Re: Cold air intake bypassing ECU, issues?
It really depends on the climate you live in and the average ambient air temp. I live in the PACNW, and it really is only hot here for two months a year, if your lucky. And when I say "hot" I mean 85. I have owned so many TD's over the years that had aftermarket intakes w/ out ducting to the ECU and I have never had an ECU failure due to it. HOWEVER, if I lived in an area that consistently had high ambient air temps, ESPECIALLY in areas with summer temps soaring in the 100's, I would think about keeping the "air draw" over the ECU board, or install a cooling fan as previously described. If you live in Alaska, your underhood temps are freeeeeezing, those guys don't worry so much about electronics overheating. But, after all this being said, the HP gains of an aftermarket intake are nil. So, if you are really worried about ECU failure due to overheating, keep it stock.
