Please do not remove your air filter.
Also, be cautious of oiled filters with mass airflow (MAF) sensors, because inevitably it will suck molecules of oil onto the exposed wires and stick there, causing massive havoc and loss of performance with your vehicle as it can no longer read the airflow properly.
I AM SPEAKING FROM EXPERIENCE and this was a brand new extremely high quality filter for the LS1 engine years ago (meaning, I never had the opportunity to over oil it). Thank fully, once I cleaned the MAF it was back to normal-but the wires were full of crud.
I will never put an oiled filter on another engine with a MAF. Not worth it IMHO. YMMV.
