Just a word of caution. You should not use any other filter with the URD TCAI. We carefully designed the placement of the MAF sensor, the tube, and the filter to work together to provide a very clean and accurate signal from the MAF sensor. The curved velocity stack of the filter is very important to provide smooth air flow into the tube before the MAF. I have seen people attempt to use other filters and they induce all kinds of turbulence to the air flow causing a very poor and unstable MAF reading.
Maybe the filter is what is wrong with my MAF readings. About once every 3 months I get a CEL on MAF errors. When I check the readings in the driveway, they seem fine. This only happens when I am driving down a certain stretch of I-10 that is very windy and I am pulling 70-75 MPH uphill. I had forgotten all about it since I haven't had a CEL in months, but I got one yesterday driving that same strip in a crosswind.
At first, I thought it was my soldering job on the wires to the MAF. However, I took all of that out and re-soldered (heatshrink and all) a few months ago. After yesterday's CEL, I was beginning to think it was the MAF itself ($130 part!). Hopefully it is just bad turbulence due to a really clogged filter.
I will be ordering a new filter this week.
