing the filter suck air. I felt a little more pep from the engine too but I don't think it was something to rave about. I am impressed though that the filter still works. In the long run, it saved me money plus adds a little more eye candy in the engine bay when you lift the bonnet.

K&N drop-in filter user here, 2.5L DiD non-VGT. No issue yet whatsoever. Just acceleration goodness.
Just make sure you buy the genuine. There are news circulating in the past that there are counterfeits.
Got mine from US. Even sold some in the *past*.
As for the MAF, you should maintain this part as well. Because even running on OEM filter, it will eventually fail or degrade that it will affect your FC and could even cause surging at some point.

Here're some info from K&N itself.
The first 3 URLs are MAF related. The last is all about the K&N filter in general.

Got this from speedlab last weekend



compared with the stock replacement paper air filter



Good better acceleration from a full stop. ayus for stop and go traffic,
and anything else i think parehas lang, kahit induction noise, tunog stock padin,
thou hindi ko pa binibirit, tipid ako sa gas eh. hehe. ill post updates pag nalabas ko
sa mahaba habang highway.

the fact na i dont have to press deeper sa accelerator sa rush hour traffic
masaya na ako. hehe..

Simota cone user here for my honda, ok naman din, no issues.
