how to properly oil outer air filter foam
#16
I use the Pro Honda / No-Toil filter oil and cleaner and oil both outer and inner foams.
The No-Toil oil sticks like nobody's business and clean up w/ their bio-degradable cleaner is seriously like 1,000 times easier than the old Dawn method. Literally 4-5 squeezes in the cleaner mixture and they're spotless. Stuff rocks!

Its not really a big deal if a few tiny dust particles get into the engine, it won't ruin anything. In fact i ran several laps the other day when my filter fell off and i didn't even notice it. No damage was done to the engine. In fact airplanes and boats don't use an air filter at all. Its just the larger pieces of dirt that you don't want to get into the engine. That will scratch up the piston and sleeve and could ruin the engine very easily.

i'll just take your word for it ! especially since i don't follow my car around the track making sure it doesn't ingest anything bigger than 8 microns. i'll keep running my airfilter...no offense

LOL i'm not advocating to not run an air filter. Did you not read my entire post? Damage can be done if you get sand and dirt in the engine. But to think a few pieces of dust will ruin your mill is absurd. My point is oil the inner filter, keep the outter one dry and be done with it. Or oil them both, it makes no difference. You'll just need to clean the outter filter or change it more often.

Oiling the outer filter is going to cause more problems than it helps for exactly the reason posted in the pictures. these motors don't suck that hard that we need 3/4 of an inch of oiled foam to catch all the dirt. The mbx5 came with a single stage filter and they worked fine, a lot of people still use the ofna universal filter elements which work too. The purpose of the outer filter is the keep the inner one from caking up and causing a clog. The pre-filter helps keep the big stuff from sticking and fall off for the most part.

I picked up one of those filter covers for 8 bucks on eBay and was well worth the money! I run on a very dusty track and always get a plastered dirt film all over my filter after a race day! Started running this cover and it's like brand-new still!

Correct Air Filter Use
Hello fellow RC enthusiasts. A Very simple tech tip on air filters .
Off road filters
Normally these are 2 stage ie Inner and outer foam. The reason they have 2 stages is to offer a 2 stage protection to your engine and to allow you to simply remove and replace the outer foam for quick maintenance between heats.
The age old question is " Should we oil both stages ? " . And the answer is YES ! for off road applications you MUST oil both stages. What’s the point of having 2 stages if you only oil the inner one ? what you will find on engines that have only the inner oiled is pre mature wear, piston scoring, dirt or soot build up on internals, poor performance , flame outs, bad or irratic behaviour , poor fuel economy, short plug life … and the list goes on and on, these symptoms will accumulate over time….. “ But it gets dirty “ Um … its supposed to … err it’s a dirt filter .. umm, it filters dirt … you get it ? Stop being a show pony worrying about the dirt on the outside of your filter and clean it . How are you going to tell if its time to change it if you cant visibly see that its dirty ?
the dirt is an indicator that 1 its doing its job, 2 its time to change it to a clean one ..
When you run off road you subject the engine to fine dust , silica , rocks , grass and generally things they don’t need to ingest. The outer foam if oiled correctly , will protect the engine from these lager bits getting through. Also the oil you use is very important. Generally the thick blue gluggy motorbike stuff is going to choke your engine if you use too much. Give both stages a light liberal coating and wring out the excess. We make an oil called 3 in 1 and it’s a good medium for this purpose, or use the red K&N Spray bottle , its awesome too. It traps dust and dirt and still lets the air through without clogging the filter.
And before you tell me .. “ But my friend says you don’t need to oil both stages “ Let me ensure you that your friend is WRONG ! When you take the time to filter gram oil out of a pipe and see what actually gets through a dual oiled filter under a 100 micron digital scope, you will never run a dry outer again !
Fastening
You should fasten the filter to the carb with a good quality cable tie and have it on there TIGHT ! You should be able to pick the car up from the filter. Put a dab of oil inside the neck where it joins onto the carb to make a nice seal. Clean the inner foam filter every hour of use or when it becomes visibly dirty.
Outer foam for competition use should be replaced every 10 mins of run time.
Clean it with a decent degreaser and warm or cold water , wring out and allow to dry before re oiling.
On Road
Its just as important to oil the on road filters but you only have 1 stage and generally less dirt but you still have dust on the track that can get sucked in. make sure you check the filter foam where it attaches to the carb neck. Sometimes they detach.
Boat and plane guys don’t use filters. This is because there is generally less dirt and dust in their environment.
Now regularly clean and maintain your filter. Check for any tears , cracks in the elbow or foam.

dirt/dust is a killer. you might have gotten lucky and nothing go in the engine itself. but i can tell you a extremely small piece of dirt will ruin ANY engine. i have had it happen racing motocross, the airfilter boot came loose some how and it sucked in dust some how (no chunks or anything) and fried my piston, dirt is a killer.
