Ok so its my firster time with my si in this cold weather. I start my car and let it idle till it begins to drop in rpm's. I start driving being careful not to shift over 3k rpm's until care is warmed up. It seems to take forever for this car to get to temp when driving. I drive for a good 8-10 mins before its at 4 bars! I am pondering if I should put my factory air box back on inplace of the SRI I have. Will this help my car warm up faster?
