Hi Everyone.

I've been looking online for ages for a good high flow air filter.
Mates say don't go with the K&N as they use oil in their filter, but can't find any other good options.

Foam vs cotton vs paper
Hurricane (mesh) but very expensive and don't know where to even buy.

Whats everyones experiences and thoughts?

+1 for k&n. First thing I do with every stock car is change the panel with a k&n. The oil its designed to trap dust. Does no harm to your engine unless you use buckets of it.

I've also used K&N filters before, they are the goods for sure... I am currently using a Trust panel filter from Nick @ NST which seems to be doing a very good job

I'm running a TOM'S foam insert. I want to replace it with a K&N as I don't think it filters fine dust very well (if at all). The only reason people say not to run oiled filters is if you over oil them it ends up on your MAF, but a can of CRC MAF sensor cleaner soon fixes that. Mind you there's more oil in the intake of an RS200 from the PCV than any air filter could put in there so that totally blows that theory out of the water, plus you have an IS200 which are MAP anyway.

+1 K&N

-1 for foam unless you visually inspect them every month. Foam filters are great but they are prone to breaking down and being sucked into your intake (on a microscopic scale). They have the highest flow rate but allow higher particle sizes to pass. Paper filters filter the most but have the lowest flow rate.

All mesh filters require oiling. (all K&N are fibre mesh filters that are reinforced with stainless mesh). They are the best of both worlds but you have to keep them oiled every 10,000kms but you never have to replace them.

+1 K&N. Have used K&N in the last three cars I've owned. My Altezza came with a TRD one, and I have replaced it with K&N.

People always reccomend what they themselves have, for consumables.

For type of oil, air filters, tires, etc.

However, how many of you have done comparative testing whether that particular option actually gives any tangible benefits or not?

Using an oiled air filter on any MAF equipped car is a bad idea IMO, seems like only potential downsides with no benefits.

Getting the incorrect MAF readings can cost you more horsepower than any filter will ever gain you.

My car lost 20hp on the dyno, and a TONNE of bottom end when the MAF was getting incorrect readings...

With a previous (beams powered) car of mine, all the intake configurations I tried...
The factory airbox with a repco panel filter in it gave best equal, or better power than other configurations.

Okay so,

Here are before and after dynos, only change being air filter type:

Apexi pod, on aluminium bend to throttle body - 113kw atw

http://img95.imageshack.us/img95/6961/picturewe8.jpg

Standard airbox, with repco panel filter: 127kw atw

http://img219.imageshack.us/img219/7347/dsc00573ht9.jpg

Literally a 15kw loss, and BIG gain loss in low end by having MAF reading incorrectly.

Also interesting to note that the car FELT faster when it was 15kw down, and missing all of the bottom end.

Thats because you were using a pod filter mate. Google Altezza and Pod filter and almost every result will tell you not to do it unless your running an aftermarket ECU.

Oil filters do not effect MAF sensors unless you use to much oil. At least this is the case with a K&N. They also have one of the best micron (as long as its oiled properly) to flow rates available for a stock replacement option which is a very significant benifit.

Cant give you any qualitative results because upgrading to a K&N for myself is a set, check every year or so and clean where necissary job. I did 130,000 kms in my Celica and I never had an issue and they are guaranteed for life. How many times do you change your paper filter? They need to be replaced every 20,000 kms or so and how much will that cost you?

Anyone who changes the pannel filter and tells you they can feel the extra 10 or so Kw will probaly also tell you electronic turbos work...

Agree about pod filter... Was about 5 years ago when I did those dynos.

RIP Torque Performance monthly dyno days!! :(

But my point was that getting crud on the hotwire in the MAF can cause similar symptoms.

I've heard of people having to replace MAF sensor when coated in dirt or oil, which aint cool, those things are friggen expensive!

When shutting down the hotwire superheats itself to a high temperature to burn off contamination. Not sure how it reacts to oil though.

I guess what I'm saying is that I've not found a 'normal' paper type filter to be bottle neck, or cause poor filtration.

It's perhaps a different story if turbocharging or large displacement is sucking through a whole bunch more than ~130kw atw worth of air.

Thanks everyone.

VERY interesting reading.

My next question is the best places to buy each of these products and to cofirm the filter type.

Mine is a late 2002 model IS200 (caliente) manual.

1.) I've seen the TRD filter which wasn't what I was expecting. Was expecting the simple box size filter. Can anyone confirm. (I could go and rip it out and check, but if we already know.. it'll save me the time).

2.) Best Prices for the TRD, K&N, TRUST, HKS etc. and where to purchase them from?

Thanks again guys.

This is what the AS200 and IS200 1GFE uses and this is your filter.

Speak to Nick at Northshore Toyota Parts department. He is a forum supporter and you can find his information in the parts threads. He sells TRD and Trust filters but K&N will have to be bought at one of thier distributers (i buy mine through supercheap but a few online stores sell them for cheap).

Part number for K&N is 33-2845

K&N is a mesh filter, never has to be replaced under normal use but does require washing and oiling as required

TRD is a paper filter and needs to be replaced at least every 20,000 kms and cannot be washed (blasting them with compressed air such as air in a can works well but you risk dammaging them

Trust is a foam filter and needs to be oiled, washed and checked for degregation every 20,000kms,

Paper filters are the best to use by far but you have to replace them regularly and the cost blows out to five to six times that of a K&N filter over the life of the car

Modern Genuine air filters are good for 60,000 km so I'd imagine the TRD should be good for similar km's.
Every workshop in the world blows out paper filters with compressed air & it doesn't damage them so you're safe cleaning them that way.

Key word "workshop"

Ive learnt in my career as a service tech that even the simplest task can fubar any job. A mechanic knows to give a quick puff with an air compressor but some people are pedantic and some people also think bigger is better so when I made that statement I was imagining some bugger blowing 7bar of air into his air filter and ripping the paper from the frame trying to remove every bit of dirt and dust not to mention that air compressors are also known to blow water...

Once I told a the apprentice I worked with to do the oil change himself because he couldnt get it in the mechanics in time for his road trip. The bloke drained the gearbox oil and blamed me for suggesting it in the first place lol

Just protecting myself thats all.

Thanks Tezz-Winnie,

I'll look into these. I think I'm going to settle on the HKS super hyrid foam.
Don't put too many K's yearly and where I live the air is clean (australia).

Thanks Everyone.

The HKS flow very well, to well really. The foam doesn't stop much. Have a read of these articles http://www.mkiv.com/techarticles/filters_test/1/index.html & http://www.raceweb.co.za/Articles/airfilters/induction.htm They may just change your mind. K&N FTW!

K&N panel for me too. The only problem I've had with oil on the AFM was from engine blow-by at high revs, not from the filter. and @ $149 for a cleanable high-flow filter (that actually filters out stuff unlike foam ones) you can't go wrong.

The HKS pod I had on my skyline sounded awesome though (which is of course the most important thing about an air filter <_< ).
