Efini Y pipe Part nummer and info request
I'm looking for the PN of the OEM alloy bridge tube from the Y pipe to intercooler section.
It's for replacement of the plastic one.
Was the lower Y-pipe section changed/updated over the years? Is there any gain in replacing the lower and upper Y pipe as one piece or is it enough to replace the upper one for cracking insurance?
Just asking.

try here.....$249 (link below)
most have changed to the Efini part when the haye problems or just upgrade their system....I've been told that it flows better than stock.
I would change both to get the plastic out.....IMHO.

You need the crossover pipe and the part it attaches to as it's now as gasket that sits between them with two bolts on it so you can't use your original one. The half of the y-pipe with the actuator on it the same as the stock earlier ones but the other half is different.
you need both parts. (the y pipe and the crossover pipe) they are sold as a kit. here are pics from my install:

While a major advantage to the Efini kit is the elimination of the soft coupler, the design of the 'Y' pipe itself is slightly different to allow better flow. You can see the difference in the 3rd pic posted by Theorie, particularly around the BOV hose connection. Exactly how much improvement is debatable, but it's still an improvement.
yep thats me. hey neal, i remember you! i have a new msn name. it's in my rx7club profile i think
