Let's take this to another level, and I would like everybodys thoughts on this.
Low level junk parts = American / GM.
Mid level parts = Toyota.
High Level parts = Aftermarket?
Thoughts? I'm going on "not every company can do everything well". That's why there are specialized manufacturers out there.

Yeah or to whoever has the K&N/TRD filters before. I've heard some people had a lot of dirt and oil buildup on the MAF and around the opening of the throttle body. I think it was because they put too much oil to recharge the filter.

The current Quality problems experienced by Toyota is "too much, too soon" syndrome. When the pressure is up to produce a bigger quantity (to keep up with demand) the ability to line up resources, hardware and soft, is the challenge. Toyota is not immune to growing pains. The lure of higher sales is sometimes deadly. Hopefully Toyota will not fall prey.

lol...I was quoted over 700 from a dealership for a new MAF, 187 isn't anything. A refurbished one was $450, and the one I'm getting from cali is 125, shipped overnight.
The way I see it, if you see improvement from a K&N, you needed a new filter anyway. I tried it in an older Buick Lesabre with a 3.8L V6, a Jeep Cherokee with the 4L I6 and some computer tweaking as well as other mods. Never noticed a difference, except that my filter needed cleaning more often than I had to replace the old paper ones. Not worth the headache, or the chance that foreign objects are finding their way into my engine or messing up my sensors.

I'm waiting for the Amsoil Ea synthetic Air filter to be offered for the 2005 ES personally. Good for 100,000 miles & all you need to do is vacuum & reinstall, not re-oiling.

K & N's have been in every car I have owned since I was 16. I do worry about the MAF and havethus not replaced my Gen2. I had a CAI in my gen1 IS300 and it contributed to rough shifting since the set-up does not use the OEM resonator box. I removed and dropped in a OEM box filter after installing the factory airbox. I have know people who had to get the MAF sensor replaced due to K&N oil. I love these filters, but I do not want to have a warrenty void issue. Sure, you can keep the OEM and drop it in beofre delaer visit, but I think I will stick paper for now.

For those interested in a long lasting synthetic air filter that never needs to be re-oiled (only vacuumed once a year), here is some info...

I highly recommend it & less expensive than a K & N filter too boot.

I've heard some good things about the green HKS super hybrid though, no Oil, no mess.

I had a K&N filter in my GS. What a nightmare! It contaminated my MAF, which caused my engine to knock on hard acceleration. I was lucky not to sustain permanent damage to the engine. I will never again use K&N or any other oiled filter. Not to mention that it cost me a lot of $$$ by the time I got to the bottom of what was causing the knocking.
