Volvo P0420 Treatment

Keeps the notorious P0420 code at bay that's notorious on the Volvo 3.0L T6. Much cheaper to buy this than the individual bottles, but you do have to deal with measuring these out, which is admittedly a pain. But when you're having to do these on two high mileage Volvos, then it's a no-brainer!

wireless like it should!!

we live how this helps alleviate some funny exhaust smells. Our vehicles do seem to run smoother after a treatment (2006, 2013)

Works for me.

I've been using this product roughly quarterly since I first got a cat warning. Each time, the light stays off longer. I know this is a stop gap, but it's allowing me to put off an expensive repair.
