Air filters (which is the best)

[Purenitro]

I read a thread not too long ago about the Motor Saver air filter vs the savage X filter. In the thread some were saying that the X filter is just as good as the M.S. In terms of being able to filter the particles of dirt from the air, I believe this is true. As far as performance goes, I have not seen a better filter than the Motor Saver, and here's why.

In the pictures below I measured up a Motor Saver, HPI X and an Ofna Filter from my X1 CRT. The first picture is the I.D. of the tube that goes between the filter and carb. The Motor Saver has the largest one followed by Ofna and then the X.

This next picture shows the I.D. of the opening that lets the air flow into the tube. Again the Motor Saver takes it, and by almost 4mm over the HPI X filter.

These last pictures is where I feel the HPI X filter falls short in terms of air flow. As you can see, the Motor saver has zero restriction from the back plate forward which means it has direct airflow to the 12mm hole. The Ofna has some restriction but is still pretty open. The HPI X filter has less than half of the tube open to let air flow through and that's without the added plastic guard that fits over top of the tube.

My opinion is that the Motor Saver is the best filter on the market. I'm not saying that the HPI X filter is crap, but I do believe that if you are looking for the most performance out of your engine then the Motor Saver is a good investment.

make alot of sence since alot of carbs these days are getting bigger, and well whats the point if your using a restrictive air filter, this is something that has bothered me for a while, Ive always wondered if there was an affect on performance but have never heard any complaints, looks like I'm gonna be picking up a motorsaver, my filter is pooched anyways.

I wonder what the new motorsaver will compare to

Have you tried THIS HPI filter? I'd be curious to hear what you think of that and how it stacks up to the stock HPI filter.

That is a motor saver filter as well, hpi must have put their name on it. I just bought a "hpi" filter for .12-.15 engines and it was a motor saver as well.

Question...is this the right filter even though it says "T-Maxx 2.5R/3.3 Air Filter"?

I think this is the one you need to look at FX http://www.motorsaverfilters.com/savage.htm

That t-maxx filter has a big restriction at the neck, not sure why they designed it that way. ryugaiden05 has the correct link for the ones you want, I have yet to try the newest one but it looks massive.

I'm gonna order one from Tower Hobbies. I'll let you know what I think.

Pure-I think they did that to get around some linkages or something, I'm not 100% sure thought.

I as well have been running Motor Saver filters for a long time on most of my stuff and love them with no problems.

 

[Purenitro]

Yeah I think your right Larsen, I don't run them so I'm not sure why but I think that's the reason.

awsome info purenitro, i've always wondered what makes the motorsaver air filter better and now i know!! lol

 

[texasavage]

Great Thread! Thanks purenitro! :resp:

 

[frddyj]

i like the design of the sealed case on the motorsaver. recently, the foam on the hpi stock savage filter moved back on a crash & mud got into my mill.

:turtle:

 

[DGCON]

I'm gonna go with the motorsaver on my 5.9. So is that what you guys are running on your modified picco .28's ?

 

[tornacl]

Mannn mud in the mill ... thats a NOOB mistake Freddy !

But I do agree with ya on the new design on the motorsaver ...
