Is it really necessary to reset the ECU when installing a K&N panel filter on a 2k3? If so, how do you do it? I'm going to be putting one in my car tonight. Thanks for any help.

 

No.

The ECU is constantly learning.

 

I installed one of these recently, and it doesnt require you to reset your ECU.

 

I'm glad to hear you are trying out the K&N.

However, it seems that the postings possibly seem to indicate that you have a greater chance of fouling the MFM (mass flow meter) with a oil-impregnated air filter.

Is this true? Will a K&N foul the MFM faster? Is it covered under the warranty?

thanks

I have had one of the K&N drop in's for over 20K miles and already serviced it once. Not a single problem and no ECU reset.

The single biggest issue with 'oiled filters' is overoiling them. I cleaned the filter element with the 'recharge kit' and then put just enough oil back on it to lightly color the pleats (basically the insstructions on the bottle). The thing I like to do is use a clean towel and lay the filter on the towel for a few hours to 'leach' off any excess oil, then wipe the frame of the filter to remove any other excess.

 

OK, I was hoping I wouldn't really have to reset it. The K&N website says that you have to do it so the ECU adjusts to the higher airflow. Thanks for the input guys.

 

I recently recharged my cone filter and did the same as you described. Despite what K&N says about good performace with their dirty filter, a clean recharged filter is AMAZING.

About the ECU, I don't think you really have to reset it. If you do, it wouldn't hurt anything.
