K&N Air filter - Page 3 - PeachParts Mercedes-Benz Forum

Get WIX or OEM. I showed the differences in a thread a while ago between the Wix Puralotor and K&N. OEM/Wix had the highest number of folds == most amount of surface area. The k&n had the lest number of folds == least amount of area. How are you going to pass more air and less dirt with the least amount of surface area?

Does AC Delco make cone type filters?

Edit: Nevermind

ACDelco Air Filters are available in panel and round styles to fit most vehicles

I'm sure you could find a round type with a 2 - 2.5 - 3" mouth that would seal well on the tube. That's what I'm doing, for now...

My intake tube is 3". Did you just plug the other end of the round filter?

Filter Efficiency is a measure of the filters overall ability to capture dirt.

In the chart below it’s important to note the different test durations for each filter. The AC Delco filter test ran for 60 minutes before exceeding the restriction limit while the AMSOIL and K&N tests each ran for 20 and 24 minutes respectively before reaching max restriction. In 60 minutes the AC Filter accumulated 574gms of dirt and passed only 0.4gms. After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms. Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt.

The Amsoil filter tested here is the oiled foam TS series and the TS123 is used in later model GM pickups and SUVs. They have a new nanofiber filter (EaA series) and I would like to know if anyone knows of any test data like the above with the newer series filter results. Not the "results" from the Amsoil tests but some independent comparisons. Out of curiosity go to amsoil.com and see what they say about their new filters.
Thanks.

Plug what end? You must be thinking of round like what the stock setup uses. I'm talking about ones that are cylinder shaped.

Untrue. If I was going to keep my 95 for a long time, why wouldn't I buy ONE air filter for it???

Or I can buy 10 paper ones? And throw them away when done.

K&N makes sense for a car you'll keep for a while. For the economy of it, not for the performance. My CHevelle is faster with an AC filter by a tenth. Clean paper flows best.,

Everyone already knows that.

I'd rather buy 100 paper filters before letting a K&N on my engine. It's part of normal maintenance and you only have to do it once a year.

If my labor for cleaning the filter were free, and I thought that the K&N did as good of a job as a paper filter, I'd have one on my car.

Turns out that I value my labor quite highly. I can buy two paper filters for the time it takes to clean the K&N once.

I tried to send you an email -- I have a cone filter setup I just removed from my car. Drop me a PM if the email didn't make it through.

This says it all: "I'd feel better about it if I couldn't see so much daylight through this filter though."

The cheap paper filter is designed for your car and better for it.

Does your car have a MAF? I poorly oiled K&N will kill a MAF.

Yes this needs to be factored in. Time to change a paper filter, 5 minutes.

Clean and re oil a K&N what 20-30 minutes? Screw that my time is worth more.

what is the method used to make the oil bath setup refered to ? I have a 54' GMC pick-up that came with one as standard and they claimed that an oil bath air cleaner was the most effective type there was ---and the research is only 53 years old. But the idea of a permanent filter is appealing if it really is effective. how about an oil bath prefilter andthen the stock paper set up too, maybe only have to change the paper every two years...

I'm having to go to bed so i can get up early, but I will explain in detail tomorrow for all of you what I did with my K&N! No regrets!
