which you consider the best solution for installing the O2 sensor?
The Riva solutión : http://www.4-tecperformance.com/inde...oducts_id=2296
or the R&D solution http://www.4-tecperformance.com/inde...roducts_id=882

Drill and tap. Riva makes it easy but you can find drill and tap for half that on amazon.

No personal experience with the extender but I have heard bad things,
here is the link that I posted for the older manifolds that are thin,
the key is getting the pilot hole drilled dead center, and having a good clamp on the manifold so it will not move,
15mm drill bit is just enough for the oxy sensor to go in to the bottom, but you only need to tap the top 1/2"-do not tap the compete length of the hole,

I ran the extender. I had a massive exhaust leak from it. I pulled it and got rid of it. I tapped the manifold (pre 08 ) and it held good.
Used 2 drill bits and a tap. Smaller bit to drill all the way through and a bigger one to drill just enough to tap just enough for the sensor.
There is another thread about stripped threads check that out there is a picture of a manifold cut open so you can see what your up against.
I also use anti seize on the threads.

Drill and tap 100%. The only way to do it.

I see a lot of people saying 08+ manifold are the way to go?
Because wall a bigger compare to previous model?!

Seems that the water jacket is farther away from where we drill and tap. Less chance of hitting it.

this is the picture of the 06 mani cut in half, the 08 and newer have thicker walls of material to drill in,

You can see why it leaked. The metal flange is to thin and distorts when clamped. This was a major leak.
