Would installing a silicon turbo inlet affect mass air readings? The reason im asking is because I purchased a CAI awhile back when I first got my wrx and after install the car didnít run (in my own defense I bought it before I ever researched modding these cars, now I know better than to just slap one on there) I just assumed it was because the car is Cobb tuned for stage 1 and the change in pressure and turbulence was keeping the mass air from getting a consistent read so I returned the CAI. Would installing the silicon turbo inlet yield the same issue? Im not sure if the problem was because the CAI repositioned my sensor slightly or if it was truly just the pressure and turbulence. Id like to replace my turbo inlet if possible but im not going to do this if its not going to get me some result (which im assuming would be a better, faster spool) or if it will keep my car from running. Im planning a trip to cbrd speed factory for a good tune in the very near future to maximize all my recent bolt on goodies so if I need to tune for it to work properly then thatís cool. Also should I go back to the CAI if I replace the inlet? Can I even use the stock intake with the new inlet?
It shouldn't do a lot because it's post MAF. But, it won't help a lot until its tuned for either. Most of the time it's just a safety mod because the stock inlet can and will rip if you replace a turbo. But, eliminating the ribbed inlet for a smooth core inlet can allow for a nicer flow of air.
