Greek to the Max

iTrader: (2)

Has anyone really noticed any Difference with this upgrade? Has anyone dyno'd their car after making some simple mods like that.

Does anyone have a good website so I can actually see aftermarket parts for the maxima.

Thanks.

Turbo magazine reported 4hp at the wheels with their project car. Go to the links section of this site to find max performance parts.

Sorry but it ain't the filter that's the restriction, it's the airbox and ducting. If you want any real gains, get the JWT/Stillen cone or the Cold Air Intake.

I put the K&N in my 2K BEFORE I even pulled it off the lot (took it out of the 95' when I traded it), so I can't really speak for any difference it may have made. But I CAN tell you after about 10,000 miles or so I take it out, clean it, and oil it and it makes a difference in throttle response.
As far as cold air intakes, I don't think it's worth the money unless you also do a cat back exhaust, remember...More air in, more air out = HP.
I wasn't really looking for HP by adding the K&N, I was just trying to protect my investment - MUCH better filtration. If your looking for HP go with the CAI and cat back. Just my opinion..

Conflicting data exists about the K&N Panel Filter's filtering effectiveness. Take a look at:

http://www.amsoil.com/products/ts.html

FYI, Amsoil products are highly regarded among auto enthusiasts. In my opinion, their comments should not be taken lightly.

from the tests I've seen, the stock paper filters are the best at filtration. Most aftermarket units require the oil to trap the particles since their more free-flowing design would allow the particles to enter if it were not for the oil.

I know Amsoil is a highly respected company and they make a great product, but let's remember the source of the information - the bar graph they show. I really have a hard time believing that a well maintained gauze (K&N) filter has LESS filtering ability than a paper, I just don't buy it.
As for the Amsoil being better than a K&N? Well they may be, I don't have the test equipment to find out. Just don't believe everything you read, anywhere. If you look at the K&N advertising they claim the paper is way inferior to the oiled gauze - who can you trust in this world today?
Well I sleep better at night thinking that I am doing something good for my Max, I just have a hard time accepting the fact that paper is better ?!

I guess it depends on whose data you want to believe, 2KSE. Here's a little more info you might find interesting:

I have been running a conical K&N on my other car (ford) for about 70,000 miles and have not had any problems. Don't know what to do on my max? Any independent research done out there?

More pleats on the cone filters equals better filtration, or so I'm led to believe. Don't ask me why, though. I'm not an engineer.

This assumption that K&N/cotton gauze filter mediums are better at filtration than paper has been consistantly been proven false.

Ask the BMW guys or the Scooby guys in the UK. One of the BMW tuners did an actual SCIENTIFIC experiment using different filtering media to see if the claims hold up. And they found that they didn't. Sorry, but this is about as unbiased a study as your going to find. (you can find a link to view the results throughout the many BMW pages)

The fact is K&N doesn't filter better than paper. But the main question is whether the crap that gets thru is large enough to actually do any harm. My inclination is NO.

The second major claim to fame for K&N is the additional flow. The answer is yes and no. Yes if the filter is new/cleaned, no if the filter has over a couple of thousand miles on it. You can find some flow graphs from the above mentioned BMW test as well as the Scooby tuners web pages. As the K&N loads up w/ dirt, the flow rate takes a drastic nose dive.

Since I haven't seen the dyno testing from Turbo regarding the panel filter, let's assume that there is a gain in HP. In order to keep this gain, you're gonna have to clean the filter during the same intervals as you would change your oil, if not sooner. Is it worth it? As a gearhead, hell yeah!

The other assumption that the many pleats of a conical K&N is the reason for its 'superior' filtering properties is absolutely untrue. The reason for adding pleats is to add surface area for flow. This is FACT. The secondary benefit for more surface area is the ability to trap more dirt before flow is severely compromised, thus lending to a longer time period b/t cleanings or replacement.

Thanks mhgsx. I stand corrected.
