Carbureted euro 1.8?
Ding ding ding - we have a winner!
Turns out that the euro 1.8 with solex used the same box at the T25 bus so they are pretty easy to source. This little project has been going on for a long time so get ready for a pic tsunami.
As we know, I hate noise and I also hate f'ing K&N filters. I also have an unhealthy fetish for the 914/6 air box. We've already established that the Type 4 is not a beautiful engine, but if you look at it, it's really only a cooling fan and sexy air box away from looking quite nice. Just look at the 4-cam and 904 engines. We can't do much about the suitcase cooling fan but every time I see a pic of a stock six air box, I think hubba hubba, I want that. Oh those sexy curves!
After obsessing over this for far too long, I came up with this wish list of features:
• Quiet induction noise
• Don’t restrict air intake
• Fit under rain tray
• Tool-free filter replacement
• Use stock filter element
• Stock appearance
• Dead sexy
I wasn't sure how to pull it off but decided to start by looking at what Porsche did for the only carbed 914 four banger and hit pay dirt. It took pretty much all of the guesswork over air flow since it was used on 2L buses, I figured the opening must flow plenty of air. It obviously looks stock because it is stock AND it used the same filter element as the 2.0L 914 so no need to try to remember what frickin' filter I put in the custom air box.
I sourced this little beauty on ebay for a few bucks and was off to the races. That pic only tells half the story because the stench of cat piss that wafted out of the box when I opened it was priceless.
