Portyansky Posted March 10, 2014 Share Posted March 10, 2014 I am not after any power gain (but won't complain if I get some) just looking for that engine "roar". Link to comment Share on other sites More sharing options...
bomberlegacy Posted March 10, 2014 Share Posted March 10, 2014 You'll possibly lose power, maybe run poorly too. I hear Cobb intakes are loud though '08 Legacy 2.5i - hybrid intake - delta 1000 - E85 - magnaflow exhaust Link to comment Share on other sites More sharing options...
Portyansky Posted March 10, 2014 Author Share Posted March 10, 2014 So allowing your engine to breath better will cause less power? Hmmm Link to comment Share on other sites More sharing options...
ras06LGT Posted March 10, 2014 Share Posted March 10, 2014 For almost all modern engines which use a torque demand based mapping system (as in, the computer uses accel pedal position to determine driver requested torque, then uses requested torque to set a throttle plate angle) a high flow filter won't really do much w/o a tune. The stock map is only calibrated to expect a certain level of air flow. Adding a higher flowing filter just means the car will be seeing high air flow at a lower accel pedal position, which could do strange things to how the engine runs as the ECU doesn't expect it. The top end of flow is still map limited (unless our maps extrapolate beyond the cal tables - still unreliable). Just search this site for plenty of testimony as to why drop-in after market intakes don't work well w/o a tune. Besides, the stock intake is already a cold air intake and is good to well above 300 HP. Link to comment Share on other sites More sharing options...
Portyansky Posted March 11, 2014 Author Share Posted March 11, 2014 I guess the "kid in me" won't get his growl of a sound. Link to comment Share on other sites More sharing options...
