i know been talked about , but whats the best filter for my 2010 110 ci street glide ,, thanks

[CHH_Badkarma]

HD filter meets the spec called for. Amsoil does as well any "may" exceeded in some areas.
If you are looking for standard disposable filter it's hard to beat either of those two

[laylonlor]

thanks

Easiest to change, works well.

[ultrarider123]

I have used the KN 171B for the past 4 oil changes and really like them.  Watching the oil pressure when idling hot, the pressure seems to hold a bit higher using the K&N (around 10 psi) from using the stock HD (holding around 4-5 psi or less) under the same operating conditions.

The nut on the end (of the oil filter, not the one behind the handlebars) does allow for easier removal during changes.

[J.D.]

I've used several different aftermarket brands and even cut them open to inspect after use.  I should note that I prefer the look of a chromed filter vs. painted.  Hard to beat the MoCo 5 micron IMHO.

[CHH_Badkarma]

Just remember, the micron rating on most filters is under optimal conditions. I forget the term used for the test,  but most manufactures rating is not what the filter is filtering all the time. Most times will let material pass that is much larger.
Forgive me being vague, I am on my phone and not in a situation where I can reference the info that I could normally from my desk top.
Perhaps someone that is more available at the  moment can.

That being said, filters mentions above will get the job done.
However if you have money burning a hole in your pocket and get a warm fuzzy feeling that many of us do from spending lots of money on parts there are more costly filters out there that may or may not meet minimum spec (depending who you ask) like K&P stainless mesh reusable filter. Not to be confused with the K&N variant.

Use a good filter, use quality oil and change it regularly and your motor will thank you for it.

[NH Bulldog]

My personal preference after two year factory warranty has always been the K&N, with Mobil One V-Twin, but that is just me. 

You can read about filter efficiency and micron size (the smaller the number, the smaller the particle it will filter), you can read about filter bypass (when filter is too restrictive due to cold oil or clogged filter media, it bypasses the filter altogether).  You can read about oil temperature, viscosity, oil shear, thermal breakdown, etc.  I am sure there are people here with 100,000 miles on their bikes and only ever used OEM filters.  There are some that only change their oil every 10,000 miles or longer.  But there are also people who needed a new motor after 18,000 miles and changed their oil every other week.  In the end, it is whatever makes you sleep better at night.

Somewhat off topic.....however does any one use an oil extractor pump for oil  changes?
How do you like it?  Pros and cons?  What about the scavenger system for getting ALL the oil out of the engine? 
Looking to make my life easier and or less expensive than going to the dealer....my 5K maintenance was $400.00!

I thought the 110s required a 10 micron

OR the K&N 171B if you don’t want to pay for the chrome.

Never used an extractor on my Harleys.  Used to use one on my boat.  Never got all the oil out, but most of it.  Easier for me to get a drain pan under the bike & remove the drain plug & let gravity work.

The K&N

[J.D.]

What is the advantage of the K&N filter that warrants the premium price?  I personally don't need the end nut as I have a proper filter wrench.  I didn't see anything internally that would suggest it is somehow better than the HD filter, but then again I'm admittantly not an oil filter expert.

I shop the K&N (usually on Amazon) and get them for $3-5 less than I can get the Harley filters for...
I'll also use Mobil1 filters(made by Champion Labs, same as HD) when I can catch em on sale at Pep Boys...

[trippy]

WRE4U,

Have been using the "Savenger sytem" for a couple of years now, works well.

[grc]

All the filters offered for Harley's have become overpriced, probably because the companies selling them use the overpriced OEM product as a pricing baseline.  As mentioned above, look for them on sale the same way many of us do when buying oil.

Harley used to claim their filter was 10 micron, then magically they changed the print on the box and it became a 5 micron filter.  As best I can tell, it's still the same filter.  People get caught up in advertising hype and BS, instead of actually studying how these things are actually rated.  Just be aware that some of the beneficial stuff in motor oil is larger than 5 microns in size, then think about that 5 micron filter claim.

Jerry

btw, for those who don't know, 1 micron = 0.00004", so 5 microns would be 0.00020 inches.

