It comes up from time to time, there are a few try another search. Anyway, they are pointless, for a 1/8th off roader or monster truck, the mugen single stage foam filter is unbeateable. Send them a link to this post if you want.

what foxy said. unless they make a foam one. the paper ones are crap for nitro rc.

Yep, I've heard a lot of people say they actually let more than air through their filters into the carb which is never good. That's why most people use them on show trucks for looks. I would use a foam one with a pre-filter if you really want to be safe.

More air is good but they all so allow more dirt to get in, which is not good! I run a K&N on my Harley but I do not run it in the dirt. I would never run a K&N on my RC vehicles.

They coould possibly be good for on-road but complete crap for off-road use.

Did you search the Monster Truck forums?

Foxy

No good for on-road cos of weight and size. Too big and heavy for a 1/10th, and would stick up way too high on a lola 1/8th body.

i serched all the forums for K&N then K&N air filters and found nothing, but i'll send them this link.
Jeff
also i will let you guys know what they say.

They are superior filters for their INTENDED use, but since the applications they are intended for do not call for filtration of very, very fine particles, they do not work well for our R/C applications.
Reason being, our R/C engines are incredibly sensitive to very fine particles. 1/1000" of wear is a ton of wear for a piston that is 1/2" across, however 1/1000" of wear on a piston that is 2" or 3" across is basically negligible, especially one that has rings and an actual oil system.

I have a good idea what they are going to say as is any manufactory going to say any of their products are not any good? But yes let us know. I did a search and found these. I know this has been discussed many times and the search on here is not the best.

And there is more but you get the idea!!!!!!!!!!!!!!!!!!! They are good for what they are made for but not off road RC and the filters they sell as RC filters are nothing but 1 to 1 crank case breather filters. Try one and let us know how long your engine last.

Foxy

Yes, that goes without saying, it's the first mod I do to any full scale car. K&N 57i kit.

ok they replied here is what they said.lol it dont make much sence to me.

Dear Jeff,



I don’t think the thread came across in the e-mail. Is “K&N air filter ruin nitro RDC engine� being said by the web sites selling the filters or over forums?



Look forward to hearing from you and thank you for choosing K&N,

If you are not convinced then I recommend you run one and make up your own mind. Just make sure you have a spare engine.

I wouldn't even think about intsalling a K&N on my truck because I go to the dunes way too often to not worry about sand getting into the engine. Only way I'd get a K&N is if I put on an Outerwears prefilter/cover on it.
