Want to buy Original 1.7 air cleaner, Looking for correct complete air cleaner for 1.7 motor Options

[jkb081]

QUOTE[I see. Thank you. My issue is the intake horn is pressing down on the flapper rod that connects both flappers, thus preventing it from proper function. So I assumed I have the incorrect air cleaner.]QUOTE

The horn should point to the side of the car. See below. You should be able to rotate the bottom of the cleaner (with the horn) when the clips are undone. The top half's orientation is fixed by the rubber connector to the throttle body.

As to the covered up numbers in the trunks, they would (should) be the same as the top number on the Karmann plate: 2639599. This means your car was built on the 3rd day of the 26th week (of 1973.) Or Wednesday, June 27th. This, and the high VIN# (27001) would put it fairly late in the '73 model run, which I believe would have ended in August or September.

The scratched out bottom number is the original paint code.

Hello Ron. Thanks for the great information on the air cleaner and explanation of the Karmann badge. I wonder if I might ask for another favor? Interpretation of engine and transmission numbers. I afraid I might have a "Frankinstein" car. lol! Could explain why certain things do not look correct and also explain the fitment issues Im having. Engine number: EA106342, Transmission number: 914/11HA0004761. Thanks for your help.

Happy to help. I knew almost nothing about these cars 6 months ago and learned everything from the helpful folks here!

There are a lot of threads on engine numbers, and a lot of people more into them than I am, but based on the numbers on my original '73, yours look to be correct. Or at least not out of whack. Hopefully others will chime in.


One thing you should do, if not already, is to put your info into the VIN Database (top thread in this forum) Once your car is slotted in, you may be able to see some engine #'s of cars that were built at or nearly at the same time. Could be a good gut check.

Cheers,

Ron

For reference this is what the original elements looked like

Found one on ebay, didnt need to go to the garage (IMG:style_emoticons/default/smile.gif)

Maybe 'Mr. Rubber' can produce a rubber ring to place on top of the NAPA and WIX elements to help achieve proper sealing ??? (IMG:style_emoticons/default/idea.gif) ???

What? No rubber ring needed for seal if proper filter is selected. :shades2:eBay post is way overpriced! (IMG:style_emoticons/default/hissyfit.gif)

The $7 WIX filter I ordered will be here this weekend. If there's a gap, I'm thinking of trying something like this and will report back.

Well, unfortunately, the NAPA 2909 discussed above does NOT fit the stock 1.7 round cleaner. It's way off (yellow circle is what the ID needs to be.)

The return shipping exceeds the original cost so if anyone needs it let me know.

[rhodyguy]

That's a plastic housing? I wonder if the fittment differs with the metal one?

Yeah, really easy to see the nasty air gaps under that one.

Ill save some time and just re-post a previous discussion on this issue:

Man, that was 12 years ago lol. I have been doing this way to long.

Never personally tried it but I am still betting the K&N E-3270 is probably going to be the best aftermarket option based on the specs.

And im curious enough to find out now that I just dropped 83 bucks after tax and shipping on the last one summit had in stock to find out. https://www.summitracing.com/parts/knn-e-3270

Ill let you know how it goes...



Otherwise
This is probably the best adaptation of a non stock filter i have seen so far, not sure how well it seals at the top though

I've run the NAPA 2909 filter in my all original 73 1.7L for years, not fitment problem. The filter in your photo appears to be much larger than the inside diameter of my filter which is 6.5"? (IMG:style_emoticons/default/confused24.gif)

Hold the horses, I just measured my air filter, and the NAPA box is labeled #2909 but the filter has #2011 inside! That is the filter I've been running in the 73 air filter housing all these years. (IMG:style_emoticons/default/confused24.gif) .Sorry for the confusion y'all!

Ok, so my K&N E3270 showed up and I made it out to my 1.7 to take a look at it this weekend.

So... first off worth mentioning is how the factory filter is supposed to fit. snug around the inner ring. So snug that you can hold it upside down without it falling out.





This is how it was designed to seal, not via the top and bottom. Thankfully i recently drove through Redrock country and the remnants of this in my air filter housing make it very apparent. You can see on the top part of the filter housing how little of the filter is actually touching at the top as dirt has made it all the way into the inner most ring




Comparison of the Factory filter and the E-3270









Overall height of the E-3270 is roughly the same height as the inner ring of the factory filter however the OD is slightly larger so it isnt grabbing the inner ring though it is close enough that there are no gaps in the upper and lower contact surfaces. Also the OD is not as large and there are less pleats in the filter material, so I imagine there is considerably less filter material overall, not necessary a bad thing, just means you may need to service the filter more often, but the K&N is washable so that is somewhat of a non issue.

Upon test fitting it the height is perfect. the housing can be clamped closed with only minimal pressure and once the housing is clamped down there is no movement of the filter at all. I suspect this one should seal well enough to actually filter the incoming air.

However after this filter arrived, knowing how they fit now, I decided to poke back into the K&N catalog and found a newer filter that wasn't previously listed last time I looked...

The E-9145 has an ID listed at 124mm (3mm less than the E-3270) and 82mm height (1mm shorter than the E3270). This may be a perfect fit on the inner ring. Biggest possible downside I see is the OD is only 149mm where as the OD on the E-3270 was 160, so its going to be even thinner (12mm vs 16mm) and most likely have even less filter material. Its also 15 bucks cheaper. (actually as I was able to get this one with amazon prime free shipping it came out like 30 bucks cheaper $55 vs $85 )

Only one way to find out how well it actually works though, and I like spending money to know things i guess, so i ordered one up, should be here this week.
