What obvious reasons are those?

You have an opinion on a preferred filter, it surely can’t be a state secret, particularly when you have no problem naming a brand you dislike.

Share it with all of us.

[SensationFG8]

I too would like to hear of this mysterious brand and see the supporting scientific evidence for why they are superior. Isn't sharing this type of info what the forums are all about?

[PHANTMXR6]

If he ever shares it I think you'll be surprised......

Yes but most here follow marketing guff not tech data. It's why people like
Snap-on fan boyz pay silly prices for their product to give just one example.

I have one installed other than my fuel use going up it does **** **** all.

[GasoLane]

I would be appreciated if everyone addressed the original question and avoided snide personal comments.

I think if you are replacing a stock paper panel filter with a k and n and expecting some serious power gains (like most uninformed people do)you are looking in the wrong place,they are only designed to flow better than stock and to be able to be cleaned and reused,buy a k and n and it will last the lifetime of your car,never buy another paper filter ever again and have a filter that gives better performance/airflow than a stock paper filter,win!
Seriously what kind of performance would you expect for $100 lol
If you want to feel a noticeable difference change the airbox to a decent cai and run a decent sized k and n pod,ive also heard good things about bmc but they are never readily available when ive been in the market to buy one,the supercar guys swore by bmc on dusty tracks like barbagallo.

Another thing to take into consideration when buying a K.&N. panel filter is that it will take approximately 6 years for an owner who does 20,000Kms a year of normal driving for it to repay itself!

Cost comparison;

(Assuming brand new car - say FG Falcon for the exercise)

K.& N. Panel filter @ average price of $100 + $20 for K.&N. oil = $120

Assume Ford original paper filter is changed every 30,000 Kms....

Genuine Ford Paper filter @ $26

6 years x 20,000Kms per year = 120,000Kms.
120,000Kms = 4 x paper filter replacements at every 30,000Kms @ $26 = $130
(remembering that you don't pay for the first one as it came with the car, thus only 4 above)

Above example does not take into consideration that there maybe fuel savings in running with a K.&N. panel.

Paid $82 for my last one and sold it used for $40, it lives on in another vehicle.
Paper filters go straight into the bin.

The case starts to build though for the S/C 5.0. Paper filters can be as much as the K&N, so it makes a lot of sense to buy one from a cost perspective.

That might be a fair comparison if you are still using a stock airbox.

I'd still prefer to be able to service my filter myself though.

FFS stop the trolling crap, post up why you don't buy them and why they are garbage so both sides of the story are told and people can form their own opinion based on that.

Otherwise close this thread.

[blackf6]

I use K&N. Purely for the clean ability. And the re usability.

If you read from post #1 you'd get it. Again there are thousands of UOA's available that show KN pretty much useless. Now either you don't know what a UOA is or you can't understand them?

UOA = used oil analysis, gives statistics of particles in used oil to check for possible engine issues.

Again, post up why you don't use them and don't give the UOA crap excuse. Post YOUR personal experience with the filter.

I ditched the one fitted to BMW purchased as having read more UOA's than I've had hot dinners I knew, as did everybody else, that they are a joke. It was replaced with a far superior reusable product. Is there some part of that you don't understand?

[Road Games]

Oh we understand who the joke is all right

Another troll for the Ignore List *sigh*

Please Continue Oh wise one.... Many other car modifiers on here can surely gain from your educational posts and save themselves money ?

Peace out

You have no credibility if you can't even answer a simple question

Answered perfectly. The fact you don't understand the answer is not my problem! I replaced an inferior product with a superior product as I will this afternoon when I replace plugs with superior NGK Iridiums. Get it now?

[Bossxr8]

Answered like a pollie in question time to deflect not answering the question.

You were asked what brand. You didn't answer it. And don't play the add 2 and 2 together and you should know reply. Just spit it.

In your case it would be beyond you.

Sprint man, do you not want to name the product for fear there might be an alternate opinion which counters your beloved UOA.
Or perhaps you don't want to share your great findings as you want to be the only one with a 'truly' protected engine. Or perhaps if everyone has one the price might go up.
Im guessing its the former.
However the question was asked and hasn't been answered.
What is the superior product you use in lieu of paper or K&N?

JP

[GT450]

Well now we know what sprk plug brand you use how a brand of air filter, or are we supposed to read your mind . As for the UOA , put up or shut up. Now can we get some peace.

Thousands at BITOG. But will you know how to read one?

Did, not do. There are many brands of filter superior to Krap & Nasty, I selected an Amsoil nanofibre Absolute Efficiency as A) it was the best available at that point in time and B) it was available in the correct size for my custom CAI, and C) there was a supplier on BITOG who could ship it to me quickly from the U.S.

[GT450]

Finally an answer for a filter you have used not just read about. As for Bob Is The Oil Guy , you worship whoever you like but do us the courtesy of being able to do like wise without the constant sniping. The forum is for sharing and helping not running oters down because their opinion differs to you. Don't BMWs have a forum for you to visit?

Amsoil? Do they have them at superchips?

[2242100]

Here's some accurate GPS measured rolling acceleration data collected with a Racelogic GPS based Performance Box.

Standard untuned FG Turbo Auto. Two runs, same location/direction, car in Drive, less than an hour apart, practically the same ambient temperature (1 degree drop by run 2), underbonnet temperatures almost the same with a period of cruising before each test and 1-2 litres of fuel burnt off by the second run. No wheelslip on either run.
So power/weight ratio should have only been about 1/4 of a percent better on run 2.

Run 1 done with no filter at all in the airbox.
Run 2 the standard (approx 20 k old) filter was re fitted.

RUN 1, NO AIR FILTER......................................RUN 2 WITH STANDARD FILTER FITTED

30-40 km/h.....0.45 sec......................................0.44 sec
30-50.............0.84............................... ............0.82
30-60.............1.26............................... ............1.24

30-70.............1.83............................... ............1.79
30-80.............2.45............................... ............2.40
30-90.............3.05............................... ............3.01
30-100............3.69............................... ............3.64
30-110 km/h....4.44......................................... ..4.38 seconds.

So surprisingly it was a fraction slower without a filter although it lost out between 60 and 70 km/h, probably due to an earlier 1/2 change on that run. But taking that out of the equation, it was about 1% faster when the filter was refitted when I believe it should have only had a 1/4% power/weight advantage.

To me that is just a minor variation that could commonly be found between runs and in my mind I'm thinking that it probably loses nothing with the stock Ford filter, so with that in mind I'm questioning if a K&N panel filter would improve performance in a stock untuned FG Turbo, although you might save money over time.
Also I'm wondering if it would be possible to actually lose performance if a K&N had too much oil?
