Desnorkeled my Boxster on the weekend!

Ill probably have 1-3% more dust particules that will settle on the cyclindar walls when the engine stops but once the engine is running and igniting that feul, the dust will run its course through the head, then the cyclindar, then back out the head, then out the exhaust....remember, we are talking particules, not rocks.

Hi,

Your information is uninformed and anecdotal. The K&N Filter will not filter anything smaller than 30 microns with no Oil as opposed to 5 microns for a paper filter. Also, most of the dust you refer to is composed of Silicates which are harder than the Alloy used in the engine and will cause premature wear.

You are also wrong about the dust not getting into the Oil, this WILL occur and will then circulate through the Oil Galleries and Bearing shells (which are again softer than the engine alloys). Using the K&N will be comparable to living in a High Dust environment and Oil s/b changed at 7500 mi. or less. This has been repeatedly shown in ISO 5011 Testing.

Also, the K&N will clog in 1/3 the time of a standard filter totally negating any supposed gains. The Filter has bigger holes in it, and so it admits more dirt/dust into the engine and the Oil - where do you think the dirt in your Oil comes from? Some are combustion by-products, but you'll find substantial silicate content which isn't such a byproduct.

You can do as you wish, but I hate to see anyone deliberately abusing fine machinery, especially due to ignorance and passing this misinformation on to others. Any way you look at it, it's a bad move...

Happy Motoring!... Jim'99

for Porsches is that there seems to be a supposition that the Porsche engineers either don't have the time, money or smarts to get every last bit of HP out of their own power plant. That strikes me as just a bit presumptive.

Automotive engineers, I think, try to design a powerplant that will --hopefully-- provide maximum output over a range of operating conditions and operate reliably
for an extended period of time.

K&N's goal is a bit more modest; it markets a product that lets more air through an automotive intake system than a stock paper filter--but with the downside that it doesn't filter as well. Given that the HP increase is marginal, if any at all, this strikes me as the worst of all automotive bargains--paying more for less with a big potential downside.

Or to put it anyother way, if the product was so great that it could magically add 5-10HP with no downside, wouldn't you think porsche would make it the OE air filter? Seems like a much easier way to get that last 10HP out of a car rather going from vario cam to vario cam +.

Then again, it's your $

Welll... don't discount the fact that the engineers are trying to hit noise and emissions targets as well. There ARE things that the engineers have done that by nature suck up some of the power of the engine.

But, I haven't seen anything that provides real horsepower gains on these cars that is cost-effective in any way.

This thread is hilarious!

Maybe this is a good time to bring up some other mods I am planning:

1) Replace airbag receptacles with handy storage area for my knives
2) Dashboard mounted hibachi for those long road trips
3) Fill up gas tank with alcohol for maximum performance like those top fuel guys

dude bro engine oil is so like 1989. Don't worry if it gets
dirty with a silly paper filter. I know guy Emilio who hasn't changed
his oil or air filter in 20,000 miles and the car is louder than an STI on
exhaust roids. I can hear my bro coming down my way like five
minutes away. **************** is bad ass, speed? Pfffttt who cares?!

p.s.

Come on, Perfectlap, you need to get out a little! :

Actually, it's probably because Perfectlap gets out that he doesn't know who Ron is.

That was indeed a great Ron Popeil reference.
