Hey I have a 06 Sti and I just installed the Perrin fmic kit with the red perrin short ram intake using stock bov because I haven't gotten a flange for my greddy rz bov. Okay so I got everything hooked up using the stock maf sensor on the Perrin short ram intake. My intake cone the sponge filter came drenched in oil I read on perrins site that they spray it with oil to keep dirt off. So my first pull from first to second gear I hear a pop and the car shut off it would start and shut right off it would barely move so I plug out the maf sensor and the runs but not fast at all and when I plug the sensor back in while the car is running it shuts off. so I cleaned the sensor that didn't work now I want to know what I should do. Should I wash the cone part of the intake with water does the oil necessarily have to be in there? And should I buy a new stock maf sensor from denso? Or will any cheap eBay maf sensor work?

 

Wash the filter and lightly oil it. Too much will dirty your maf. Clean the sensor with maf cleaner and a q-tip. If that doesn't work. And it's the sensor faulting out. The eBay ones will not be a good choice get an oem one. Also check to see if you have any leaks anywhere and also all your vacuum lines are intact. You might have popped something on your first spin.

 

It was a loose intercooler hose by the passenger fender thanks

 

this was going to be my first guess based on the loud pop. when mine blew i thought it was my motor
