Cleaned the MAF sensor and replaced my air filter..surprised
Over the weekend I had the hood popped and noted how dirty my KN filter was. On further inspection, the thing was freaking filthy. I'll be honest, I've never cleaned the thing other than shaking it out a couple times after buying it two years and 28K miles ago. I put in the OEM filter which still looks new and I decided to inspect the MAF sensor. It looked clean, but I decided to clean the sensor wire and plate element with a Q-tip and isopropyl alcohol. The Q-tip showed some slight residue/grim, but nothing alarming. I buttoned everything up and went for a spin. The car definitely felt more responsive, but I figured it was in my head even though I'm extremely critical of any changes I make to the car. The next day the car still felt really good. And even yesterday in much warmer temps, the car felt great. I must say I'm a bit shocked at the difference. It's probably because that KN filter was a bit clogged up (there was actually a layer of residue across the filter pleats). I think I'm done with the KN filters because I'm a bit worried about the cleaning kits and the MAF. These Japanese MAF sensors seem to be too tempermental therefore I might stick with stock or maybe an Amsoil filter.

Dave. I cleaned my maf back in the frenzy. Mine was clean and I didn't notice any difference. But I'll bet the reason why the car felt better is because the K&N was dirty. This panel filter seems to get dirty alot faster than the maxima (even though they are the same p/n). Must be because of the fresh air ducting directly into the box.
Clean the K&N and you'll notice the same improvement. IMHO, it should be cleaned every 10k.

Ok, from the K&N website (www.knfilters.com):
So, at 28k, you were about in the cleaning interval...
20. How do I know when to clean the filter?
The general rule of thumb is that the filter needs to be cleaned when the dirt build up gets as thick as the wire mesh. The usual interval is 30,000 - 50,000 miles depending on driving conditions. We recommend that you check your filter about once a year in normal usage.
