2006 GX470 with 74500 miles on it.

I usually always install a K&N filter in my vehicles. Somehow this has escaped me for several years. I just noticed yesterday that I never put one in.

Is it worth installing one at this time? I plan on keeping the vehicle a couple more years.

If I recall, installing one in a car with mileage requires to reset the computer so everything can adjust to the new airflow. By disconnecting the battery for about 30 minutes.

Thoughts appreciated.

Thanks

I just put one on that I purchased from eBay used. I re-oiled it and installed it. I'm not really looking for performance out of it, I'm just trying to save a few bucks and the trouble of going out and getting the OEM element. I did reset the ECU after the install by disconnecting the EFI fuses for 10 min. No need to disconnect the battery.

To answer your question, no it would not hurt to have one. Just make sure you don't over oil it as it will damage your MAF sensor.

I am not a big fan of factory elements and have installed aftermarket filters on all my vehicles. Not sure how well the K&N filter compares with the OEM for the GX but I'm sure it does well, maybe better since its oiled.

Thanks for the reply

I will go ahead and pick one up.

Never thought about pulling the fuse to the ECU. Much easier than disconnecting the battery for 30-60 minutes.

I might want to the same thing....where is the ECU fuse located and is it clearly marked?

If you are using the disconnect battery method to reset the ecu, once the cable is off, just hit the brakes and when it tries to light the brake lights it will burn off any power left in the system, then you can hook it back up in a couple of minutes with the same results, much quicker.

As for filter elements, I'm not a fan of using oiled elements in cars with MAF sensors, recipe for trouble. Are there any washable dry element filters available for this application? I'd go that route over K&N if possible.

I agree on the filter issue. Amsoil makes a 25,000 mile synthetic media filter. Oiled filters are for the track along with other mods. Nothing to be gained from them other than oil on you MAF.

It's located in the fuse box under the hood next to your battery. You will want to pull both EFI fuses (20 and 10 amp). Let it sit for 5 min and plug them back in. I do this everytime I clean the MAF as well.
