in order to achieve no CEL w/ my testpipe, im gonna do this mod. im just wondering what most of you have done either getting the longer non-foulers vs. the shorter ones. just trying to get some others input. thanks!

also, is it pretty tricky removing the second o2 sensor? i have fat hands and the space looks small...[=(]

i used the 42009's and they have been working great.. the space back there is tight and expect your hands and forarms to be beaten up but you'll eventually get it.. good luck

I could not get either of these to work without cutting off the heatshield. The sensor was just to big to fit inside the threaded part of the spacer and I even bored it out a little. I ended up just getting a testpipe file from APR that solved all my problems. Has this mod actually worked for anyone else other than sean1.8t?

As far as removing the sensor, just unplug it first and remove any kind of heatshield you may have and it should be ok. My hands are average size but not small. Here are some pics.

I've had mine in for 15,000 miles, not one CEL. I'm running the ATP test pipe and have no clearance issues.............

How much is the APR TP file for current APR users? DPP?

I put my non foulers on before I installed the test pipe. Used 1 short and 1 long, drilled out the long so the sensor would fit. No cels on my AEB.