I get the $15 MoCo filters @ 20% discount ($12).  Haven't found the K&N chrome filter for less.  I've never had any sort of problem with these (leaks, oil pressure issues) and they seem to have a nice filter element that isn't the old fashioned paper so I really have no reason to switch.

[iski]

This reminds me, aren't we past due for another "Best Oil"  argument  discussion thread?  I think there is a thread quota that is supposed to be met for any board where engines are discussed?   

[bakon]

Gave up on the kn filter. Don't like it only seems to grab by a thread or two and also isn't always a standard wrench size with the fake chrome coating. Also last change in a rider who doesn't keep her bike as clean as others, lots of rust on the chrome bolt and it's surrounding round pad which is placed on the end
No problem with hd filter but went to the Hi Flo to see what they are about to save a few bucks. No return changed in one of these yet.

K&N knows about this problem of only grabbing a thread or two problem.  They have changed the depth of the inner flange to give full thread engagement.  They sent me two new replacements for my ones with the problem.  They were fine for many years then not to long ago they changed the design which created the problem.  Now they have corrected it.

Used to love K&N filters until they began to show up with "Made Anywhere But Here" printed in microscopic print on them.

I questioned it with the company directly and they responded with the price point argument.

Had to chase out the threads with a tap on the last K&N purchased, just to get it to screw on and I am now done with them.

They may have since improved, but I cannot get past "made in china, or taiwan, or korea,or whatever".

No point in cheaping out on an oil filter, only change it once or twice per year.

[rigidorbust]

what a bout those, FLO Oil Filters Polished FLO Stainless Steel Reusable Spin-On Oil Filter,are they any good

[ultrafxr]

I've never used the K&N oil filter.  I have used many of their air filters on bikes and cars but the oil filter never interested me . . . because I've seen how much force sometimes must be applied to unscrew oil filters.  On my 2012 with the oem filter at the first oil change I had to use so much force that it actually deformed before it finally gave up.  Now obviously it was put on way too tight from the factory and even though I am careful not to overtighten during installation over time and miles the filter can still get stuck.  A friend just started using the K&N filter and raved about the hex built in made it so easy to remove until one time the filter was stuck and the hex deformed to the point it was not functional.  Had to drive a screwdriver through the filter to twist it off.  Heck changing the oil filter on a Harley touring bike is messy enough without having to puncture it through the side.

[J.D.]

Wiping a film of clean oil on the rubber seal then only hand tightening when installing usually is enough to ensure easy removal of most any filter.

What he said ^^^.  I know it's not popular, but following instructions is usually a good idea and can prevent mistakes that create problems and extra work.  I wouldn't blame the filter, I'd blame the person who didn't follow instructions when it was originally installed.  Btw, hand tightening doesn't mean having your buddy with the huge arms and hands crank it down until it won't budge. Start by cleaning the mounting surface (often ignored), apply a thin coating of fresh motor oil to the new filter seal, spin the filter on until the gasket touches and grabs the mounting surface, then turn approximately 1/2 to 3/4 revolution by hand.  Read the instructions on the filter box, some call for 1/2, some for 3/4, some for a full turn.  If you follow the instructions, the filter isn't going to fall off going down the highway.  I assume that fear is what leads many to crank filters down way too tight.

K&N filters with the hex nut say no need to pre oil the gasket I believe.

They are already coated with a tacky lubricant.  I still add a thin coating of clean oil anyway.

I'm sorry Jerry.  We all know it's harmless.  This just hit me funny though  .

I use one similar to this but no hex nut on end....I like yours better. 

I also like the K&N that has the nut on the end. Before I take the filter off, I poke a whole in it using a dry wall screw to drain what oil is in the filter.....no mess.

[J.D.]

That's a great hack.

Best thing I've used to minimize oil mess is a (unused) disposable baby diaper.  Just stretch it out a bit and stuff it under the filter.  Go ahead and laugh but these things soak up hot oil like nothing else.

I have found that Luvs size 3 seem to work and fit the best.

What brand and size diaper do you use?

[J.D.]

I honestly have no idea.
