K&N Oil Filter - Performance Gold?

[8122pbrainard]

are we talkin boats or cars here?

Air filtration for cars and oil filters for both cars and boats.

Here is a pic of my old 96 Ski with a KN extreme air top on the carburetor (replacing the stock flame arrestor). This added a huge increase in HP and made the engine sound a lot like a car with cold air intake.

Installing a automotive air filter on the boat isn't safe or smart! A USCG flame arrestor is less restrictive than even the large surface area K&N filter. Did you dyno the engine which would prove this "hugh increase in HP"?

Well, the KN Xtreme Air flow top is not USCG approved, nor is any of my life jackets or beverages for that matter. I have used it for 4-5 years without any problems. It is not soaked in oil and it provides more air flow than no filter/arrestor at all because of the design (it spins air into your caruburater). If you want more info on it, go to their website.

No, i did not "dyno" my boat, who in the **** would on a tow boat? I know engines pretty well and owning that boat for 10 years gives me a little credibility about knowing how fast it moves.

How do you get away with the life vest part? That is like a $200 ticket per person here.
And are you drinking white lightnin out there?

Sorry dude but this whole statement is what I was referring too. If you don't have any real proof on your own you have fallen for the marketing teams best efforts. Swirling the air in? Really? I dont mean any of that in a disrespectful way but don't fall for it.

I have been modifying boats, cars, trucks, and atvs for 20 years and have read and fallen for more than my fair share of crappy power adding add ons.

Man I got a kick out of that. He is in Tennessee so their could be some shine involved.

Agreed, not safe or smart. Flame arrestors offer little to no restriction. Also calling BS on this "swirling" claim.

K&N does offer a USCG flame arrestor that uses an element that looks like the one used on cars- but I doubt its the same. Its also not worth the price tag- flame arrestors are safety devices, not performance parts. Ive run for short amounts of time with the motorbox open (or off) and no flame arrestor at all- performance is identical when the arrestor is installed.

Trust me, if there was any benefit to be gained from a K&N, I would have one installed on my boat. Spend the money elsewhere.

SS,
I took your advice and went to K&N's site. All the claims they are making sure sounds like marketing BS to me. Absolutely nothing to back it up!

Since you have owned a boat for 10 years and feel you have "credibility" then you know you are taking chances with not using USCG equipment. That's fine as it's your choice but to post your choice of not using USCG flame arresting is wrong and poor advice. There are some people who may look at this thread and not being as "smart" as youself will use the K&N filter on there boat. I'd hate to see someone else have a problem.

BTW, there are people who will dyno their ski boat engines!

Dyno Ski boat engines.

I have seen a water brake that measures torque, mounted on the propshaft of an Outboard motor.
PCM must have some way of measuring the output of the motors, but that is probably in a test stand, without a boat being in the way of access to the motor.
On the other hand, you probably could collect data from the computer of a modern engine, measure the fuel consumption, and come up with a pretty good estimate of the power the engine is putting out.
That would require a modern engine with a computer on it.
Or maybe you just need a calm day, and several barefooters to load the boat down.

[bobchris]

wow what a bunch of BS try actually reading the website, says nothing about swirling the air, says pulls air through the side pleats. Nice automotive equipement your using and then don't even follow the instructions where you need to add the oil because that's what attracts the dirt and holds it in the filter and how they are able to open up the media for increased flow without increased dirt into the carb.

Amazing life jacket is not approved might not be for skiing or class IV I think but they are all rated by the coast guard federal law idiot, another bunch of BS from super squirt must be getting a hold of himself too often and it's effecting his vision and ability to read.... what a tool.

first of off the engine is dyno on a stand it's not a car and several people have done it so that you can dial in the the advance curve and fuel curve. And there is no way in he ll that you are going to pull info from the engine's computer to get HP or Torque info like you are pull this crap out of your rear.

Yea, Id like the see the Dyno on that K & N air filter! More HP than the flame arrestor? I doubt it. What salesman sold you on that. Air filters by nature restrict the air much more than a flame arrestor. The percent of true air flow opening on that K & N I bet it is less than a stock flame arrestor. Now since the top is open it may sound like it has more HP.

Now if I were gonna take my boat down a dirt road it would be by first choice! :-)

it's not any different than flow testing heads

but here read on for you self pretty self explainitory, more flow more HP plain and simple, now will the average person notice... maybe not.... will it be noticed easier on a highly modified engine that pumps more air to start with... you bet it does.

JUST STICK WITH THE STOCK FLAME ARRESTOR AND STANDARD OIL FILTER!

An air filter on a boat? Why not just throw your wallet overboard to reduce weight, you may get a 30% increase in HP.

[jaybird]

I read the test method! ??
I would say K & N pays its Marketing and Advertisment personnel more that it engineers.
Its makes perfect since while making no sense.
Typical Marketing BS
