I saw a pic on ebay of a 2001 with the stock intake completly taken off and an aftermarket air filter (K&N or APC I think). Anyway if the airflow sensor is not connected what does this do? Is it important?
That sensor tells the computer the temp. of the air coming in. Its helps in adjusting the amount of fuel being delivered. If its not connected you will get a CHECK ENGINE light. Maybe it was just the pic, but the intakes SHOULD have the hole. If not make it yourself.
A hole ?? A place to put the sensor or for the air to get to the sensor. Is it possible to take the stock sensor and put it b/w the filter and the intake manifold when ther is only about 5 inches b/w the 2??
