Anyone have a spare? I've done some research on the mod and seems like a nice way to get some extra sound out of our engines. Figured I would ask here before putting in a silicon hose and plugging the resonator hole with something (yes I know there are other ways to do it, but I'm not putting a shaving cream cap in my car) Obviously willing to pay for shipping and your trouble if someone is kind enough to send me one, PM me! Thanks!

 

I have the cap/hose posted in this thread (except hose is BLACK): https://rennlist.com/forums/996-foru...irbox-mod.html

I decided not to go with it (I live in NAZIfornia), willing to sell it for what I paid for it + shipping.

 

i found the company that made the orange cap last year, was able to order a sample for free and free shipping. google it. its a bit hard to find, as the company name and address changed. look for the part number, then google the part number. i'll try to look for it again.

 

Could this be the place?

I just ordered a sample for part cpt19.

 

yeah.. thats the place.
i can't remember which one i ordered, but i googled and found the correct size and ordered a "few" different ones to try.

 

I have the orange cap and silicone intake hose on my 99 996. Passes california emissions just fine. Put it on and go get it smogged.

 

This should do it Color matches the oil cap.

 

Is that Tropicana bottle cap CARB certified?

 

That's WAY classier than a shaving creme cap!!!

 

Cpt-19 got delivered today. Simple install and definitely louder, best mod ever considering it was 100% free and took 2 minutes.

 

I got 4 delivered. Definitely noticeable sound improvement and seems to be running just fine. If anyone wants one, pm me and I'll mail it to you.

 

Does this mod work on mk2 cars as well?

 

Tropicana cap wins, it's the new standard.

 

Just curious ... I managed to find the caps from the Niagara Plastics company (they changed names, and changed part #s). I should be able to send a freebie to someone once I get home and get them - I think they gleefully sent me at least 4.

Question, though: I have a Tiptronic car, and this is what my engine bay looks like:



Cap goes where the red circle is, and blue is the 'extra' hose, right? I read somewhere that later generation Tiptronic cars have additional piping which the orange cap mod doesn't close off, rendering it ineffective. Does mine look like one of those, or do I just plug the left part of the Y split and I'm good to go?

 

If you're retaining the stock OEM boot, then you don't need to go anything to the extra hose.
