To oil or not to oil that is the question

[Rep732]

alright so I remember a debate about what filter to oil ..pre filter or the actual air filter. Im hung up in my head with what really needs to be oiled here. My tgn redneck pre filter came with a little card saying it is important to keep it clean and oiled. And my uni air filter came with a card reading the same jargon. So for the love of God what really needs to be oiled here! From the nitro stand point the pre filter is dry and the inner foam is oiled. As of right now I have a dry pre filter and an oiled air filter...let's here it

Depends really. Some say oil the inner and not the outer (like HPI), some say both. I'd just do what the manufacturer recommends, I oil my redneck and inner filter ?‍

I did the same at first and it got filthy fast

 

[DougStar]

Oil the inner only

 

[blackrain]

I only oil the inner filter

 

[Rep732]

Good enough for me ill keep the outter dry and oil the inner

 

[Phill2]

I only oil the outer.

 

[Phill2]

You can laugh.
My inner never gets dirty.

 

[Z.hb71]

never had an issue with the outer getting too dirty, i clean it about every 4 runs and it usually aint that dirty.

Inner... the original hpi filter was the best, and I've never seen a multi stage filter where you oil the outer filter. The outer filter is supposed to trap the larger debris, inner gets the smaller stuff. The oil helps to remove the smaller stuff.

What Sean said makes most logical sense. The outer prefilter should catch the big stuff...and the inner filter...the oiled one should be catching the small particles. Hense the oil on inner only. If I was to oil the outers on mine it would make it like one run and be a total cake of filth

I oil the inner only??

Oil the black and yellow foam. Leave the red dry.

I've run the HPI for 10 years now and I always oil the inner element. I oil the TGN redneck outer filter very lightly. It's so easy to clean and the oil adds an extra layer of protection. The inner HPI filters will eventually no longer be available, so the extra help from the oiled redneck helps to delay the inevitable. Rednecks are still widely available and much cheaper than the HPI filter set.

I run in very dusty and sandy conditions, I'd rather overdo it on the filer maintenance than have my engine suck down a mouthful of cylinder killing grit.

I oil both. Nothing wrong with the extra protection of the outer foam oiled. I also smear a small amount of grease around the inlet flange where the filter will clamp to so as to ensure NO fine dirt particles will get into the carb. Dirt/sand getting past the filter = blown crank bearings.

I oil both. I've been using this. No dirt in my motor. Good stuff.
