Hello guys what's up?

My friends car listed above, the catalyst converter got dirty and wanted to add some additive catalyst cleaner unplugged the o2 sensor as shown the picture below, but when he put the cleaner it drops below the the o2 sensor location.
Using this type of cleaner:
dpf catalyst cleaner Powermax.

Hello, I'm Danny.

What kind of container does this Powermax cleaner come in and how is it supposed to be applied? Get back to us and we'll go from there. Hope this helps and thanks for using 2CarPros.

On his car all the cleaner drops below the car it's like there is a hole or something in section between the manifold to the catalyst converter.

Hello again.

My suggestion is to take the application straw and bend into a short 45 degree angle. If you make it short then spray from the top at the o2 sensor location in a 360 rotation. That will help with the application. I use Liqui Moly brand for catalyst cleaner. I've attached a picture below of Liqui Moly. Hope this helps and thanks again for using 2CarPros.

Hello again.

I've attached the picture again below of the product I've used with great results. I would suggest making a 45 degree angle on the applicator tip so you can spray in a 360 degree pattern to get all the converter substrate saturated. Hope this helps and thanks again for using 2CarPros.
