kenknox

Easy to use although I found my oil lines going to the filter housing were backwards when all my oil gushed out of the air cleaner. Seems the check valve in these filters only allow the oil to flow one way. In looking at the HD manual it is very vague as where to put the oil lines so I suppose this filter is a good thing

jeffreyu09

Easy oil filter removal/w nut on filter. Great quality!

brandolphdpm

Nice, but I ordered the wrong size.

walt9064

Good price and quality.

sleprock40

Easy off and on and I always use K&L filters on all my vehicles

name1492

Got lazy in my old age. Just like using nut on end of filter

mav4140

K&N products always excellant quaility

pilotmoss

good price, good filter

payanni

Great place to buy parts for my bike . The prices are low and shipping is quick. Way to go J&P.

Jan-Ivar

fits great! is it better than a stock filter? dont now!

emphacia

Does what it is supposed to do.

Nosage

K&N is the best in filters. I like the hex bolt removal nub.

Scooter1228

What can be said but it's a K&N, wouldn't use anything else

rgrosshd@aol.com

Fit my 1981 FLT Classic.

bp88

Probably one of the best if not the best oil filters out there for your Harley. They're a little extra but I don't mind paying a few more bucks for peace of mind and ease of removal with the nut on the front of the filter housing.

Ev Card

Nut stripped. dented the hell out of it to get it off

chryco

Looks Great!!

1983fxrt

The built in nut for removing the filter is great since my filter is down under.

fife

Spins on and off with a breeze, just what I ordered

Mck486@aol.com

Quick delivery

jkyler

I always use K/N filters on my bikes and vehicles.

wteipen

Easy to install but the nut is useless if you've over-tightened the filter. I hand tightened the filter (guess I don't know my own strength) and still had difficulty getting it off at the next change. The rounded edges of the nut made it difficult for a wrench or socket to get a good grab and the nut strips easily because it is made of very soft thin metal. I ended up having to destroy the filter to get it off using the screw driver method since HD put the filter where a filter wrench can't get ahold of it. Grrr.

carslut

realy like the built in nut, makes install realy easy

mph1976

Simply the Best

carslut

easy filter to install!

PUSA

Good price

fenianbiker32@aol.com

This thing cleans particulate matter from the oil!

blackbert

at least i know i'll be able to get this one off without having to destroy it like the filter that came on the bike from the factory overtorqued.

smittyok@gmail.com

Great quality product

jalucch1@msn.com

seem to work fine

juniorj1980

Very pleased with the product

johninwaegwan

Did what it was supposed to, filtered oil utnil it was time to change.

hgfbean

k&n filter. top quality. great fit. replaces stock filter on my 09 flhx.

neptune89

There is no better oil filter than a K&N oil filter. The bolt on it makes removal so much more user friendly.

flem469

Best oil filter on the market, in terms of protection and ease of removal/installation.

pegasus90

Quality item at a great price.

Charlie1162

Great replace for H/D...don't need that special oil wrench, but you should get the filter drip catch it works too

mikebizz

better than stock for oil change

cdyoude

excellent and with the hex on the end I don't need to buy any special tools to replace it!

cdyoude

rwdhawkins

good product. a little hard to get off, but gets the job done

iras02@comcast.net

Nice Oil Filter from K & N. I used their air filter too on my bike! Fit easily on my bike and no drips!!

slotboom

Theses filters are great. Easy on easy off, no fancy wrenches needed. Would recommend to anyone.

Big Buck

Good deal with the nut on the end. An accessory on my frame makes it difficult to get a cap style filter wrench in there.

rebelbob6901

Like the black filter as I have blacked out most of chrome with powder coat. Besides it stays better looking than chrome.

hdgeo3

awesome products,fast shipping.always great service from j&p.

wagnergforce

the filter is exactly what I ordered

4951tomm

A fine looking oil filter....

EdwardLake

What can I say? It's a K&N! Nut on the end makes changing your oil a breeze.

r1ckyc

Nice easy to change filter. Oil appears cleaner when checking it and when draining it after 3,000 miles.

oursaway

Much better than I can get at Harley. Nut makes the filter change easy.

et290

Why not use the best. K&N has more filtration than most all others and it is easy to take off and replace with the nut on the end.

chad24

Lot easier to get on and off compared to filters that need an adapter. Adapter always seams to slip will use these from now on.

DJBaar

Does what is needed to do.

vinceeer

I only use K&N filters, they are the best.

rmhare56

Great filter at a great price

rmhare56

Great filter at a fair price!

Pidgeon

The little nut on the end should be on every filter. Back to 10 minute oil changes.

ole trucker

The best as far as I am concerned! The chrome looks nice, but retains heat, do not need anymore heat around Florida.

chadmoto

K&N rocks the filter world and these meet or exceed my expectations

therod

Top of the line filter. Has a nifty end on it so you can use a wrench to snug down the filter.

par031@gmail.com

Received very fast, and K&N always has great quality

windham1

This product was all I hoped it would be!

Kevin42

As far as I can tell, this is as good as the last one, I would prefer a chrome one.

leeelectrical

EZ to install and EZ to remove with a 17mm tool

lunalos

Easy to Change!

MVHP2

good product and service

Charlie1162

for 2007 V-Star 1300..great replace for stock.

jwhite1129

Very convienient .. one stop shopping!

impulsv1

Great filters

sleevedbiker

great product

nikoudimitrios

No.1

rnrcarpet@att.net

fast & fit great

scooter0524

Worked very well...I think I like the maxim chain wax better though as it is less messy.

beamsbox

As expected. Good condition. Good price.

jeffvanhoosier

Love the 17mm nut, no more oil filter strap wrenches!

Frank1966

Great deal!

v99nomad

the sales man was very help full. I got the right filter and oil for my bike.

slicernine09

great works like a champ

momule

No cardboard or cheap filter elements inside. Nothing bad to say about it...it filters and being black is almost invisible on the bike. Works for me...

momule

Not having testing equipment all I can say is that this filter is the one that I always use and it has never caused me a moment's problem. I could buy cheaper and I could buy much more expensive but I trust K&N products having one of their cold air intakes on my Honda Civic Si. I change the oil and filter every 5K miles.

roncal484

We only use this oil filter from you guys. Have had no problem with them. Very satisfied.

jleonard1

Best filter for the money.

emphacia

Does what it is supposed to do.

Existentialmike

Wouldn't use anything else.

starlightpainter@cableone.net

Have used KN products for years. They are just the best out there.

tomsplace2011

shipped fast.

Bulls488

Great filter

curtisbjohnson

Works like it is supposed to. The built-in nut on the end makes it easier to get off during your next oil change.

vicarc

Good filter and easy to install and remove.

lajumper@st-tel.net

Great price, awesome customer service!! Thanks Again J&P!!
