Review on FRAM Extra Guard Air Filter, CA3914 for Chevrolet, GMC, Pontiac, and Winnebago Vehicles by Sammie Rodriguez
Improved Airflow?: Air Filter
You may think I'm crazy, but. After every full throttle in my '03 Corvette I got a CEL. Codes indicate O2 sensor and too rich. I remember not having the code until I changed the air filter. The first was WIX and I got CEL with every WOT. I tried a NAPA gold air filter. The results are the same. I installed this fram and did 10 WOT passes. without codes. I suspect the other filters were more restrictive and not allowing enough airflow into the WOT. It seems unlikely, but these are the facts!
