Good options, good value for money
Good product, a solution to save money rather than replacing the part ! Have done this about a week ago let’s see how long it lasts !

Surprised how good value
Great value for money 😀 transformed performance on a 2003 petrol and brought emissions to pass level. Spray as a mist into air body whilst engine is set to 3000 revs the revs will purge and judder after take for a spirited run 😉

Works as preventative not if your CAT is stuffed
Would've been great if this stuff worked for me but my Catalytic convertor must be shot. They may have been a slight improvement but the engine & stability control lights are back on and it runs rough at times and struggles up hills, poor performance when pulling away. I suspect this would be a good idea to use every 3-6 Months as a preventative in keeping the CAT in good health as long as the CAT is in good health to start with.
