alternative air cleaner for D-jet, who has done what, and pics? Options

[broomhandle]

I am not arguing for KN. I am just against an oil bath. its a pain in the a. if my motor ran perfect. i would probably leave it alone. its a daily driver. not a show car.

if i can find a 1.7 73 i will grab it. or i may go with the KN until i can find something else. really what harm can a KN do?

modern cars do not use an oil bath.

Oil bath air filters are the best at cleaning the air entering your engine. No filter is worst, closely followed by a K&N. OE Paper elements are closest in performance to the oil bath, without the hassle of cleaning the oil bath every 6000 miles. I sure wouldn't switch to the next to worst system from the best one just because it was a little hassle once or twice a year. but that's just me, I guess. BTW, I still have a couple of paper elements left.

I had a K&N air filter on my Honda back in 1989. I put 150,000 miles on that car and the mileage never went down, nor did the oil consumption go up.

I'll stay with me oil bath. Works just fine & fairly easy to clean.

The oil bath was discontinued in 73. The oil bath is actually the best filtering wise. Its just messy. Find a filter housing from a 73 1.7 and use the paper filter if you want, but I hear the round filters are hard to find. I dumped the stock 2L filter for a k&n on my 75 several years ago. The stock filter will go back on when I get the new 2056 installed. The K&N does not filter as well as the stock filter, and they don't add horspower. It makes no difference how much air you put in if it can't get it out.

Don't waste your money, it won't do anything but add more noise into the cabin of the car.

Scientific testing beats anecdotal reporting any day. I rest my case.

thanks to all the posters here for skoolin' a fellow member on filters. think the k&n on the benz will be replaced with a stocker...

it seams this setup is the best. 100 bucks though...

more air in (in a closed area) and shorter travel vrs the oil bath.

the oil is messy. i hate it. and a K&N will last a very long time...

It may last a long time, but it sucks as a filtration device.

KN makes good stuff. how is it any different that a new vehicle? they are not using an oil bath. also, i dont think KN would be making filters if it did not filter.

And you're wrong in thinking that. K&N is in the business of selling product, not making a quality filter. For more air to pass through a given area at a given rate, you have to reduce the obstruction presented by the filter. FAR fewer square inches of filter material (in some cases, less than a quarter of the area of a stock filter) with far larger pores. The result? Much larger particles passing through the filter than with the OE element. Facts of life.

The Cap'n

(IMG:style_emoticons/default/agree.gif) with everything the Cap'n said and will add that on modern cars with MAF, they oil foul the MAF and you have to replace or continuously clean them. As for K&N not selling filters if they weren't better, they would sell you belly button lint if they could. In most cases the only change that happens with a K&N filter is the sound. If it does improve HP it probably reduces engine life.

There are K&N style cone filters that are dry.. AFE makes some. You just wash them off. Not sure how the filtration is.

Oooooooh, those setups are an extra special kinda ugly. (IMG:style_emoticons/default/icon8.gif)

But it's your motor. You've decided based on highly scientific guessing ( (IMG:style_emoticons/default/rolleyes.gif) ) that you have a problem. There is a list of companies that will gladly take your money in the spirit of 'fixing' your problem. And you'll probably notice a difference because you want to find one.

Anyway, get your K&N, and while you're at it , throw on a Tornado™ and some fuel line magnets. Better throw some zMax™ into your oil as well. That little 1.7 is gonna feel like a Cayman Turbo.

Sorry. That was probably a little over the line. I guess I'm just sensitive to people wanting to throw money at problems that don't really exist. Bottom line, It's your car, do what makes you happy.

devils advocate says: so what the hell do the carb'ed engines run ? cuz i always see carbed 2+ liter engines running oil bath air cleaners (IMG:style_emoticons/default/lol-2.gif)

*bump*

I'm pulling up this thread again because I have a situation where my early 1.7 didn't come into my possession with an air filter at all. Instead someone modified this punk-ass Boxster air intake to fit into the bay.

While this thread seems to have devolved into an opinion section about K&N filters, the real question remains: is it possible to buy a decent aftermarket air filter replacement system for the early 1.7L motors?

It's easy enough to say, "Oh, well go find one off a '73 1.7L," but those aren't exactly easy to find.

Where does it get the oil from and what is the regular maintenance one should do ?

Here is a neat idea if you have the right tools and time.

Where does it get the oil? I don't understand. I check the oil with the dipstick and add as necessary. The get-up I have now leaks like crazy, or least it did until I recently pulled the motor for some maintenance. Here's an ugly-ass photo of my soon-to-be ex-setup.

The link you posted certainly shows a beautiful and clever solution and clearly solves the issue for someone with access to welding and fabrication equipment. I think that would be a really nice alternative, but a tad unrealistic for me to hack together.

And so in that spirit I one bought one off ebay and located my Dremel. Wish me luck.
