i finally found my boost leak. its on the intakemanifold side of the intercooler. the coupler goes from a bigger size to a smaller size. anyone know which size it is so i can order it. thanks

 

1. Go out to car with tape measure.
2. Remove coupler.
3. Measure coupler.

 

yes that would work if i didnt have to remove my under tray and work 10 hours a day and not have off untill sunday.(would rather not do this in the dark) was trying to see if anyone have the same intercooler that knew already to save me from having to take everything apart twice

 

Ah, sorry, all of my couplers are right on top. Benefits of SMIC. Can't you just measure the piping circumference without having to remove anything?

I'm very surprised that Greddy would have a reducer...why wouldn't everything be the same OD? It should be 2.75 ID couplers if they are OEM sized.

 

no problem. all of my pipes are 2.75 except right where the pipe leaving the intercooler is. its a little bit bigger. im thinking 3" but dont want to order the wrong part. and it is a royal pain getting to it to pull it off. using a ratchet with about 3 inches of turning space (it takes 10 minutes just to get the damn clamp off.) i would rather have the part there and do it all at once.

 

did you ever find the size? thats exactly what i need to know...
i will if i have to get it off to measure, but i rather not seeing its a wrist stretching job.
