The absolute best airfilter is the standard FG white foam one. Properly oiled it'll out-perform anything else. It doesn't look very good, but it's the best at filtering out the crap. All the aftermarket ones were made for scooters or strimmers (weed-eaters) and are not up to the job unless you clean them out VERY regular.

I'm speaking from experience. I had a K&N with velocity stack (let fine dust through) My brother had a Sikk racing AF (leaked and let dust in)

The best airfilter for these FG is the Pitstop Tuning by TWIN AIR off road filter.

cyberyn,

not sure i agree with you on that one? a good quality aftermarket filter made for r/c application will give an increase of 30percent more airflow than the stock one you mentioned, so in theory 30percent more airflow means better performance all round out of our engines

cheers

Unless you are on the cutting edge of the racing scene I have to agree with Cyberfyn the New FG filter has a large surface area from which to draw air as opposed to some of the after market goped style filters the FG filter foam is also thicker from outside to inside.

The Twin air filter looks to be even better than the FG filter but unless I can find 5 other people I can race against I'll stick to the standard with a small sock over the top not because I think it needs it but it makes the foam easier to clean.

Jimbo, you are right, the std fg airfilter if perfictly five, so long as you clean it and re-oil it regulary (sp?).
A performance airfilter, like the TWIN AIR one relly done improve the induction into the engine. it is a lot more responsive from start. Whereas the stock fg filter makes the car slugish from standstill accelerating, the twin air one is not. it is responsive as soon as you hit the gas, great not just for racing, but it will be good for just playing around in filds, parks etc... It is a well worth the money upgrade, spoken from experience.

guys

are you saying the stock fg filter performs better than aftermarket ones not including goped filters??? i will put a grand and two fg mt's side by side stock except one has performance filter not a goped one but r/c aftermarket one specifaclly made for zenoahs and one with stock filter? which one would you place your bets on cos from experience i can gurantee which one would win

not to say there is anything wrong with stock fg filter but there are much better r/c filters available to really tap into the full potential of our zenoah engines and thats from experience

Thats whats i said

The STOCK FG AIR FILTER is perfictly fine and will do the job, but makes the car sluglish
THE TWIN AIR FILTER WILL improve the performance and engine response.

SLUGGISH??? not in my experience so until I start racing for money the FG filter will do me fine.


P.S. Veron, if you read my post I stated that the "TWIN AIR" filter which I think is specifically made for the RC scene looks even better than the FG filter

Wow 30% more airflow! Where did you get those figures from? The FG filter alows almost unimpeded airflow, so if you can get 30% more than that, that puts you in forced induction territory (Turbo charged / supercharged)....Coooool. So how do these filters force air in above normal air pressure without any mechanical help then?

I need one of those twin turbo force air inducted filter systems
I am suprised they do not claim to increase HP

Exactly, and to add to that...... how does that filter clean the air better? If it's letting more air in it cannot be filtering it cleaner. Either retrict the flow to compltely clean the air of dust or let some dust past to increase air flow. You can't have both. At least not that I've seen.

Same as K&N filters for fullsize cars. They let more air in because they do not filter the air as clean as a stock air filter.

Hell run the car with no filter and get tons of air but zero filtration. You'll get awesome response and more power, but short engine life.

I'll stick with the stock filters. My cars are fast enough and the engines, carbs are shiny clean inside. I'm not racing for cash, I'm bashing.

here is copy of text on the airfilter system i was talking about quote.- ''Here we have a complete air filter kit with an alloy adapter to fit all zenoah and solo engines. This air filter will also fit most other make of engines that use a walbro carb including the st range of engines available from us. This air filter fits nicely between the rollcage on fg off- road models including the new monster truck. You will gain 30% increase in airflow from standard plus it looks and sounds awesome. More airflow means more power. The air filter is fully washable and at a great price of only £19.99'' sourced from www.sbracing.co.uk and they specialise in engines and engine tuning.

you can mail sb racing and i'm sure simon can explain how the above system can gain 30percent more airflow than stock and yes without mechanical aid

cheers

Use the stock filter and get a spare set. They come in a set of 2 and are pre-oiled for $10CAD (FG#6464/5). There is also a stock air filter that covers the whole filter (FG#6464/2). I have one and it works great. I've used it for over 6 months now. It works great in the rain and snow since it keeps the filter from getting wet. It's about $25CAD for it and looks pretty good too. All black and has a few hole in the back of it.

If you look up Selwa's conversion thread you'll see what I mean.

There also millions of adds out there on TV and print that make the same outlandish claims. Too bad they can never prove anything.

All you'd need would be a flow meter (simple ball in a hose with marked lines) and a vacuum cleaner. Test all the filters in clean air and measure the flow. Then test in dusty air while measuring the flow AND how much dirt makes it through.

Somebody would have to own all the filters though. And I guessing ZERO of the filters makers have the cahones to send in samples to be tested since most GREATLY exaggerate their filters values.

It would be nice if all the filter manuf. would send filters for RCUniverse to be able to test all the 1/5th, 1/8th, 1/10th filters out there.

See who really cuts the mustard. And who can't.

simon from sb racing has stated and you can email him for verification that the filter in question does increase airflow by 30percent and that is fact and not fiction

but i do agree it would be great to test every filter as mentioned to see which offers the best performance all round.

30% more than what?

My toilet paper is suppose to be 50% softer says the fluffy man and I say 50% softer than what, sand paper

Here is what K&N says on their site so should I take their word for it[sm=idea.gif]



"ADDING HORSEPOWER
WITHOUT COMPROMISING RELIABILITY

K&N Lifetime air filters feature High-Flow Technology to help your car breathe easier, giving you the power you crave without the reliability headache often associated with high performance parts - and because K&N is a Lifetime filter, it never needs to be replaced."

I sucked in so much dust through the K&N filter it made my Hoover jealous The filter was fine I just had to replace my motor

There is a statistic that states that 99% of statistics are made up on the spot. And I think this one of em

I couldn't honestly tell the difference between stock and K&N apart from the dust in my engine with the K&N. Hence my reluctance to try another when the stock one does a much etter job and saves me £50!

The K&N filter is NOT designed for these R/C's as the gaps in the filter element are too big, which alow dirt and dust through, this is not good. But the filter is design for real cars.

K&N also says "elements combine to offer optimum air flow for all performance Off-Road". They should be more concerned with the elements that it lets through than the ones combining
