If you have questions about installing yourself...ask.

 

the o2 sensor bung and all fit perfectly? they look killer! i just need the right damn tools to do it myself.

 

It was kind of a pain in the ass to install the o2 sensor but it fit snug like its supposed to! Remember to install that last!!! Torque down the sensor first, then screw in the tiny 10mm bolts that hold the harness, then connect the plastic connectors.
